To this affect we have now released version 1.0.0-RC1 which can be downloaded on the download page.</p><hr><h2 id=story>Story</h2><p>Strolch as a component based software agent has been two years in the making. The concepts in Strolch have been taken from a proprietary planning, scheduling and controlling software agent, which was, and is been, used in industrial automation, logistics and production. Strolch was created to bring the concepts, which were working well for small teams to go-live with large projects in short to medium time-frames to the open source world.</p><p>Strolch was completely rewritten using the key concepts of a parameterized object model and a component based agent but remembering which clutches the original implementation had, thus trying to eradicate those without bringing in new ones. It might not be perfect in version 1.0.0, but it is a starting point form which to carry on from.</p><h2 id=features>Features</h2><p>Strolch isn&rsquo;t feature complete by a long shot, but it sure has got many features which make it useable in a concrete project, thus making sure it is not vaporware =)</p><p>The following is a list of key features, many of which were driven by concrete project requirements:</p><ul><li>Separate containers for models (mandates)</li><li>Parameterized model with full CRUD for Resource and Order objects</li><li>Timed values on Resources to map values by time</li><li>Built-in versioning of model - configurable by Realm</li><li>Transparent runtime modes: TRANSIENT, CACHED, TRANSACTIONAL*</li><li>Service and Command pattern for reusing functionality</li><li>XML File based persistence layer*</li><li>PostgreSQL persistence layer*</li><li>Querying using a fluent API</li><li>Services to import and export a model to XML</li><li>Integrated authentication and authorization to validate user privileges using Privilege</li><li>Ready to use Observer pattern</li><li>(currently) Read-only REST API to access the agent model remotely</li><li>Configurable environments</li><li>Opt-in audit trail (including read access, and the audits themselves)</li><li>Basic components required to communicate with external devices using TCP/IP</li><li>With the light weight implementation, where there are basically no third party libraries required for the normal runtime, Strolch has a minimal foot print which allows it to run on small devices for instance a BeagleBone Black. Using the in-memory mode, it is an easy feat to set up test environments with little to no further requirements than the JVM.</li></ul><h2 id=future>Future</h2><p>So what is planned for the future? Although Strolch has quite a few interesting features, it is by no way feature complete. The greatest wish is for Strolch to become a community driven platform, so many new features will arise in the future, but at least one major future feature which will be tackled in the near future and will certainly drive the next major release is a planning and scheduling engine using a Gantt chart to visualize the schedule.</p><p>The planning engine will use the timed values on Resources extensively to create a planning engine on which Workflows can be placed and allowing to detect violations and bottlenecks.</p><p>An extension of the planning of the scheduling engine will allow more than just placing Workflows on Resources, but actually searching groups of Resources for a time slot of when to place tasks. This will allow to use capacity constraints to plan and schedule workflows using different algorithms, and respecting calendars etc.</p><p>Further time will be spent on giving Strolch it&rsquo;s own UI. Currently the idea is to use Google&rsquo;s Polymer to implement the UI, thus creating reusable widgets that can be used in projects.</p><h2 id=take-it-for-a-spin>Take it for a spin</h2><p>So, now the important part is for new users to start using Strolch for their own projects. Go ahead, check out the Downloads page for the latest release and then checkout the two tutorial applications to get yourself up to speed!</p><p>Don&rsquo;t hesitate to send us feedback or questions, we will be delighted to help you get your Strolch-based application up and running, or provide feedback to your concerns!</p><h2 id=developers>Developers</h2><p>Robert von Burg

 can be downloaded on the <a href=/download>download page</a>.</p><hr><p>While implementing a use case in a Strolch based application it was detected
 that an essential parameter type was missing, the <code>DurationParameter</code>. This
 parameter currently stores the value as a long in memory and serializes to
 <a href=http://en.wikipedia.org/wiki/ISO_8601#Durations target=_blank>ISO8601</a>.
 As soon as we move Strolch to Java8, we will change this to use the
-<code>Period</code> class in the new Java8 date and time API.</p><p>In addition to the new parameter, a couple of other changes were made:</p><ul><li>32c1785 [Major] Added Session timeout handling</li><li>d55371e [Minor] fixed component version descriptions</li><li>c1cdfbb [Bugfix] added missing cloning of StringSetTimedState in Resources</li><li>8f50a15 [Major] changed XML format of time value of TimedStates to be ISO8601</li><li>5fbbe50 [Bugfix] fix NPE when cloning Resources with no state vars</li><li>b77f4b2 [New] added TimeVariable.clear()-method</li><li>Updated sub-module ch.eitchnet.utils to 906d24d</li><li>Updated sub-module ch.eitchnet.privilege to aa16887</li></ul><p>So, Strolch 1.0.0-RC4 is out the door, go ahead and <a href=/download>try it out</a>.</p><footer class=footline><i class="fas fa-user"></i><a href=mailto:eitch@eitchnet.ch>Robert von Burg</a> <i class="fas fa-calendar"></i>09/10/2014</div></footer></div></div><div id=navigation><a class="nav nav-prev" href=/blog/post-00005/ title="Strolch Release 1.0.0"><i class="fa fa-chevron-left"></i></a><a class="nav nav-next" href=/blog/post-00003/ title="DB Initialization: Release 1.0.0-RC3" style=margin-right:0><i class="fa fa-chevron-right"></i></a></div></section><div style=left:-1000px;overflow:scroll;position:absolute;top:-1000px;border:none;box-sizing:content-box;height:200px;margin:0;padding:0;width:200px><div style=border:none;box-sizing:content-box;height:200px;margin:0;padding:0;width:200px></div></div><script src=/js/clipboard.min.js?1650626697></script><script src=/js/perfect-scrollbar.min.js?1650626697></script><script src=/js/perfect-scrollbar.jquery.min.js?1650626697></script><script src=/js/jquery.sticky.js?1650626697></script><script src=/js/featherlight.min.js?1650626697></script><script src=/js/highlight.pack.js?1650626697></script><script>hljs.initHighlightingOnLoad();</script><script src=/js/modernizr.custom-3.6.0.js?1650626697></script><script src=/js/learn.js?1650626697></script><script src=/js/hugo-learn.js?1650626697></script><script src=/mermaid/mermaid.js?1650626697></script><script>mermaid.initialize({startOnLoad:true});</script><script type=text/javascript>var _paq=window._paq=window._paq||[];_paq.push(["setDocumentTitle",document.domain+"/"+document.title]);_paq.push(["setCookieDomain","*.strolch.li"]);_paq.push(['trackPageView']);_paq.push(['enableLinkTracking']);(function(){var u="https://piwik.eitchnet.ch/";_paq.push(['setTrackerUrl',u+'matomo.php']);_paq.push(['setSiteId','2']);var d=document,g=d.createElement('script'),s=d.getElementsByTagName('script')[0];g.type='text/javascript';g.async=true;g.src=u+'matomo.js';s.parentNode.insertBefore(g,s);})();</script></body></html>

 another <a href=https://github.com/strolch-li/strolch target=_blank>organisation</a> on GitHub, so if

privilege checking.</p></li><li><p>One Transaction at a time - no TX inside of another TX.</p></li><li><p>Commands are added to TXs and performed on close: <code>tx.addCommand(Command)</code> and then <code>tx.commitOnClose()</code></p></li><li><p>Only access <code>ElementMaps</code> if really no other way, mostly use <code>tx.get*By()</code>, <code>tx.findBy()</code> and searches - if a specific get is missing, then add the method to <code>StrolchTransaction</code> and send a pull request!</p></li><li><p>Use <code>tx.stream*()</code> methods to iterate over all elements, if you don&rsquo;t want to use a search.</p></li><li><p>Don&rsquo;t write logic in REST API beans.

it, and are thus reusable.</p></li><li><p>Subclass <code>ResourceSearch</code>, <code>OrderSearch</code> and <code>ActivitySearch</code> when implementing use-case specific search - this allows privilege checking.</p></li><li><p>One Transaction at a time - no TX inside of another TX.</p></li><li><p>Commands are added to TXs and performed on close: <code>tx.addCommand(Command)</code> and then <code>tx.commitOnClose()</code></p></li><li><p>Only access <code>ElementMaps</code> if really no other way, mostly use <code>tx.get*By()</code>, <code>tx.findBy()</code> and searches - if a specific get is missing, then add the method to <code>StrolchTransaction</code> and send a pull request!</p></li><li><p>Use <code>tx.stream*()</code> methods to iterate over all elements, if you don&rsquo;t want to use a search.</p></li><li><p>Don&rsquo;t write logic in REST API beans. Delegate to other services, making your code reusable!</p></li><li><p>Marshall to JSON using the <code>StrolchElementToJsonVisitor</code>.</p></li><li><p>Unmarshall JSON using <code>FromFlatJsonVisitor</code> or if needed <code>StrolchElementFromJsonVisitor</code></p></li><li><p>References between objects is done by adding a <code>ParameterBag</code> with the id <code>relations</code> to the object and then <code>StringParameters</code> with the value being the ID, the UOM set to the type of element being referenced and the Interpretation set to the class type being referenced.</p></li><li><p>Very seldom and sparingly use <code>tx.flush()</code> if you need to perform first some work and then as late as possible call <code>tx.commitOnClose()</code></p><p>The <code>flush()</code>-method flushes everything, i.e. rollback isn&rsquo;t possible anymore.</p></li></ul><footer class=footline></footer></div></div><div id=navigation><a class="nav nav-prev" href=/documentation/model/ title=Model><i class="fa fa-chevron-left"></i></a><a class="nav nav-next" href=/documentation/runtime-configuration/ title="Runtime Configuration" style=margin-right:0><i class="fa fa-chevron-right"></i></a></div></section><div style=left:-1000px;overflow:scroll;position:absolute;top:-1000px;border:none;box-sizing:content-box;height:200px;margin:0;padding:0;width:200px><div style=border:none;box-sizing:content-box;height:200px;margin:0;padding:0;width:200px></div></div><script src=/js/clipboard.min.js?1652447804></script><script src=/js/perfect-scrollbar.min.js?1652447804></script><script src=/js/perfect-scrollbar.jquery.min.js?1652447804></script><script src=/js/jquery.sticky.js?1652447804></script><script src=/js/featherlight.min.js?1652447804></script><script src=/js/highlight.pack.js?1652447804></script><script>hljs.initHighlightingOnLoad();</script><script src=/js/modernizr.custom-3.6.0.js?1652447804></script><script src=/js/learn.js?1652447804></script><script src=/js/hugo-learn.js?1652447804></script><script src=/mermaid/mermaid.js?1652447804></script><script>mermaid.initialize({startOnLoad:true});</script><script type=text/javascript>var _paq=window._paq=window._paq||[];_paq.push(["setDocumentTitle",document.domain+"/"+document.title]);_paq.push(["setCookieDomain","*.strolch.li"]);_paq.push(['trackPageView']);_paq.push(['enableLinkTracking']);(function(){var u="https://piwik.eitchnet.ch/";_paq.push(['setTrackerUrl',u+'matomo.php']);_paq.push(['setSiteId','2']);var d=document,g=d.createElement('script'),s=d.getElementsByTagName('script')[0];g.type='text/javascript';g.async=true;g.src=u+'matomo.js';s.parentNode.insertBefore(g,s);})();</script></body></html>

id=body-inner><h1>History</h1><h2 id=overview>Overview</h2><p>Strolch is an open source component based software agent written in Java and can be compared, in a light sense, with the Java EE stack: Strolch takes care of persistence, implements Services for use cases, Commands as re-usable algorithms and has a parameterized data model.</p><p>Strolch has an intrinsic understanding for mandates, which are called realms so that a single agent can be used to implement applications with multiple users/customers for instance in SaaS environments.</p><p>The parameterized data model consists of three top level objects, Resources, Orders and Activities. These objects can have any number of ParameterBags which in turn can have any number of Parameters on them. This allows for a very dynamic modelling of data structures including modification at run time. Multiple ready to use Parameter types are already implemented which handle the primitive types in Java including ListParameters for collections of these primitive types.</p><p>One of the main features of the Strolch agent, is that persistence is handled transparently and the user must not be worried about databases and the likes. Currently there are two implementations for persisting the Strolch model, a PostgreSQL and an XML file persistence. Currently both persistence layers persist the data by converting to XML and storing it into the database. The XML file persistence stores each object in its own file.</p><p>The agent itself has a small memory footprint and requires very few components to start. For the agent to be useful it needs additional functionality which is implemented in StrolchComponents. Each component is registered via its Java interface on the agent and is bound to the life cycle of the agent. When the agent is started, these components can be retrieved and used to perform any number of functionalities. This is the preferred way to extend the Strolch agent. There are a number of components already implemented, e.g. the ServiceHandler which executes Services in a controlled fashion and can validate authorized access to these services.</p><p>No software product is complete without a system for authentication and authorization. Strolch implements this by using the Privilege framework which has been written by Robert von Burg. The standard ServiceHandler detects the existence of the PrivilegeHandler and then validates that the user has authorization to perform the service. This framework is implemented as its own Strolch component, thus can be retrieved at any time during execution to perform fine grained and special authorization validation.</p><h2 id=motivation>Motivation</h2><p>A question often asked is why create Strolch. What are its benefits in contrast to using Java SE with an OR-Mapper like Hibernate, or using Java EE on JBoss or Glassfish? Especially since many of the features existing in those stacks needed to be re-created in Strolch.</p><p>The first answer to this question is that those systems are often overly complicated and bloated. Java SE with Hibernate certainly is a viable option when it comes to being light-weightier but Hibernate, even though it is supposed to, often fails to truly help remove the need to really understand an RDBMS. Often enough Hibernate will just get in the way of the most important part of development: writing the business code. Being an OR-Mapper which is supposed to implement all the nitty-gritty details of an RDBMS system, Hibernate, and JPA for that matter, still often has the developer go back to understanding these details.</p><p>Strolch tries a different approach to persistence. Instead of writing pojos/entities, Strolch&rsquo;s model has the concept that each element&rsquo;s attributes are part of a composition pattern: each attribute is its own object and thus can be dynamically changed at runtime, but also makes persistence of such an element generic. Instead of having fixed attributes for a concrete class, these parameters are stored in a map and are accessed through the parameter&rsquo;s ID.</p><p>Assigning an ID to an attribute for accessing of course brings its own downsides, i.e. the parameter might simply not be there, when being accessed. This is certainly an issue that the developer must handle, when implementing a project using Strolch, but allows the developer to not need to worry about persistence, as this is generically handled.</p><p>Since the persistence is generically handled, and Strolch stays lightweight on its requirements at runtime, the developer can quickly get down to what is important for business value: Writing the business logic and the presentation layer. Here too Strolch tries to help the developer by bringing in concepts which are easy to follow: Use cases are implemented as Services, and re-usable business logic is put into Commands.</p><p>There will be reasons against using Strolch, as there will be against using the Java EE stack, or an OR-Mapper or even the Java ecosystem for that fact. Important is to note, that the concepts behind Strolch are nothing new, but have been implemented in at least two previous proprietary products. Since those products are not accessible to the public, it was decided that a re-implementation might be of use to the programming community at large.</p><p>Currently, there is at least one company using Strolch in a commercial project which helps drive Strolch&rsquo;s development and further motivates its existence.</p><p>Strolch is an open source project and licensed under the Apache License 2.0.</p><p>##Technology

id=body-inner><h1>History</h1><h2 id=overview>Overview</h2><p>Strolch is an open source component based software agent written in Java and can be compared, in a light sense, with the Java EE stack: Strolch takes care of persistence, implements Services for use cases, Commands as re-usable algorithms and has a parameterized data model.</p><p>Strolch has an intrinsic understanding for mandates, which are called realms so that a single agent can be used to implement applications with multiple users/customers for instance in SaaS environments.</p><p>The parameterized data model consists of three top level objects, Resources, Orders and Activities. These objects can have any number of ParameterBags which in turn can have any number of Parameters on them. This allows for a very dynamic modelling of data structures including modification at run time. Multiple ready to use Parameter types are already implemented which handle the primitive types in Java including ListParameters for collections of these primitive types.</p><p>One of the main features of the Strolch agent, is that persistence is handled transparently and the user must not be worried about databases and the likes. Currently there are two implementations for persisting the Strolch model, a PostgreSQL and an XML file persistence. Currently both persistence layers persist the data by converting to XML and storing it into the database. The XML file persistence stores each object in its own file.</p><p>The agent itself has a small memory footprint and requires very few components to start. For the agent to be useful it needs additional functionality which is implemented in StrolchComponents. Each component is registered via its Java interface on the agent and is bound to the life cycle of the agent. When the agent is started, these components can be retrieved and used to perform any number of functionalities. This is the preferred way to extend the Strolch agent. There are a number of components already implemented, e.g. the ServiceHandler which executes Services in a controlled fashion and can validate authorized access to these services.</p><p>No software product is complete without a system for authentication and authorization. Strolch implements this by using the Privilege framework which has been written by Robert von Burg. The standard ServiceHandler detects the existence of the PrivilegeHandler and then validates that the user has authorization to perform the service. This framework is implemented as its own Strolch component, thus can be retrieved at any time during execution to perform fine grained and special authorization validation.</p><h2 id=motivation>Motivation</h2><p>A question often asked is why create Strolch. What are its benefits in contrast to using Java SE with an OR-Mapper like Hibernate, or using Java EE on JBoss or Glassfish? Especially since many of the features existing in those stacks needed to be re-created in Strolch.</p><p>The first answer to this question is that those systems are often overly complicated and bloated. Java SE with Hibernate certainly is a viable option when it comes to being light-weightier but Hibernate, even though it is supposed to, often fails to truly help remove the need to really understand an RDBMS. Often enough Hibernate will just get in the way of the most important part of development: writing the business code. Being an OR-Mapper which is supposed to implement all the nitty-gritty details of an RDBMS system, Hibernate, and JPA for that matter, still often has the developer go back to understanding these details.</p><p>Strolch tries a different approach to persistence. Instead of writing pojos/entities, Strolch&rsquo;s model has the concept that each element&rsquo;s attributes are part of a composition pattern: each attribute is its own object and thus can be dynamically changed at runtime, but also makes persistence of such an element generic. Instead of having fixed attributes for a concrete class, these parameters are stored in a map and are accessed through the parameter&rsquo;s ID.</p><p>Assigning an ID to an attribute for accessing of course brings its own downsides, i.e. the parameter might simply not be there, when being accessed. This is certainly an issue that the developer must handle, when implementing a project using Strolch, but allows the developer to not need to worry about persistence, as this is generically handled.</p><p>Since the persistence is generically handled, and Strolch stays lightweight on its requirements at runtime, the developer can quickly get down to what is important for business value: Writing the business logic and the presentation layer. Here too Strolch tries to help the developer by bringing in concepts which are easy to follow: Use cases are implemented as Services, and re-usable business logic is put into Commands.</p><p>There will be reasons against using Strolch, as there will be against using the Java EE stack, or an OR-Mapper or even the Java ecosystem for that fact. Important is to note, that the concepts behind Strolch are nothing new, but have been implemented in at least two previous proprietary products. Since those products are not accessible to the public, it was decided that a re-implementation might be of use to the programming community at large.</p><p>Currently, there is at least one company using Strolch in a commercial project which helps drive Strolch&rsquo;s development and further motivates its existence.</p><p>Strolch is an open source project and licensed under the Apache License 2.0.</p><p>##Technology

This version 1.0.7 depends on Strolch version 1.6.100.\nEnjoy coding!\n"},{"uri":"https://strolch.li/blog/post-00015/","title":"Release of Strolch 1.6.100","tags":[],"description":"The 100. release of the 1.6 branch and a brand new website!","content":"Release of Strolch 1.6.100 The 100. Strolch release of the 1.6 branch and a brand new website!\n Ok, so Maven doesn\u0026rsquo;t exactly have 100 releases on it, but even though we have been quiet on public releases, Strolch has seen many refactorings, fixes, new features etc. over the past three years of its last release.\nSome notable changes:\n I18n Support for StrolchExceptions. Better performance for reports on large joins. Move to JDK 11+. Refactoring to use of Java 9 LocalDateTime and ZonedDateTime where applicable. Added Controllers for better execution handling. Significantly simplified the methods to change the model. Simpler methods to retrieve relationship entities. Updated most libraries to their latest versions. Added a DataArchiveHandler to archive entities. Added require password change feature, and storing of login and password change history LDAP integration Added session keep alive Search expression simplifications New TextParameter for when persisting large values with whitespace and special characters Basic Auth for REST APIs, if no UI needed for scripting Many additional fixes, tweaks and helper functions  Another new addition to the Strolch family is Strolch PLC. The Strolch PLC code allows one to use the same model but on a device acting as a soft PLC, e.g. a Raspberry Pi. This PLC code can then communicate using WebSockets with a Strolch instance, having quite seamless interaction with Activities which really shows the potential of using Strolch\u0026rsquo;s model in the shop floor.\nWe\u0026rsquo;ve been running the Strolch PLC in a mission critical shop floor application to control conveyors which are filled by a dispensing robot.\nSo, Strolch 1.6.100 is out the door, go ahead and try it out.\n"},{"uri":"https://strolch.li/blog/post-00014/","title":"Strolch Reports","tags":[],"description":"Strolch can do reports!","content":"Strolch Reports Strolch can do reports!\n A feature we haven\u0026rsquo;t written about yet is the report API. Strolch has it\u0026rsquo;s own API to generate reports of data, and since we have a generic model, we use Resource of type Report to define them.\nGo check out the documentation and then enjoy using this easy way to deliver the reports your peers require.\n"},{"uri":"https://strolch.li/blog/post-00013/","title":"Strolch Searches","tags":[],"description":"Strolch queries are deprecated!","content":"Strolch Searches Strolch queries are deprecated!\n Strolch has had once again many changes, and fixes etc. One important thing to note is that we have removed support for transactional mode and have rewritten how models are searched. Thus the search API was born.\nGo check out the Strolch Search documentation and then go rewrite your searches =)).\nStrolch tag 1.6.51 has all those juicy changes!\n"},{"uri":"https://strolch.li/blog/post-00012/","title":"Wow, the many changes!","tags":[],"description":"So many changes, and so long no update - not good!","content":"Wow, the many changes! So many changes, and so long no update - not good!\n Oh boy, have we forgotten to update you all on the latest awesome features in Strolch! There are over 123 commits since the last tag 1.3.0, so that alone merits a new blog post.\nCurrently the latest tag is 1.5.5, but this version is actually already quite old, as it was created on 31. January 2017 and there are 53 new commits ahead of the tag.\nEnough of all the commits, lets get to the new features:\n Added new generic report creator Added Activity.TimeOrdering and updated Model XSD Implemented State Model on Activity/Actions Implemented execution of Activities Implemented EventBasedExecutionHandler Added StrolchXmlParser to quickly parse from a file Add Activity.remove(String) to remove an element Refactored LockHandler to use Locator Added Activity.getActionsWithState(State) Moved *ToFlat and *FromFlat Json Visitors to strolch model Added StrolchElementQuery.internal() Added Parameter.clearValue() and list parameters use , as sep Json Tags are now in Tags.Json and are drinking camel-case Moved PrivilegeAddUserService to command, added tests Lots of JavaDoc updates Refactored code for REST Inspector to use gson Added inspector REST api for activities Inspector now has offset/limit for queries Added new StringMapArgument for StrolchServices Added missing activity observer calls in AbstractTransaction Added StringMapResult to use as a ServiceResult Removed many visitors and implemented proper visitor pattern\u0026hellip; Don\u0026rsquo;t log stack trace if certificate does not exist SmtpMailer now understands whitelists for override Fixed locator finding for Activity and Action Fixed undo logic for general commands  To summarize, execution and reporting are the two new features that make Strolch really awesome! We use execution to perform a number of actions on a remote device connected to a Strolch agent through WebSockets. This allows serial and parallel execution of actions and of course locking of concurrently used resources.\nIn an enterprise world reports can never be missed, so we needed an API to create reports. Of course that API was created in a way that all things are done in Strolch: generically. Thus a report is created as a Resource, defining the report object, columns and any relevant joins.\nAnd one of the really cool things is that we have started with a UI for Strolch. There is now an Inspector with which the entire data model of a running agent can be seen. This inspector is built using Polymer and WebComponents and thus can be easily embedded in your application.\nTo facilitate the authentication of a user for the inspector, an authentication component was created as well. And of course i18n can\u0026rsquo;t be forgotten, so there is a component for that too.\nTo simplify tasks in a web project, there is also a StrolchJs repository where certain Strolch specific things are handled e.g. querying the authenticated user\u0026rsquo;s roles etc.\nThe release of the next Strolch version isn\u0026rsquo;t defined yet, as we are internally building a project on all these changes and with the release 1.0.0 of that project (which will be soon), we shall perform the next release of Strolch.\nUntil then, happy coding!\n"},{"uri":"https://strolch.li/blog/post-00011/","title":"Strolch now on Maven Central","tags":[],"description":"Release Version 1.3.0 released and deployed to Maven Central","content":"Strolch now on Maven Central Release Version 1.3.0 released and deployed to Maven Central\n We have released a new version of Strolch so that you can now go and use the the latest features in Strolch.\nFurther we have now deployed Strolch to Maven Central, so it is easier than ever to use Strolch in your projects. No need to download first or use a special repository - just define the dependencies as you would any other dependency.\nSome of the new features:\n Marshallers for JSON Versioning built into Strolch Implemented password reset API for Privilege New Component MailHandler New ToFlatJsonVisitor for simple marshalling in REST APIs Added CRUD Commands and Services for Activities Further additional bugfixes  Strolch has also been moved to another organisation on GitHub, so if you\u0026rsquo;re compiling Strolch from source, please update your GIT remote configurations.\nHave fun using the latest and greatest version of Strolch!\n"},{"uri":"https://strolch.li/blog/post-00010/","title":"Versioning of objects","tags":[],"description":"Opt-In versioning of objects","content":"Versioning of objects Opt-In versioning of objects\n A major new feature has landed in Strolch. Now, using opt-in, it is possible to have all changes to the object model be versioned. This means that any change to Order, Resource or Activity is automatically versioned and one can then revert to this version later on.\nThis will make it far easier to implement undo operations in applications since it is an inherent part of the lifecycle of objects in Strolch.\nSince Strolch is supposed to be used also in small footprint hardware, this option is opt-in.\nA side affect of this new feature is that we have for the time being not ported the XML persistence layer. If this is required, then someone drop us a note and we\u0026rsquo;ll check on it.\nSo now go ahead and add \u0026lt;enableVersioning\u0026gt;true\u0026lt;/enableVersioning\u0026gt; to your Realm so that versioning is enabled.\n"},{"uri":"https://strolch.li/blog/post-00009/","title":"Release 1.2.0","tags":[],"description":"Release of Strolch 1.2.0","content":"Release 1.2.0 Release of Strolch 1.2.0\n A few months ago we informed of the soon to be released version 1.1.0. Well, we decided to jump to 1.2.0 because we did some refactorings. All the eitchnet projects have been melted into Strolch and thus now it\u0026rsquo;s all one nice package. This will result in simpler development and less constraints on APIs between the two projects.\nOther than that, not much changed, but we are continually working on Strolch, so go grab your latest copy and have fun coding!\n"},{"uri":"https://strolch.li/blog/post-00008/","title":"Strolch Update","tags":[],"description":"Long due update on Strolch development.","content":"Strolch Update Long due update on Strolch development.\n Although we have been rather quiet in the last couple of months, anyone viewing Strolch\u0026rsquo;s commit log, will see that we certainly didn\u0026rsquo;t halt Strolch development.\nWe have been hard at work, using Strolch in projects, which required many new features and fixes. The commit log shows as of today over 180 commits since the release tag 1.0.0.\nSome of the most exciting changes are:\n REST API to query model, incl. privilege management. JSON marshalling of all elements. Added Policies Added persisting of user sessions. New JavaScript based UI to view Strolch\u0026rsquo;s model. This is an initial version and more UI elements and functions will follow. Basic planning engine functionality.  Further new features and changes are:\n Implemented a REST API to the privilege management - Now users can be added, changed, etc. via call to the appropriate URL under ../strolch/privilege/*. Implemented a REST API to query the user sessions. Incl. invalidating sessions to forcefully logout users. Implemented a REST API to query Audits. Implemented REST API to query Orders, Resources and Activities/Actions Implemented REST API to update Resources and Orders from XML REST API to authenticate now adds a cookie, so authorization is much simpler. Added convenience methods in Service and Command to easily perform system user actions. Added audits for login/logout of users. Added audits for changes to privilege management. PostgreSQL persistence layer now uses HikariCP for connection pooling. Implemented a performance test project Added new Parameters of type IntegerList, FloatList and LongList. Added feature to ignore a realm on DB init. Implemented core planning functionality. Added strolch_minimal and strolch_minimal_rest projects to easily get started. Query API now has built in ordering. Added Policy to all root elements. Added new planning web app project. This is a test application for demoing the planning engine functionality of Strolch. Adding the persisting and reloading of user sessions, so that a new start of Strolch does not logout users. Implemented to JSON visitors for all root elements.  So, although we\u0026rsquo;ve been rather quiet on the blog and on social media, we have not been quiet in Strolch\u0026rsquo;s development. We are planning to release version 1.1.0 soon, so stay tuned!\n"},{"uri":"https://strolch.li/blog/post-00007/","title":"Activities: Beginning of the planning engine","tags":[],"description":"The ground work of the Strolch planning engine has been laid.","content":"Activities: Beginning of the planning engine The ground work of the Strolch planning engine has been laid.\n One of the core ideas in building Strolch was to create a planning engine. The planning engine would work in combination of Order objects representing customer orders, Resource objects representing machines, human resources, etc., and Activity/Action hierarchies defining a workflow.\nWith the latest couple of commits to Strolch we have now added Activities and a basic planning of Actions onto Resources. Activities have an ordered list of IActivityElement which allows creating an arbitrary deep tree structure of Activity and Action elements.\nAction objects have a list of IValueChange objects which define the start, end and further value changes over time on a referenced Resource. Thus planning an Activity is done by iterating the Activity hierarchy and for every Action selecting a relevant Resource and then then applying the changes of the Action on to the referenced TimeState on the Resource.\nThis implementation is currently very simple as it ignores all constraints which a Resource might have. In further development we shall implement a Violation model so that UIs can be built to visualize the over-use of Resources.\nIn even further steps we would then start implementing algorithms to not just apply the changes onto a Resource, but to actually search the Resource for time slots when the value changes would not violate any constraints applied to the resource.\nWe are very much looking forward to these new features. Stay tuned for your updates - even though they do take their time to arrive =).\n"},{"uri":"https://strolch.li/blog/post-00006/","title":"Strolch Documentation","tags":[],"description":"Any good software has some decent documentation explaining concepts, best practices and gives examples.","content":"Strolch Documentation Any good software has some decent documentation explaining concepts, best practices and gives examples.\n So this post is to announce that there is now a new page on Strolch\u0026rsquo;s website with a bit of documentation. This first documentation explains the Strolch runtime and some of the do and don\u0026rsquo;t in Strolch code.\nBear with us, writing documentation takes time and can be outdated quickly, so we will make an effort to keep everything up to date and add more documentation, but this is a start.\nSo go ahead and read the documentation , and if you haven\u0026rsquo;t already, also read the rest of the website which should give some more insight into the what, why and how of Strolch.\n"},{"uri":"https://strolch.li/blog/post-00005/","title":"Strolch Release 1.0.0","tags":[],"description":"Finally Version 1.0.0 of Strolch has been released and can be downloaded immediately.","content":"Strolch Release 1.0.0 Finally Version 1.0.0 of Strolch has been released and can be downloaded immediately.\n Before 1.0.0 could be released, some major changes were decided, all driven by the first big project using Strolch as its underlying stack. Those changes were minor, and really major, but should make Strolch better and was important for the first release.\nHere is a list of the most interesting changes:\n Java 8 - Strolch was ported to Java 8. This gives a lot of cool features: The stream API, lambdas, the new time API, etc. TX refactoring: Strolch transactions are instances of Closeable so that they are closed using a try-with-resource block in Java7. The change that was required was to not auto commit. Now a TX is read-only and one has to set the auto commit as the last statement. See this commit for more information. Added a tx.flush() to allow an implementation to flush part of a transaction, this feature is vital to perform parts of a transaction before deciding if the TX should be committed. Fixed the issue where data store mode CACHED performed TRANSACTIONAL queries, instead of staying in-memory. ParameterSelection.stringListSelection() uses a StringMatchMode instead of just equals() ParameterSelection.dateRangeSelection() uses a DateRange instead of just equals() Added the MigrationsHandler to use to perform code migrations of production data bases where data shouldn\u0026rsquo;t go lost. And many more\u0026hellip;  Strolch 1.1.0 is already in development and can also be downloaded from the download page. Here you can see the current change list on GitHub. For instance heavy work has been done to implement privilege management by adding a REST API.

As soon as we move Strolch to Java8, we will change this to use the Period class in the new Java8 date and time API.\nIn addition to the new parameter, a couple of other changes were made:\n 32c1785 [Major] Added Session timeout handling d55371e [Minor] fixed component version descriptions c1cdfbb [Bugfix] added missing cloning of StringSetTimedState in Resources 8f50a15 [Major] changed XML format of time value of TimedStates to be ISO8601 5fbbe50 [Bugfix] fix NPE when cloning Resources with no state vars b77f4b2 [New] added TimeVariable.clear()-method Updated sub-module ch.eitchnet.utils to 906d24d Updated sub-module ch.eitchnet.privilege to aa16887  So, Strolch 1.0.0-RC4 is out the door, go ahead and try it out.\n"},{"uri":"https://strolch.li/blog/post-00003/","title":"DB Initialization: Release 1.0.0-RC3","tags":[],"description":"Important feature Database Initialization added: Release of 1.0.0-RC3 which can be downloaded on the download page.","content":"DB Initialization: Release 1.0.0-RC3 Important feature Database Initialization added: Release of 1.0.0-RC3 which can be downloaded on the download page.\n When living continuous integration and continuous delivery, it is vital that things like database migrations and initialization are performed in a controlled, but automatic way.\nA Strolch-based application is using the PostgreSQL persistence layer. The implementation understands the concepts of migration, and validating the database schema, but currently a mechanism to automatically initialize the database with a minimal set of data was missing.\nMigrating a database for Strolch is mostly a one time thing. The object model in Strolch is quite static, so there is seldom a need to migrate the database. Domain specific changes, i.e. new Resources, or adding Parameters to Resources, is not a schema change. Thus, instead of going the way other frameworks go, e.g. Ruby on Rails, we built the data initialization right into the PersistenceHandler.\nNow if the PostgreSQL PersistenceHandler creates the schema, then it might also initialize the minimal set of data. For this to work, the PersistenceHandler checks if the flags allowSchemaCreation, allowSchemaDrop and allowDbInitOnSchemaCreate. If those flags are enabled, and the schema was created during initialization, then the database is also initialized with the contents of the XML file configured under key dataStoreFile of the relevant Realm.\nThe database initialization is done as a system user action which must have the name db_initializer. This is another fail-safe, so that on a production system, this user can simply be deleted.\nSo, Strolch 1.0.0-RC3 is out the door, go ahead and try it out.\n"},{"uri":"https://strolch.li/blog/post-00002/","title":"Release 1.0.0-RC2","tags":[],"description":"Scratch that RC1, here is the brand new 1.0.0-RC2 which can be downloaded on the download page.","content":"Release 1.0.0-RC2 Scratch that RC1, here is the brand new 1.0.0-RC2 which can be downloaded on the download page.\n So, as expected there were a few bugs, for instance the Strolch tutorial apps didn\u0026rsquo;t start, so now i fixed those and released an RC2.

To this affect we have now released version 1.0.0-RC1 which can be downloaded on the download page.","content":"Release 1.0.0-RC1 With the Go-Live of a Strolch-based application around the corner, it is time to release Version 1.0.0 of Strolch. To this affect we have now released version 1.0.0-RC1 which can be downloaded on the download page.\n Story Strolch as a component based software agent has been two years in the making. The concepts in Strolch have been taken from a proprietary planning, scheduling and controlling software agent, which was, and is been, used in industrial automation, logistics and production. Strolch was created to bring the concepts, which were working well for small teams to go-live with large projects in short to medium time-frames to the open source world.\nStrolch was completely rewritten using the key concepts of a parameterized object model and a component based agent but remembering which clutches the original implementation had, thus trying to eradicate those without bringing in new ones. It might not be perfect in version 1.0.0, but it is a starting point form which to carry on from.\nFeatures Strolch isn\u0026rsquo;t feature complete by a long shot, but it sure has got many features which make it useable in a concrete project, thus making sure it is not vaporware =)\nThe following is a list of key features, many of which were driven by concrete project requirements:\n Separate containers for models (mandates) Parameterized model with full CRUD for Resource and Order objects Timed values on Resources to map values by time Built-in versioning of model - configurable by Realm Transparent runtime modes: TRANSIENT, CACHED, TRANSACTIONAL* Service and Command pattern for reusing functionality XML File based persistence layer* PostgreSQL persistence layer* Querying using a fluent API Services to import and export a model to XML Integrated authentication and authorization to validate user privileges using Privilege Ready to use Observer pattern (currently) Read-only REST API to access the agent model remotely Configurable environments Opt-in audit trail (including read access, and the audits themselves) Basic components required to communicate with external devices using TCP/IP With the light weight implementation, where there are basically no third party libraries required for the normal runtime, Strolch has a minimal foot print which allows it to run on small devices for instance a BeagleBone Black. Using the in-memory mode, it is an easy feat to set up test environments with little to no further requirements than the JVM.  Future So what is planned for the future? Although Strolch has quite a few interesting features, it is by no way feature complete. The greatest wish is for Strolch to become a community driven platform, so many new features will arise in the future, but at least one major future feature which will be tackled in the near future and will certainly drive the next major release is a planning and scheduling engine using a Gantt chart to visualize the schedule.\nThe planning engine will use the timed values on Resources extensively to create a planning engine on which Workflows can be placed and allowing to detect violations and bottlenecks.\nAn extension of the planning of the scheduling engine will allow more than just placing Workflows on Resources, but actually searching groups of Resources for a time slot of when to place tasks. This will allow to use capacity constraints to plan and schedule workflows using different algorithms, and respecting calendars etc.\nFurther time will be spent on giving Strolch it\u0026rsquo;s own UI. Currently the idea is to use Google\u0026rsquo;s Polymer to implement the UI, thus creating reusable widgets that can be used in projects.\nTake it for a spin So, now the important part is for new users to start using Strolch for their own projects. Go ahead, check out the Downloads page for the latest release and then checkout the two tutorial applications to get yourself up to speed!\nDon\u0026rsquo;t hesitate to send us feedback or questions, we will be delighted to help you get your Strolch-based application up and running, or provide feedback to your concerns!\nDevelopers Robert von Burg Reto Breitenmoser Dr. Martin Smock\n*Currently Transactional mode is missing concrete implementation for querying for the XML persistence\n"},{"uri":"https://strolch.li/api/","title":"API","tags":[],"description":"","content":"Overview The Strolch API revolves around the StrolchTransaction object. The main concept is to implement your use cases in Service implementations. You open a transaction using the openTx(String)-method and then perform the use case by adding your Command instances to the transaction.\nTransactions are opened on a StrolchRealm. The realms are used to separate mandates in a single runtime instance of Strolch. Each realm has its own ResourceMap, OrderMap, ActivityMap instances from which the TX retrieves the elements.\nModel The Strolch model is implemented in the project li.strolch.model.\nThe Strolch model consists of three root level elements: Resource, Order and Activity. Each element has at least the following attributes:\n Id → the element\u0026rsquo;s id Name → the element\u0026rsquo;s name Type → the element\u0026rsquo;s type  Each root element can have any number of ParameterBag instances on it, which in turn can have any number of Parameters on it. Accessing these objects is always done by their IDs. Strolch root elements are always stored in the respective ElementMaps in their Strolch realm. Thus accessing a certain parameter from a Resource would look like this:\npublic class Test { public static void main(String[] args) { try (StrolchTransaction tx = openTx(realmName)) { Resource resource = tx.getResourceBy(\u0026#34;MyType\u0026#34;, \u0026#34;myResource\u0026#34;);

When configuring a Strolch runtime, realms are configured and for each realm the data store mode is set. Each realm has its own persistence configuration and can thus run in one of the 4 modes that the Strolch agent implements:\n EMPTY This is a transient data store mode, where no model changes are persisted, but they are only kept in memory. When the Strolch agent is started, this realm stays empty as no data is loaded. TRANSIENT This is the same as EMPTY, but with the difference that when the Strolch agent is started, an XML file is parsed and the in memory realm is populated with the elements parsed from that XML file. CACHED In this mode, all data is stored in memory, and any changes made are written back to the persistence layer. This allows for fast in-memory quries, but makes sure no data is lost when the agent is restarted.  Strolch Realms are also responsible for opening Transactions, as these are bound to the persistence layer configured for this realm. At runtime, a realm is then accessed from the ComponentContainer:\npublic class Example { public static void main(String[] args) { ComponentContainer container = getAgent().getContainer(); StrolchRealm realm = container.getRealm(StrolchConstants.DEFAULT_REALM); try (StrolchTransaction tx = realm.openTx()) { Resource resource = tx.getResourceBy(\u0026#34;TestType\u0026#34;, \u0026#34;MyTestResource\u0026#34;); } } } "},{"uri":"https://strolch.li/documentation/architecture/","title":"Architecture","tags":[],"description":"","content":"Architecture Birds View A Strolch agent\u0026rsquo;s architecture can be seen as a simple three-tier architecture. The presentation layer is mostly a web frontend, where the communication with the agent is done via REST API calls.\nThe agent itself implements the business logic using Services, Commands, Queries etc.\nThe agent can communicate with other 3rd systems using any API, where it is preferred to use JSON over REST.\nThe agent can use a standard RDBMS as a storage system, where currently DAOs have been implemented only for PostgreSQL. Should it be required, then any JDBC cabable RDBMS can be used, as no PostgreSQL specific SQL commands are used.\nThe following diagram helps visualize this:\nSquirrel View The following diagram shows a more detailed view of the architecture of a Strolch Agent:\nA Strolch agent consists of the following main parts:\n REST Endpoints → expose an API to access the Strolch agent outside of the Java VM Services and Commands → implements business logic Searches → implements specific queries against the Strolch model Components → Implements additional logic, which is best implement as a component. E.g. active components which have threads, etc. Realms → implements multi-tenant capabilities  In addition to the main parts, Strolch contains inherit capabilities, which gives Strolch unique features when compared to other Java Frameworks:\n Policies → Policies allow injecting different algorithms. All root elements can store Policy definitions, so that a service can delegate to a Policy and thus behave differently, depending on the element being accessed. Transactions → Transactions handle locking/unlocking of objects, updating the model and are the central API for the developer. Privileges → Strolch is user agnostic and any action, i.e. Service, Query, etc. is authorized against the authenticated user. Observers → modifications to the model are propagated to listeners using the observer pattern. Audits → Every access (read, modify) of the model are audited Versioning → modifications to objects are versioned and thus can be rolled back at a later time.

\u0026lt;/profiles\u0026gt; \u0026lt;/project\u0026gt; Now we need the rest of the directory structure:\n../strolch-bookshop/ - src/main/java/ - li/strolch/bookshop/ - \u0026lt;!-- java classes --\u0026gt; - src/main/resources/ - ENV.properties - appVersion.properties - logback.xml - src/main/webapp/WEB-INF/ - StrolchBootstrap.xml - runtime - config/ - PrivilegeConfig.xml - PrivilegeRoles.xml - PrivilegeUsers.xml - StrolchConfiguration.xml - StrolchPolicies.xml - data/ - StrolchModel.xsd - defaultModel.xml - templates.xml - temp/ A few notes to the resource files:\n The ENV.properties file is filtered by maven and the environment to load is written in it using the environment variable strolch.env. The appVersion.properties file is also filtered by maven and allows to reflect on the version of this app at runtime. The logback.xml file configures logging using SLF4j and Logback.  The StrolchBootstrap.xml file is used to configure Strolch\u0026rsquo;s environment and root directory. For a webapp it can be annoying to store Strolch\u0026rsquo;s configuration inside the webapp, which is why we can define an absolute path where the configuration is kept. In the following example we keep it in the root of the sources:\n\u0026lt;?xml version=\u0026#34;1.0\u0026#34; encoding=\u0026#34;UTF-8\u0026#34;?\u0026gt; \u0026lt;StrolchBootstrap\u0026gt; \u0026lt;env id=\u0026#34;dev.eitchpc\u0026#34; default=\u0026#34;true\u0026#34;\u0026gt; \u0026lt;root\u0026gt;/home/eitch/src/git/strolch-bookshop/runtime\u0026lt;/root\u0026gt; \u0026lt;environment\u0026gt;dev\u0026lt;/environment\u0026gt; \u0026lt;/env\u0026gt; \u0026lt;/StrolchBootstrap\u0026gt; Here we define two environments, but the both redefine the environment to dev. This is because we want this app to start on two different machines with different user home directories. See the profiles in the POM as to how these environments are activated using a environment property strolch.env.\nIn this next step we\u0026rsquo;ll create Strolch\u0026rsquo;s configuration at the location we defined in the StrolchBootstrap.xml file. Strolch\u0026rsquo;s configuration contains of three directories: config, data and temp. config contains static files which usually aren\u0026rsquo;t changed, data contains model files in XML format and temp is used at runtime for any temporary files, e.g. storing active sessions.\nThe configuration as well as the model has been described on Strolch\u0026rsquo;s documentation web page, we\u0026rsquo;ll just provide you with the files for the bookshop:\nPrivilegeConfig.xml\n\u0026lt;?xml version=\u0026#34;1.0\u0026#34;

A few notes on the configuration:\n  Note how there are three users. Jill is a user with currently no privileges as it\u0026rsquo;s role definition is empty. Admin can do everything, and the agent user is a system user which can also do everything.\n  There is one realm defined in the RealmHandler component which references the defaultModel.xml file in the data directory. This file then includes the currently still empty templates.xml file.\n  We have defined a global environment, but are using the dev environment. The dev environment includes the definitions in the global environment.\n  In PrivilegeConfig.xml we have enabled persistence of sessions, so you will be needing the unlimited JCE libraries for your JVM.\nWhen you restart the server, you don\u0026rsquo;t need to log back in, if your session is still alive.\n  In PrivilegeRoles.xml there seems to be a lot of boilerplate. One thing about a highly configurable system is that sometimes the configuration is bigger. In this case we have opted to have the configuration shown and not use default values which you don\u0026rsquo;t see, so that privilege access is clearly seen.\n  Your project is now ready to be imported into your favourite IDE. We have used both IntelliJ and Eclipse so this is up to you.\nNow that we have a configuration, it is time to have Strolch started when the WAR is deployed and started. In your IDE create a new class as follows:\nStartupListener.java\npackage li.strolch.bookshop.web; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; import javax.servlet.annotation.WebListener; import java.io.InputStream; import li.strolch.agent.api.StrolchAgent; import li.strolch.agent.api.StrolchBootstrapper; import li.strolch.utils.helper.StringHelper; import org.slf4j.Logger; import org.slf4j.LoggerFactory; @WebListener public class StartupListener implements ServletContextListener { private static final Logger logger = LoggerFactory.getLogger(StartupListener.class); private static final String APP_NAME = \u0026#34;Bookshop\u0026#34;; private StrolchAgent agent; @Override public void contextInitialized(ServletContextEvent sce) { logger.info(\u0026#34;Starting \u0026#34; + APP_NAME + \u0026#34;...\u0026#34;); long start = System.currentTimeMillis(); try { String boostrapFileName = \u0026#34;/WEB-INF/\u0026#34; + StrolchBootstrapper.FILE_BOOTSTRAP; InputStream bootstrapFile = sce.getServletContext().getResourceAsStream(boostrapFileName); StrolchBootstrapper bootstrapper = new StrolchBootstrapper(StartupListener.class); this.agent = bootstrapper.setupByBoostrapFile(StartupListener.class, bootstrapFile); this.agent.initialize(); this.agent.start(); } catch (Throwable e) { logger.error(\u0026#34;Failed to start \u0026#34; + APP_NAME + \u0026#34; due to: \u0026#34; + e.getMessage(), e); throw e; } long took = System.currentTimeMillis() - start; logger.info(\u0026#34;Started \u0026#34; + APP_NAME + \u0026#34; in \u0026#34; + (StringHelper.formatMillisecondsDuration(took))); } @Override public void contextDestroyed(ServletContextEvent sce) { if (this.agent != null) { logger.info(\u0026#34;Destroying \u0026#34; + APP_NAME + \u0026#34;...\u0026#34;); try { this.agent.stop(); this.agent.destroy(); } catch (Throwable e) { logger.error(\u0026#34;Failed to stop \u0026#34; + APP_NAME + \u0026#34; due to: \u0026#34; + e.getMessage(), e); throw e; } } logger.info(\u0026#34;Destroyed \u0026#34; + APP_NAME); } } Now configure your IDE to start the web project, and then once it has started, you should see the following in the logs:\nBookshop:dev All 8 Strolch Components started.

Further best practice is to use a parameters ParameterBag, with one or more parameters, modelling the fields. There is API support to not have to always type the parameters bag id. Note that in this example the Type of all the elements is Template. Strolch has API support to create a clone of these elements, so that they have a unique id, and the proper type for persistence. The Product element has three parameters: description, color and form. In this case they are all of type String. Further the relations ParameterBag defines the relationships, i.e. the product knows its articles. Note how the relation is first defined in a relations ParameterBag and that the Parameter has Interpretation=\u0026quot;Resource-Ref\u0026quot; Uom=\u0026quot;Product\u0026quot; attributes. Strolch has API support for this, making it trivial to retrieve a dependency. The Article element has two parameters description and barcode. Further it has a reference to its Product. The Order element doesn\u0026rsquo;t model the date and state fields as parameters, as these are inherently part of an Order element. The Order does define two references to customer and articles. A special case is the quantities ParameterBag. This bag of parameters is used to store the per article quantity for this order. With ParameterBags, you can eliminate the use of simple aggregate classes, as is commonly used in object-oriented programming. The Customer element models an address ParameterBag to store the address of a customer. Using a separate bag allows for further more direct fields to stored on the default parameters bag.  Now that we have a basic understanding of te model, it is of far more interest in how to create and interact with these elements at runtime. The following listing will perform simple operations:\npublic class Example { public static void main(String[] args) { // keep IDs for later use  String dafalganId; String dafalgan1Id; String dafalgan2Id;

\u0026lt;/Activity\u0026gt; Let\u0026rsquo;s explain a few things:\n  The Book entity is a Resource object and only contains the description and the current quantity in stock.\n  The Account entity is a Resource and contains the address and further details of the user, and with the user parameter the username is defined, thus referencing the real user.\n  The UserCart entity is a Resource and has a reference to the account Resource.\nNote how the reference is done using a StringParameter, where Interpretation, UOM and the value is set in a specific manner.\n   The UserCart entity is a Resource and references books using a special ParameterBag with the type set to Book, the actual type of the book entity. Each Parameter is of type Float and the ID of the parameter is the ID of the book, and the value is the quantity that the user would like to purchase.\nThere will only be one cart per user/account.\n  The PurchaseOrder entity is an Order object, and is basically a copy of the UserCart entity. This is the confirmed purchase order for the contents of a cart, and can then be used for reports on how much of which book was sold.\n  The FromStock entity is an Activity object and defines the process we will go through when delivering a purchase to a user.\nNote how the activity has a ParameterBag objectives with a duration parameter. This defines for this activity how long each Action should execute. This can be overridden in each Action and can help to plan how much effort goes into the delivering of each PurchaseOrder.\n Further note how the activity has three special actions (validate, package and send) on which a ResourceType and ResourceId are defined. Actions are always performed on a Resource, as the referenced Resource defines the behaviour of the action through defined Policy objects.\n   For each book which will be purchased, an Action will be created of type Consume. In the template this is defined by a template Action with the id Consume and will later be changed accordingly.\n  Since we are referencing resources from actions in the activity, we need to add these as well, but not as templates. They can be added to the defaultModel.xml file:\n\u0026lt;Resource Id=\u0026#34;validation\u0026#34; Name=\u0026#34;Validation Resource\u0026#34; Type=\u0026#34;Validation\u0026#34;\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;key:ValidationExecution\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ConfirmationPolicy\u0026#34; Value=\u0026#34;key:DefaultConfirmation\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; \u0026lt;Resource Id=\u0026#34;packaging\u0026#34; Name=\u0026#34;Packaging Resource\u0026#34; Type=\u0026#34;Packaging\u0026#34;\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;key:PackagingExecution\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ConfirmationPolicy\u0026#34; Value=\u0026#34;key:DefaultConfirmation\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; \u0026lt;Resource Id=\u0026#34;sending\u0026#34; Name=\u0026#34;Sending Resource\u0026#34; Type=\u0026#34;Sending\u0026#34;\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;key:SendingExecution\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ConfirmationPolicy\u0026#34; Value=\u0026#34;key:DefaultConfirmation\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; What should now be noted by these three new Resources is that they have Policy definitions:\n ExecutionPolicy → defines how an action on this resource is executed by referencing an ExecutionPolicy implementation. ConfirmationPolicy → defines behaviour to be performed on every state change of an action being performed on this resource by referencing an ConfirmationPolicy implementation.  Currently these resources reference policies which don\u0026rsquo;t exist. We will resolve this issue later, when we implement the execution of the activity.\nThis concludes the model definition. In the next step we\u0026rsquo;ll start creating services and commands for our model.\n"},{"uri":"https://strolch.li/plc/","title":"PLC","tags":[],"description":"","content":"Overview Using Strolch as a PLC has certain advantages and disadvantages. The following is a list of advantages:\n Same programming model and language for server and PLC PLC has the same privilege handling as in Strolch Simulating down to the PLC level is easily possible for easier testing of server logic  Of course using the Java language as a PLC has its limitations, we have manage to use it for customers and are satisfied with the result. What follows is a description in how to set up your own Strolch based PLC.\nCheckout the code at GitHub\nStrolch PLC is also deployed to Maven Central. Current version is 1.0.7.\nCurrently, we have the following topics of discussion:\n Architecture   Example Set-Up   "},{"uri":"https://strolch.li/tutorial/crud-book/","title":"CRUD Book","tags":[],"description":"","content":"Preparation Since Books are central to the bookshop, we\u0026rsquo;ll first create the CRUD REST API for them. The API will be as follows:\nGET ../rest/books?query=,offset=,limit= GET ../rest/books/{id} POST ../rest/books PUT ../rest/books/{id} DELETE ../rest/books/{id} Thus corresponding with querying, getting, creating, updating and removing of books. So let\u0026rsquo;s go ahead and add these REST APIs to our project.\nOur project is using JAX-RS 2.0 as the API and Jersey 2.x as the implementation, thus first we need to configure JAX-RS. Thus create the following class:\n@ApplicationPath(\u0026#34;rest\u0026#34;) public class RestfulApplication extends ResourceConfig { public RestfulApplication() { // add strolch resources  register(AuthenticationService.class); register(ModelQuery.class); register(Inspector.class); // add project resources by package name  packages(BooksResource.class.getPackage().getName()); // filters  register(AuthenticationRequestFilter.class, Priorities.AUTHENTICATION); register(AccessControlResponseFilter.class); register(AuthenticationResponseFilter.class); register(HttpCacheResponseFilter.class); // log exceptions and return them as plain text to the caller  register(StrolchRestfulExceptionMapper.class); // the JSON generated is in UTF-8  register(CharsetResponseFilter.class); RestfulStrolchComponent restfulComponent = RestfulStrolchComponent.getInstance(); if (restfulComponent.isRestLogging()) { register(new LoggingFeature(java.util.logging.Logger.getLogger(LoggingFeature.DEFAULT_LOGGER_NAME), Level.SEVERE, LoggingFeature.Verbosity.PAYLOAD_ANY, Integer.MAX_VALUE)); property(ServerProperties.TRACING, \u0026#34;ALL\u0026#34;); property(ServerProperties.TRACING_THRESHOLD, \u0026#34;TRACE\u0026#34;); } } } As we add new resources they will be automatically since we register the entire package.\nNow add the books resource class:\n@Path(\u0026#34;books\u0026#34;) public class BooksResource { } Search The first service we\u0026rsquo;ll add is to query, or search for the existing books. The API defines three parameters, with which the result can be controlled. The method can be defined as follows:\n@Path(\u0026#34;books\u0026#34;) public class BooksResource { @GET @Produces(MediaType.APPLICATION_JSON) public Response query(@Context HttpServletRequest request, @QueryParam(\u0026#34;query\u0026#34;) String queryS, @QueryParam(\u0026#34;offset\u0026#34;) String offsetS, @QueryParam(\u0026#34;limit\u0026#34;) String limitS) { // TODO  } } To fill this method we need a few things. First let\u0026rsquo;s define a constants class where we keep String constants which we used in the model file:\npublic class BookShopConstants { public static final String TYPE_BOOK = \u0026#34;Book\u0026#34;; } As this tutorial progresses, more and more constants will be added here. This class helps with two issues: Through the constants we can easily reason over where certain fields, and types are used and of course String literals in code are a rather bad thing.\nIn Strolch there are multiple way to access objects. The old way was using Queries, the new search API is much more fluent and easier to read and write. The search API, as well as the deprecated query API allows us to implement privilege validation and thus one should create corresponding classes for each type of search. Book entities are Resources, thus we will be creating a ResourceSearch. The search is for Resources of type Book thus the resulting search looks as follows:\npublic class BooksSearch\u0026lt;U\u0026gt; extends ResourceSearch\u0026lt;U\u0026gt; { public BookSearch() { types(TYPE_BOOK); } public BookSearch stringQuery(String value) { if (isEmpty(value)) return this; // split by spaces  value = value.trim(); String[] values = value.split(\u0026#34; \u0026#34;); // add where clauses for id, name and description  where(id().containsIgnoreCase(values) //  .or(name().containsIgnoreCase(values)) //  .or(param(BAG_PARAMETERS, PARAM_DESCRIPTION).containsIgnoreCase(values))); return this; } } Note how we added a special stringQuery(String)-method. This method defines where a search string entered by the user will be used to match a book. In this case for id, name and the description parameter.\nSo that our users can call this query, we must give them this as a privilege. This is done by adding the full class name to the PrivilegeRoles.xml file as follows:\n... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.search.StrolchSearch\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;Allow\u0026gt;internal\u0026lt;/Allow\u0026gt; \u0026lt;Allow\u0026gt;li.strolch.bookshop.search.BookSearch\u0026lt;/Allow\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;/Role\u0026gt; ...  Note: The internal allow value is a special privilege which is used internally when a service or something performs internal queries. This means that a service can perform a query for object to which the user might not have access, but without which the service could not be completed. We will use this in a later stage.\n Now we have all parts we need to implement the query method. The method will include opening a transaction, instantiating the search, executing the search, and returning the result:\n@Path(\u0026#34;books\u0026#34;) public class BooksResource { @GET @Produces(MediaType.APPLICATION_JSON) public Response query(@Context HttpServletRequest request, @QueryParam(\u0026#34;query\u0026#34;) String queryS, @QueryParam(\u0026#34;offset\u0026#34;) String offsetS, @QueryParam(\u0026#34;limit\u0026#34;) String limitS) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request .getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); int offset = StringHelper.isNotEmpty(offsetS) ? Integer.parseInt(offsetS) : 0; int limit = StringHelper.isNotEmpty(limitS) ? Integer.parseInt(limitS) : 0; // open the TX with the certificate, using this class as context  Paging\u0026lt;Resource\u0026gt; paging; try (StrolchTransaction tx = RestfulStrolchComponent.getInstance() .openTx(cert, getClass())) { // perform a book search  paging = new BookSearch() //  .stringQuery(queryS) //  .search(tx) //  .orderByName(false) //  .toPaging(offset, limit); } ResourceVisitor\u0026lt;JsonObject\u0026gt; visitor = new StrolchRootElementToJsonVisitor() .flat().asResourceVisitor(); return ResponseUtil.toResponse(paging, e -\u0026gt; e.accept(visitor)); } }  Note: We automatically transform the Resource objects to JSON using the StrolchElementToJsonVisitor. By calling the method .flat()-method we have a more compact JSON format. Paging is handled by a util class.\n The helper class ResponseUtil takes care of creating the JsonObject and the proper page. As a rule we use the format where we return two fields: msg is a dash if all is ok, otherwise an error message will be present. Data is always in the data field. This is just a personal taste, and can be changed to one\u0026rsquo;s own taste.\nGet We have all we need now to implement the GET method:\n@GET @Path(\u0026#34;{id}\u0026#34;) @Produces(MediaType.APPLICATION_JSON) public Response get(@Context HttpServletRequest request, @PathParam(\u0026#34;id\u0026#34;) String id) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // open the TX with the certificate, using this class as context  try (StrolchTransaction tx = RestfulStrolchComponent.getInstance().openTx(cert, getClass())) { // get the book  Resource book = tx.getResourceBy(BookShopConstants.TYPE_BOOK, id); if (book == null) return ResponseUtil.toResponse(Status.NOT_FOUND, \u0026#34;Book \u0026#34; + id + \u0026#34; does not exist!\u0026#34;); // transform to JSON  JsonObject bookJ = book.accept(new StrolchRootElementToJsonVisitor().flat()); // return  return ResponseUtil.toResponse(StrolchRestfulConstants.DATA, bookJ); } }  Note how we simply retrieve the book as a Resource from the TX. This is a good moment to familiarize yourself with the API of the StrolchTransaction. There are methods to retrieve elements, and also perform searches. We will use more of these methods later.\n Further it can be noted that a simple retrieval isn\u0026rsquo;t validated against the user\u0026rsquo;s privileges, the user is authenticated, which is enough for the moment.\nCreate To create a new book we need to implement a Service. This service will be called CreateBookService. A Service always has a ServiceArgument and a ServiceResult. Our service will use the JsonServiceArgument and the JsonServiceResult. The implementation of the POST method is as follows:\n@POST @Produces(MediaType.APPLICATION_JSON) public Response create(@Context HttpServletRequest request, String data) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // parse data to JSON  JsonObject jsonData = JsonParser.parseString(data).getAsJsonObject(); // instantiate the service with the argument  CreateBookService svc = new CreateBookService(); JsonServiceArgument arg = svc.getArgumentInstance(); arg.jsonElement = jsonData; // perform the service  ServiceHandler serviceHandler = RestfulStrolchComponent.getInstance().getServiceHandler(); JsonServiceResult result = serviceHandler.doService(cert, svc, arg); // return depending on the result state  if (result.isOk()) return ResponseUtil.toResponse(StrolchRestfulConstants.DATA, result.getResult()); return ResponseUtil.toResponse(result); }  Note: We return the created object again as JSON in its own data field.\n The service is implemented as follows:\npublic class CreateBookService extends AbstractService\u0026lt;JsonServiceArgument, JsonServiceResult\u0026gt; { @Override protected JsonServiceResult getResultInstance() { return new JsonServiceResult(); } @Override public JsonServiceArgument getArgumentInstance() { return new JsonServiceArgument(); } @Override protected JsonServiceResult internalDoService(JsonServiceArgument arg) throws Exception { // open a new transaction, using the realm from the argument, or the certificate  Resource book; try (StrolchTransaction tx = openArgOrUserTx(arg)) { // get a new book \u0026#34;instance\u0026#34; from the template  book = tx.getResourceTemplate(BookShopConstants.TYPE_BOOK); // map all values from the JSON object into the new book element  book.accept(new FromFlatJsonVisitor(arg.jsonElement.getAsJsonObject()).ignoreBag(BAG_RELATIONS)); // save changes  tx.add(book); // notify the TX that it should commit on close  tx.commitOnClose(); } // map the return value to JSON  JsonObject result = book.accept(new StrolchElementToJsonVisitor().flat()); // and return the result  return new JsonServiceResult(result); } }  Note: For the authenticated user to be able to perform this service, we must add it to their privileges:\n ... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; ... \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;Allow\u0026gt;li.strolch.bookshop.service.CreateBookService\u0026lt;/Allow\u0026gt; \u0026lt;/Privilege\u0026gt; ... \u0026lt;/Role\u0026gt; ... Update Updating of a book is basically the same as the creation, we just use PUT, verify that the book exists and give the user the privilege.\nPUT Method:\n@PUT @Path(\u0026#34;{id}\u0026#34;) @Produces(MediaType.APPLICATION_JSON) public Response update(@Context HttpServletRequest request, @PathParam(\u0026#34;id\u0026#34;) String id, String data) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // parse data to JSON  JsonObject jsonData = JsonParser.parseString(data).getAsJsonObject(); // instantiate the service with the argument  UpdateBookService svc = new UpdateBookService(); JsonServiceArgument arg = svc.getArgumentInstance(); arg.objectId = id; arg.jsonElement = jsonData; // perform the service  ServiceHandler serviceHandler = RestfulStrolchComponent.getInstance().getServiceHandler(); JsonServiceResult result = serviceHandler.doService(cert, svc, arg); // return depending on the result state  if (result.isOk()) return ResponseUtil.toResponse(StrolchRestfulConstants.DATA, result.getResult()); return ResponseUtil.toResponse(result); } Update Service:\npublic class UpdateBookService extends AbstractService\u0026lt;JsonServiceArgument, JsonServiceResult\u0026gt; { @Override protected JsonServiceResult getResultInstance() { return new JsonServiceResult(); } @Override public JsonServiceArgument getArgumentInstance() { return new JsonServiceArgument(); } @Override protected JsonServiceResult internalDoService(JsonServiceArgument arg) throws Exception { // verify same book  DBC.PRE.assertEquals(\u0026#34;ObjectId and given Id must be same!\u0026#34;, arg.objectId, arg.jsonElement.getAsJsonObject().get(Json.ID).getAsString()); // open a new transaction, using the realm from the argument, or the certificate  Resource book; try (StrolchTransaction tx = openArgOrUserTx(arg)) { // get the existing book  book = tx.getResourceBy(BookShopConstants.TYPE_BOOK, arg.objectId, true); // map all values from the JSON object into the new book element  book.accept(new FromFlatJsonVisitor(arg.jsonElement.getAsJsonObject()).ignoreBag(BAG_RELATIONS)); // save changes  tx.update(book); // notify the TX that it should commit on close  tx.commitOnClose(); } // map the return value to JSON  JsonObject result = book.accept(new StrolchElementToJsonVisitor().flat()); // and return the result  return new JsonServiceResult(result); } } Privilege\n... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; ... \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; ... \u0026lt;Allow\u0026gt;li.strolch.bookshop.service.UpdateBookService\u0026lt;/Allow\u0026gt; ... \u0026lt;/Privilege\u0026gt; ... \u0026lt;/Role\u0026gt; ... Remove To remove a book, we need a DELETE method, a remove service and the associated privilege.\nDELETE Method:\n@DELETE @Path(\u0026#34;{id}\u0026#34;) @Produces(MediaType.APPLICATION_JSON) public Response update(@Context HttpServletRequest request, @PathParam(\u0026#34;id\u0026#34;) String id) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // instantiate the service with the argument  RemoveBookService svc = new RemoveBookService(); StringServiceArgument arg = svc.getArgumentInstance(); arg.value = id; // perform the service  ServiceHandler serviceHandler = RestfulStrolchComponent.getInstance().getServiceHandler(); ServiceResult result = serviceHandler.doService(cert, svc, arg); // return depending on the result state  return ResponseUtil.toResponse(result); } Remove Service:\npublic class RemoveBookService extends AbstractService\u0026lt;StringServiceArgument, ServiceResult\u0026gt; { @Override protected ServiceResult getResultInstance() { return new ServiceResult(); } @Override public StringServiceArgument getArgumentInstance() { return new StringServiceArgument(); } @Override protected ServiceResult internalDoService(StringServiceArgument arg) throws Exception { // open a new transaction, using the realm from the argument, or the certificate  try (StrolchTransaction tx = openArgOrUserTx(arg)) { // get the existing book  Resource book = tx.getResourceBy(BookShopConstants.TYPE_BOOK, arg.value, true); // save changes  tx.remove(book); // notify the TX that it should commit on close  tx.commitOnClose(); } // and return the result  return ServiceResult.success(); } } Privilege:\n... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; ... \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; ... \u0026lt;Allow\u0026gt;li.strolch.bookshop.service.RemoveBookService\u0026lt;/Allow\u0026gt; ... \u0026lt;/Privilege\u0026gt; ... \u0026lt;/Role\u0026gt; ... Notes One should now see a pattern emerge:\n The REST API delegates to the Services, or Searches, with the exception of the retrieval of a single object by id. Services should do initial validation of the input. Not much validation was done here, but more could be done. Commands are reusable objects to perform recurring work. Searches and Services are privileged actions for which a user must have the privilege to perform the action.  The book services are quite simple, but as more requirements arise, it should be easy to implement them in the service layer. Thus should a service be required to be performed by an integration layer, then they can simply call the services, since the input is defined and validation is done there (i.e. NOT in the REST API).\nThis concludes the CRUD of books.\n"},{"uri":"https://strolch.li/documentation/do-and-donts/","title":"Do and Don&#39;t","tags":[],"description":"","content":"This page discusses things you should and shouldn\u0026rsquo;t do when using Strolch The following is a simple list of do\u0026rsquo;s and don\u0026rsquo;ts:\n  1 Service per use-case, should mostly delegate to Commands.\n  Commands implement use-cases or parts of it, and are thus reusable.\n  Subclass ResourceSearch, OrderSearch and ActivitySearch when implementing use-case specific search - this allows privilege checking.\n  One Transaction at a time - no TX inside of another TX.\n  Commands are added to TXs and performed on close: tx.addCommand(Command) and then tx.commitOnClose()\n  Only access ElementMaps if really no other way, mostly use tx.get*By(), tx.findBy() and searches - if a specific get is missing, then add the method to StrolchTransaction and send a pull request!\n  Use tx.stream*() methods to iterate over all elements, if you don\u0026rsquo;t want to use a search.\n  Don\u0026rsquo;t write logic in REST API beans.

The configuration are files located in the ..config/ folder, and the model are files located in the ../data folder.\nIn an absolute minimal configuration, the Strolch runtime requires the following folder structure:\n ../config/  ../StrolchConfiguration.xml → configures the Strolch agent ../PrivilegeConfig.xml → configures user management ../PrivilegeUsers.xml → contains the users in an XML based user management file ../PrivilegeRoles.xml → contains the roles and privileges in an XML based user management    StrolchConfiguration.xml The StrolchConfiguration.xml file configures the Strolch agent. The StrolchConfiguration.xml defines the following:\n \u0026lt;StrolchConfiguration\u0026gt; root element \u0026lt;env id=\u0026quot;xxx\u0026quot;\u0026gt; different environments with the possibility of having a global environment for configuration valid in multiple environments.  \u0026lt;Runtime\u0026gt; element which defines the agents name and a few other properties e.g. locale and verbose: \u0026lt;applicationName\u0026gt; the agent\u0026rsquo;s name \u0026lt;Properties\u0026gt;  \u0026lt;locale\u0026gt; the agent\u0026rsquo;s internal locale for log messages etc. \u0026lt;verbose\u0026gt; the logging level for some internal logging. (Logging is mostly done using log4j over slf4j)   \u0026lt;Component\u0026gt; elements for each component used in the agent. A component is configured by defining the following child elements:   \u0026lt;name\u0026gt; the name of the component, use when defining dependencies between components. The name is mostly set to the simple name of the interface of the component\n  \u0026lt;api\u0026gt; the full class name to the interface of the component. During runtime this interface will be used to access the component e.g.:\nServiceHandler svcHandler = agent.getContainer().getComponent(ServiceHandler.class);\n  \u0026lt;impl\u0026gt; the full class name of the concrete implementation of the component. During initialization this class will be instantiated and registered under the component name and interface. This class must extend the class li.strolch.agent.api.StrolchComponent\n  \u0026lt;depends\u0026gt; any number of these elements, where the content is the name of another component, on which this component depends. Depending components are initialized and started after the component they depend on and are stopped and destroyed before\n  \u0026lt;Properties\u0026gt;\n  \u0026lt;...\u0026gt; any number of properties which the component requires. The element\u0026rsquo;s name will be the key with which the value can be accessed at runtime.\n      When a property is missing, and the component has a hard coded default value, then when the component is initialized, the use of the default value and its key is logged. This makes it easy to see which new properties can be configured. Should the component not define a default value, then the component will thrown an exception on initialization. In this case it can be a good moment to read the JavaDoc (or source code) for the component in question to see how it is configured.\n Privilege Configuration In Strolch authentication and authorization is baked in. To open a transaction, and thus access the Strolch model, a Certificate object is required, which means the user has been authenticated and possibly authorized.\nThe PrivilegeConfig.xml defines the following:\n \u0026lt;Privilege\u0026gt; root element  \u0026lt;Container\u0026gt; configures the individual Privilege components  \u0026lt;Parameters\u0026gt; base configuration properties for Privilege \u0026lt;EncryptionHandler\u0026gt; configures the hashing algorithms and other encryption specific configuration \u0026lt;PersistenceHandler\u0026gt; configures the persistence of the roles and users \u0026lt;UserChallengeHandler\u0026gt; configures a challenge handler so that a user can reset their password. The default challenge handler is the li.strolch.privilege.handler.MailUserChallengeHandler which sends a challenge to the user\u0026rsquo;s defined e-mail address. \u0026lt;SsoHandler\u0026gt; the SSO Handler is used to implement a SingleSignOn and can be used to start a session using a LDAP token, etc. There is no default implementation as this is project specific.   \u0026lt;Policies\u0026gt; configures the available privilege policies at runtime, the name is referenced from the model file    The PrivilegeUsers.xml and PrivilegeRoles.xml define the users and roles and is used when in PrvilegeConfig.xml the PersistenceHandler is set to ch.eitchnet.privilege.handler.XmlPersistenceHandler:\n \u0026lt;Users\u0026gt; configures all users  \u0026lt;User\u0026gt; configures a specific user  \u0026lt;Firstname\u0026gt; configures a user\u0026rsquo;s first name \u0026lt;Lastname\u0026gt; configure a user\u0026rsquo;s last name \u0026lt;State\u0026gt; configures the user\u0026rsquo;s state, see li.strolch.privilege.model.UserState \u0026lt;Locale\u0026gt; configure the user\u0026rsquo;s locale \u0026lt;Roles\u0026gt; configures the user\u0026rsquo;s roles  \u0026lt;Role\u0026gt; adds a role to the user \u0026lt;Properties\u0026gt; configures user specific properties. What properties are used is not specified and is dependent on the concrete agent  \u0026lt;Property\u0026gt; defines a single property       \u0026lt;Roles\u0026gt; configures all roles  \u0026lt;Role\u0026gt; configures a specific role  \u0026lt;Privilege\u0026gt; configures a specific privilege for this role  \u0026lt;AllAllowed\u0026gt; if set to true, then defines that all values associated with this privilege are allowed \u0026lt;Allow\u0026gt; defines one allowed value for this privilege \u0026lt;Deny\u0026gt; defines one denied value for this privilege          Implementing a StrolchComponent Implementing a strolch component requires an interface, which defines the component\u0026rsquo;s API and a concrete class which implements the interface and extends the class StrolchComponent.\nThe StrolchComponent class adds the state model to the class, which transitions as follows:\nUNDEFINED =\u0026gt; SETUP =\u0026gt; INITIALIZED =\u0026gt; STARTED \u0026lt;=\u0026gt; STOPPED =\u0026gt; DESTROYED\nComponents can switch between STARTED and STOPPED, but once DESTROYED no further state change is possible. The component\u0026rsquo;s state is changed by changes to the agent\u0026rsquo;s lifecycle.\nA component\u0026rsquo;s state is changed by a call to the appropriate method on the component, override the methods as necessary. Note that it is good practice that the initialize()-method is used to get all the configuration properties, and that they should there be evaluated and that the method so return quickly. The start()-method is called after the agent\u0026rsquo;s initialization and should be where additional threads are started. Correctly implementing these methods allows to quickly detect a wrongly configured agent, which might take longer to start for whatever reason.\nThe following shows a basic implementation of a component on the basis of a post initializer (a component which performs some actions in its start()-method which should be done after everything else is started in the agent).\npublic class SimplePostInitializer extends StrolchComponent implements PostInitializer { public SimplePostInitializer(ComponentContainer container, String componentName) { super(container, componentName); } @Override public void initialize(ComponentConfiguration configuration) { // do some initialization, validate configuration values, etc.  // now call super, to update state  super.initialize(configuration); } @Override public void start() { // start any threads, or perform long running start work  // now call super, to update state  super.start(); } @Override public void stop() { // stop threads and timers, but be ready to start again  // now call super, to update state  super.stop(); } @Override public void destroy() { // destroy this component, release all resources and don\u0026#39;t worry about  // being called to start again now call super, to update state  super.destroy(); } } The new component would then be registered in the StrolchConfiguration.xml as follows:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;...\u0026#34;\u0026gt; ... \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;SimplePostInitializer\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.agent.api.PostInitializer\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.documentation.SimplePostInitializer\u0026lt;/impl\u0026gt; \u0026lt;/Component\u0026gt; ... \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; And can be access at runtime using:\nPostInitializer postInitializer = getContainer().getComponent(PostInitializer.class); Starting the agent When a Strolch runtime is started, then the root path to the runtime configuration must be passed. In Java this is done by calling:\nStrolchAgent agent = new StrolchAgent(); agent.setup(environment, rootPath); agent.initialize(); agent.start(); In Servlet 3.0 applications one would implement the javax.servlet.ServletContextListener interface, add the @WebListener annotation to the class and in the contextInitialized()-method start Strolch:\nString realPath = sce.getServletContext().getRealPath(\u0026#34;/WEB-INF\u0026#34;); String environment = StrolchEnvironment.getEnvironmentFromEnvProperties(pathF); this.agent = new StrolchAgent(); this.agent.setup(environment, new File(realPath)); this.agent.initialize(); this.agent.start(); "},{"uri":"https://strolch.li/tutorial/","title":"Tutorial","tags":[],"description":"","content":"Let\u0026rsquo;s build a bookshop!

A PlcGwService instance will be notified and can then decide on an action. In an execution model with Activities, the PlcNotificationListener interface can be implemented, or the PlcExecutionPolicy can be directly extended.\nOn the PLC side, the PlcGwClientHandler is optional if no agent is required. The PlcHandler initializes the model and connections. The Plc class is Strolch agnostic and manages the connections and notifies PlcListener instances on changes coming from the underlying connections. The PlcService implementations implement business logic, and can also be notified on updates from connections.\n"},{"uri":"https://strolch.li/documentation/realms/","title":"Realms","tags":[],"description":"","content":"Realms Realms implement multi-tenant capabilities. A Strolch agent can have an arbitrary number of realms configured and each realm has its own persistence configuration, allowing to separate mandates completely.\nA realm can run in one of the following modes:\n EMPTY This is a transient data store mode, where no model changes are persisted - they are only kept in memory. When the Strolch agent is started, this realm is empty as no data is loaded. TRANSIENT This is the same as EMPTY, but with the difference that when the Strolch agent is started, a model file is parsed and the in-memory realm is populated with the elements parsed from the model file. CACHED In this mode, all data is stored in-memory, and any changes made are written back to the persistence layer. This allows for fast in-memory qeuries, but makes sure no data is lost when the agent is restarted.  Realms are mostly hidden from a developer as a StrolchTransaction exposes all important operations needed to access Strolch objects. A developer will however need to configure the realms for their specific project. If the project only requires one realm, then the defaultRealm can be used, where the developer only is required to configure the mode and any relevant model file.\nIf the mode is CACHED, then the PersistenceHandler component is required to be configured, so that the DAOs know how to access the underlying database.\nThe configuration in the StrolchConfiguration.xml file is as follows:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;dev\u0026#34;\u0026gt; ... \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;RealmHandler\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.agent.api.RealmHandler\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.agent.impl.DefaultRealmHandler\u0026lt;/impl\u0026gt; \u0026lt;depends\u0026gt;PrivilegeHandler\u0026lt;/depends\u0026gt; \u0026lt;!-- if CACHED: --\u0026gt; \u0026lt;!--depends\u0026gt;PersistenceHandler\u0026lt;/depends--\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;!-- one of EMPTY, TRANSIENT, CACHED--\u0026gt; \u0026lt;dataStoreMode\u0026gt;TRANSIENT\u0026lt;/dataStoreMode\u0026gt; \u0026lt;dataStoreFile\u0026gt;StrolchModel.xml\u0026lt;/dataStoreFile\u0026gt; \u0026lt;/Properties\u0026gt; \u0026lt;/Component\u0026gt; ... \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; Multi-Realm A multi-realm configuration would be as follows.\nNote how the defaultRealm is still enabled, and has its configuration as before.

An agent is basically a container for classes extending StrolchComponent with a life cycle. These classes mostly implement an interface which describes the operations that are supported by the component.\nThe following represents a list of the most used components:\n RealmHandler: li.strolch.agent.impl.DefaultRealmHandler PrivilegeHandler: li.strolch.runtime.privilege.DefaultStrolchPrivilegeHandler EnumHandler: li.strolch.runtime.query.enums.DefaultEnumHandler PolicyHandler: li.strolch.policy.DefaultPolicyHandler ServiceHandler: li.strolch.service.api.DefaultServiceHandler StrolchSessionHandler: li.strolch.rest.DefaultStrolchSessionHandler PersistenceHandler: multiple implementations PostInitializer: project specific implementation MailHandler: li.strolch.handler.mail.SmtpMailHandler  A component has a life-cycle, which is governed by the Agent\u0026rsquo;s own life-cycle. The life-cycle is as follows:\nsetup -\u0026gt; initialize -\u0026gt; start \u0026lt;-\u0026gt; stop -\u0026gt; destroy The setup step is used to instantiate the component, the initialize step is used to validate configuration parameters, and the run step is used to start the component, i.e. start threads, etc. The stop step stops these threads and also allows the component to be started again. The destroy step destroys the instance and makes it unusable anymore, i.e. shutdown of the agent.\nEach component has its own configuration parameters. A component is registered in the StrolchConfiguration.xml file with a\n name api class name implementation class name configuration parameters any required dependencies  The dependencies is an important feature as the dependencies of a component are always started before the actual component.\nExample Component implementation and configuration By example of the MailHandler we shall show how a strolch component would be implemented.\nFirst define an interface:\npublic interface MailHandler { void sendMail(String subject, String text, String recipient); } Then implement a concrete MailHandler:\npublic class SmtpMailHandler extends StrolchComponent implements MailHandler { // TODO instance fields with configuration properties to send the mail  public SmtpMailHandler(ComponentContainer container, String componentName) { super(container, componentName); } @Override public void initialize(ComponentConfiguration configuration) throws Exception { // TODO store any properties needed from the configuration  super.initialize(configuration); } @Override public void sendMail(String subject, String text, String recipient) { // TODO send the e-mail using SMTP, or send asynchronously  } } Now that the component is written, it must be registered on the component, so that it is loaded when the agent is started. For this the StrolchConfiguration.xml file must be modified to include a component element:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;dev\u0026#34;\u0026gt; ... \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;MailHandler\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.handler.mail.MailHandler\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.handler.mail.SmtpMailHandler\u0026lt;/impl\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;username\u0026gt;test\u0026lt;/username\u0026gt; \u0026lt;password\u0026gt;test\u0026lt;/password\u0026gt; \u0026lt;hostName\u0026gt;localhost\u0026lt;/hostName\u0026gt; ... \u0026lt;/Properties\u0026gt; \u0026lt;/Component\u0026gt; ... \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; Now when the agent is started, the component can be retrieved and used. E.g from inside a Service:\npublic class MyService extends AbstractService\u0026lt;ServiceArgument, ServiceResult\u0026gt; { @Override protected ServiceResult internalDoService(ServiceArgument arg) throws Exception { MailHandler mailHandler = getComponent(MailHandler.class); mailHandler.sendMail(\u0026#34;My Subject\u0026#34;, \u0026#34;Hello World\u0026#34;, \u0026#34;test@test.ch\u0026#34;); } } "},{"uri":"https://strolch.li/documentation/services-and-commands/","title":"Services and Commands","tags":[],"description":"","content":"Services and Commands Services are written to implement a specific use-case.

The use-case can be abstract e.g., AddResourceService or very specific e.g. CreatePatientService.\nShould the use-case be re-usable in different scenarios, then commands should implement the logic, and the services should then execute the commands. E.g. The CreatePatientService would use a CreatePatientResourceCommand and then use an AddResourceCommand in a single transaction, so that the task of creating the actual Patient Resource can be re-used somewhere else.\nServices extend the abstract class AbstractService and then implement the method internalDoService(ServiceArgument).

Strolch searches are implemented using the StrolchSearch class and one of its concrete implementations: ResourceSearch, OrderSearch, ActivitySearch.\nA Strolch element always has two identifiers: Type and Id. The type is important as it classifies an element. So if a car and a house would be modelled in Strolch, then those would both be a Resource, but one of type Car and the other of type House. Both would have different parameters. Thus when searching for objects, the first thing to do is define the type of object being searched.\nThe Strolch search API is very expressive and offers multiple ways to perform the same search. The search API consists of three components: The search classes, the search expressions and the search predicates. The concept was taken from the Apache Camel project.\nThere are four main search classes:\n RootElementSearch - search for any of Resource, Order or Activity elements ResourceSearch - search for Resources OrderSearch - search for Orders ActivitySearch - search for Activities  No search is useful without a where clause, which are called search expressions. When writing a search, there are multiple ways to add such where clauses. Either\n override the define()-method in your sub class and add the where clauses by calling the where() method, or define special methods on the class e.g. byColor() which also calls the where()-method to add a search expression, or directly call the where()-method after instantiating a search.  When extending the class, then the search expressions are available as methods on the super class, otherwise you can statically import them from ExpressionsSupport .\nAnd of course a where clause needs operators, which are called search predicates. Just as search expressions are available in sub classes, so are search predicates and can also be statically imported through PredicatesSupport .\nExamples of search expressions with search predicates follow:\nResourceSearch search=new ResourceSearch(); // predicate either as parameter, or chained search.where(id().isEqualTo(\u0026#34;myId\u0026#34;)); search.where(id(isEqualTo(\u0026#34;myId\u0026#34;))); // negating search.where(id(isEqualTo(\u0026#34;myId\u0026#34;)).not()); search.where(param(\u0026#34;bagId\u0026#34;,\u0026#34;paramId\u0026#34;).isIn(Arrays.asList(\u0026#34;red\u0026#34;,\u0026#34;blue\u0026#34;,\u0026#34;green\u0026#34;))); search.where(paramNull(\u0026#34;bagId\u0026#34;,\u0026#34;paramId\u0026#34;))); // boolean operations search.where(id(isEqualTo(\u0026#34;myId\u0026#34;)) // \t.or(name(isEqualTo(\u0026#34;myName\u0026#34;)))); Note how the predicates can be chained to the search expression, or passed as a parameter to the expression.\nIn addition to using predefined search search expressions, one can also just pass a lambda expression which performs a custom filter:\npersonSearch.where(person -\u0026gt; person.getName().length() == 3); See the StrolchSearchTest for many ways in which you can implement tests.\nNote that strolch searches requires privileges, thus when you use a strolch search, add it to the role of the user in PrivilegeRoles.xml:\n \u0026lt;Privilege name=\u0026#34;li.strolch.search.StrolchSearch\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;Allow\u0026gt;internal \u0026lt;/Allow\u0026gt; \u0026lt;!-- internal used for when the search is done in an internal service --\u0026gt; \u0026lt;Allow\u0026gt;li.strolch.bookshop.search.BookSearch\u0026lt;/Allow\u0026gt; \u0026lt;/Privilege\u0026gt; "},{"uri":"https://strolch.li/documentation/queries/","title":"Queries","tags":[],"description":"","content":"Queries The Query API is deprecated and the search API should be used instead.\n As is custom for every framework, querying the model must be possible. Strolch queries are implemented using the StrolchQuery interface and one of its concrete implementations: ResourceQuery, OrderQuery, ActivityQuery.\nA Strolch element always has two identifiers: Type and Id. The type is important as it classifies an element. So if a car and a house would be modelled in Strolch, then those would both be a Resource, but one of type Car and the other of type House. Both would have different parameters.\nThus one of the inputs for every query is it\u0026rsquo;s type, which is defined as the navigation. It is said that we navigate to the Cars, or Houses. Thus when instantiating a ResourceQuery, pass the navigation to the type of Resource as well. Same applies for Orders and Activities.\nFurther input for a StrolchQuery are the selections. These selections get translated into RDBMS WHERE clauses. Selections support boolean operations thus allowing for complex querying.\nStrolchQueries also support Ordering and object transformation. Following classes provide the most used scenarios:\n OrderById OrderByName OrderByParameter *ToDomVisitor *ToSaxVisitor *ToJsonVisitor *ToFlatJsonVisitor  Example: Query all resources of type Car:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.withAny(); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car, order by Name and transform to JSON:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;JsonObject\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;, new ResourceToJsonVisitor(), new OrderByName()); query.withAny(); List\u0026lt;JsonObject\u0026gt; cars = tx.doQuery(query); } the previous example can also be written as follows:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;JsonObject\u0026gt; query = new ResourceQuery\u0026lt;\u0026gt;(); query.setNavigation(new StrolchTypeNavigation(\u0026#34;Car\u0026#34;)); query.setResourceVisitor(new ResourceToJsonVisitor()); query.withAny(); List\u0026lt;JsonObject\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car with color blue:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.with(ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es())); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car which are not blue:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.not(ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es())); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car with color blue or yellow:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.or().with( ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es()), ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;yellow\u0026#34;, StringMatchMode.es())); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car with color blue or yellow owned by Jill:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); StringParameterSelection owner = ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;owner\u0026#34;, \u0026#34;Jill\u0026#34;, StringMatchMode.es()); OrSelection colors = new OrSelection().with( ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es()), ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;yellow\u0026#34;, StringMatchMode.es())); query.and().with(owner, colors); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } "},{"uri":"https://strolch.li/development/","title":"Development","tags":[],"description":"","content":"Prerequisites To start developing Strolch you need an installed:\n Java JDK 17 Apache Maven 3.x  Building Strolch Note: You don\u0026rsquo;t have to build Strolch if you want to use the version on Maven central, but if you need a snapshot version, or the release you want isn\u0026rsquo;t on central, then go ahead and build Strolch.\n Building Strolch is just a few lines:\ngit clone https://github.com/strolch-li/strolch.git cd strolch mvn clean install -DskipTests  Note: To run the tests you will need to configure the PostgreSQL Databases. See the README in the module.\n After running the Maven build, you will have a full build of all Strolch projects. Now you can start modifying the projects, and add your own features, or, far more interesting, start developing your projects using the Strolch agent.\nCreating a Strolch App To create your own Strolch App, you can use Maven\u0026rsquo;s archetype generation. There are two versions, one is a simple Java App which you can use to directly access the Strolch runtime, and the second is to create a Java Web App, which is the usual way to run Strolch runtimes.\nNote: you need to have installed Strolch to your local maven repo, otherwise the archetype won\u0026rsquo;t be available.\n Creating a Java Strolch Web App The following shows the maven command to create the new maven project.

Please download the relevant platform\u0026rsquo;s package, unpack it, and add the bin directory to your path variable.\nOnce NodeJS is installed, then you can prepare the web dependencies:\ncd src/main/webapp/ npm install bower -g npm install gulp -g npm install bower install gulp cd ../../..  Note: Whenever the bower.json is changed then you should again call npm install inside the webapp folder.\n Building and running the WAR Building the WAR uses the package maven goal, but to have the optimized WAR use the release profile.\nTo run this WAR, we must configure the path of Strolch\u0026rsquo;s runtime in the StrolchBootstrap.xml file, by updating the following block, setting the absolute path to the runtime from the new project:\n\u0026lt;env id=\u0026#34;test\u0026#34; default=\u0026#34;true\u0026#34;\u0026gt; \u0026lt;root\u0026gt;/absolute/path/to/\u0026amp;lt;my-artifactId\u0026amp;gt;/runtime\u0026lt;/root\u0026gt; \u0026lt;environment\u0026gt;test\u0026lt;/environment\u0026gt; \u0026lt;/env\u0026gt; Now we can build the project using the configured environment:\nmvn clean package -Prelease -Dstrolch.env=test Now copy the WAR from the target/ directory to the webapps/ directory of your Tomcat 9.x installation.

The following are simple examples:  StartupPlcService\nimport li.strolch.persistence.api.StrolchTransaction; import li.strolch.plc.core.PlcHandler; import li.strolch.plc.core.PlcService; public class StartupPlcService extends PlcService { public static final String PLC = \u0026#34;PLC\u0026#34;; public static final String STARTED = \u0026#34;Started\u0026#34;; public static final String STOPPED = \u0026#34;Stopped\u0026#34;; public StartupPlcService(PlcHandler plcHandler) { super(plcHandler); } @Override public void start(StrolchTransaction tx) { send(PLC, STARTED); super.start(tx); } @Override public void stop() { send(PLC, STOPPED); super.stop(); } } ConveyorPlcService\nimport java.util.concurrent.ScheduledFuture; import java.util.concurrent.TimeUnit; import li.strolch.plc.core.PlcHandler; import li.strolch.plc.core.PlcService; import li.strolch.plc.model.PlcAddress; public class ConveyorPlcService extends PlcService { public static final int BOX_TRANSFER_DURATION = 30; private static final String R_CONVEYOR_01 = \u0026#34;Conveyor01\u0026#34;; private static final String A_START_BUTTON = \u0026#34;StartButton\u0026#34;; private static final String T_MOTOR_ON = \u0026#34;MotorOn\u0026#34;; private static final String T_MOTOR_OFF = \u0026#34;MotorOff\u0026#34;; private static final String A_BOX_DETECTED = \u0026#34;BoxDetected\u0026#34;; private boolean motorOn; private ScheduledFuture\u0026lt;?\u0026gt; motorStopTask; public ConveyorPlcService(PlcHandler plcHandler) { super(plcHandler); } @Override public void handleNotification(PlcAddress address, Object value) { String resource = address.resource; String action = address.action; if (!resource.equals(\u0026#34;Conveyor01\u0026#34;)) throw new IllegalStateException(\u0026#34;Unexpected resource \u0026#34; + resource); boolean active = (boolean) value; if (action.equals(A_START_BUTTON)) { if (active) { logger.info(\u0026#34;Start button pressed.

To have less configuration files and make it easier to reconfigure at runtime, this data is stored in normal Strolch Resources.\nIn this example we will use simple Raspberry Pi GPIOs. For convenience, and also when sharing I/O definitions with external partners, it is easier to use a CSV file to define the I/Os and then use the PlcAddressGenerator to generate and validate the model.\nFor this purpose in this example, we will use one conveyor with 2 inputs and 1 output. The CSV file should have the following content:\n  Description,Type,SubType,Device,Pin,Resource,Action1,Action2,Connection,DeviceId Material Flow,Group,,,,,,,,MaterialFlow Conveyor 1,Input,Pin,,4,Conveyor,Occupied,,raspiBcmGpioInput Conveyor 1,Input,Pin,,17,Conveyor,BoxDetected,,raspiBcmGpioInput Conveyor 1,Output,Pin,,18,Conveyor,MotorOn,MotorOff,raspiBcmGpioOutput The CSV headers are as follows:\n Description → a simple description for this PlcAddress Type →  Group → Must be the first line and generates a PlcLogicalDevice, all succeeding lines are grouped to this device. Add additional to group further devices Input → defines a boolean input Output → defines a boolean output Virtual → defines a virtual address which has no corresponding hardware connection. Used for internal communication. DataLogicScanner → defines an address to read barcodes from a DataLogic Scanner. The actions must be left empty as the keys Barcode (address), On and Off (telegrams) will be generated.   SubType → For Input and Output types →  DevPin, DevPin0 → Generates the address as \u0026lt;Connection\u0026gt;.\u0026lt;Device\u0026gt;.\u0026lt;Pin\u0026gt;. DevPin0 decrements the Device and Pin values by one. Pin → Generates the address as \u0026lt;Connection\u0026gt;.\u0026lt;Pin\u0026gt;.   For Virtual types →  Boolean String   Device → Device number Pin → The pin number on the device Resource → The resource ID with which to notify the agent Action1 → The action ID Action2 → The second action ID if required Connection → The ID of the PlcConnection with which this I/O is attached DeviceId → For type Group: Set the ID of this PlcLogicalDevice being generated  When you use this file as input for the PlcAddressGenerator, then it will generate PlcLogicalDevice, PlcAddress and PlcTelegram elements:\n\u0026lt;StrolchModel\u0026gt;

E.g. The action On would send true, and Off would send false. This is semantics, and is defined in each project depending on the hardware.\n Copy the file plc-state.xml to your runtime and reference it by use of a \u0026lt;IncludeFile file=\u0026quot;plc-state.xml\u0026quot; /\u0026gt; element.

A transaction is opened for a realm, and grants access to the model of the agent. Transactions are implemented as a Java try-with-resources by implementing the AutoCloseable interface. This makes it trivial to understand the scope of a transaction.\nTransactions handle the following:\n Opening and closing database connections Releasing locks to strolch elements, if tx.lock(StrolchRootElement) or tx.lock(Locator) was called Performing Commands by executing them in the added order, and validating them first. Exception handling Auditing Updating observers  When a transaction is opened, it is by default read-only, i.e. does not perform any commands when it is closed. Should the TX perform commands, then it is important to call tx.commitOnClose(), but only at the end of the work, so that exception handling can properly work if something goes wrong.\nStrolchTransaction offers a myriad of methods:\n find element by its Locator get methods for elements by type and id, or using a StringParameter or StringListParameter references methods to add, update or remove elements assert privilege access get a new element by its template check if an element exists by type and id get streams for elements add commands for execution  Transactions are opened by accessing the realm, but there are convenience methods depending on the use-case:\n In Services: by calling one of the openTx()-methods In Commands: Transactions are already open, use method tx() to get instance. REST API: RestfulStrolchComponent.openTx()  Note: don\u0026rsquo;t open a new TX inside a TX for the same realm!\n Important is to always open the transaction as a try-with-resource block and to define if the TX should commit, or not:\ntry (StrolchTransaction tx = openTx(...)) { // read lock our object  Locator ferrariLoc = Resource.locatorFor(\u0026#34;Car\u0026#34;, \u0026#34;ferrari\u0026#34;); tx.lock(ferrariLoc); // find a car by locator  Resource ferrari = tx.findElement(ferrariLoc); // get a car by ID  Resource opel = tx.getResourceBy(\u0026#34;Car\u0026#34;, \u0026#34;opel\u0026#34;, true); // modify ball  opel.setName(\u0026#34;Opel Corsa\u0026#34;); tx.update(opel); // get by string reference  StringParameter ownerP = ferrari.getParameter(\u0026#34;relations\u0026#34;, \u0026#34;owner\u0026#34;, true); Resource owner = tx.getResourceBy(ownerP, true); // get by string list reference  StringListParameter previousOwnersP = opel.getParameter(\u0026#34;relations\u0026#34;, \u0026#34;previousOwners\u0026#34;, true); List\u0026lt;Resource\u0026gt; previousOwners = tx.getResourcesBy(previousOwnersP, true); // check resource exists  if (tx.hasResource(\u0026#34;Car\u0026#34;, \u0026#34;audi\u0026#34;)) { Resource audi = tx.getResourceBy(\u0026#34;Car\u0026#34;, \u0026#34;audi\u0026#34;, true); // assert has privilege to remove a car  tx.assertHasPrivilege(Operation.REMOVE, audi); // remove the car  tx.remove(audi); } // iterate all cars  tx.streamResources(\u0026#34;Car\u0026#34;).forEach(car -\u0026gt; { logger.info(\u0026#34;Car: \u0026#34; + car.getId()); }); // commit if TX was changed  if (tx.needsCommit()) tx.commitOnClose(); } "},{"uri":"https://strolch.li/documentation/policies/","title":"Policies","tags":[],"description":"","content":"Policies Policies are an integral part when writing business logic in Strolch. In many cases it would suffice to write all such logic in Services and Commands, but as soon as behaviour can change, depending on the element being accessed, then this would quickly lead to many if/else blocks.\nSince writing large if/else blocks is not maintanable in the long run, Strolch offers a different approach. All Strolch elements can store Policy definitions. This is a simple key/value store where the key defines the type of policy, and the value references the policy to use.\nCurrently there are two ways to reference a policy in Strolch, either via a key which defines a further lookup in the PolicyHandler, or directly as the name of the class to instantiate.\nUsing policies in Strolch gives the additional possibility of easily changing the behaviour at runtime, as a Service and/or Command would delegate the behaviour to the currently configured policy on the releveant element.\nPolicies are implemented by defining an abstract class and extends StrolchPolicy. This abstract class then defines the API of the actual policy. A concrete class then extends this abstract class and implements the concrete methods.\nPolicies are registered on Resources, Orders, Activities and Actions. The following shows defining two policies on a Resource, a PlanningPolicy, an ExecutionPolicy in XML:\n\u0026lt;Resource Id=\u0026#34;myResource\u0026#34; Name=\u0026#34;My Resource\u0026#34; Type=\u0026#34;MyType\u0026#34;\u0026gt; ... \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;PlanningPolicy\u0026#34; Value=\u0026#34;key:SimplePlanning\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;java:li.strolch.policytest.TestSimulatedExecutionPolicy\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt;  Note how the PlanningPolicy has a value of key:SimplePlanning and the ExecutionPolicy defines a reference to an actual class.\n To use the PolicyHandler, it must be configured in the StrolchConfiguration.xml as follows:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;dev\u0026#34;\u0026gt; \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;PolicyHandler\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.policy.PolicyHandler\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.policy.DefaultPolicyHandler\u0026lt;/impl\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;readPolicyFile\u0026gt;true\u0026lt;/readPolicyFile\u0026gt; \u0026lt;policyConfigFile\u0026gt;StrolchPolicies.xml\u0026lt;/policyConfigFile\u0026gt; \u0026lt;/Properties\u0026gt; \u0026lt;/Component\u0026gt; \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; And this policy handler implementation requires a file where the lookups for the policies is defined, e.g.:\n\u0026lt;StrolchPolicies\u0026gt; \u0026lt;PolicyType Type=\u0026#34;PlanningPolicy\u0026#34; Api=\u0026#34;li.strolch.policytest.TestPlanningPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;SimplePlanning\u0026#34; Class=\u0026#34;li.strolch.policytest.TestSimplePlanningPolicy\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; \u0026lt;PolicyType Type=\u0026#34;ExecutionPolicy\u0026#34; Api=\u0026#34;li.strolch.execution.policy.ExecutionPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;SimulatedExecution\u0026#34; Class=\u0026#34;li.strolch.execution.policy.RandomDurationExecution\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; \u0026lt;PolicyType Type=\u0026#34;ConfirmationPolicy\u0026#34; Api=\u0026#34;li.strolch.policytest.TestConfirmationPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;NoConfirmation\u0026#34; Class=\u0026#34;li.strolch.policytest.TestNoConfirmationPolicy\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; \u0026lt;/StrolchPolicies\u0026gt; Now at runtime we can access the policies:\npublic class MyService extends AbstractService\u0026lt;ServiceArgument, ServiceResult\u0026gt; { @Override protected ServiceResult internalDoService(ServiceArgument arg) throws Exception { try (StrolchTransaction tx = openArgOrUserTx(arg)) { Resource res = tx.getResourceBy(\u0026#34;MyType\u0026#34;, \u0026#34;myTestResource\u0026#34;); PlanningPolicy planningPolicy = tx.getPolicy(res, PlanningPolicy.class); planningPolicy.plan(...); ExecutionPolicy executionPolicy = tx.getPolicy(res, ExecutionPolicy.class); executionPolicy.toExecution(...); tx.commitOnClose(); } return ServiceResult.success(); } } "},{"uri":"https://strolch.li/documentation/observers/","title":"Observers","tags":[],"description":"","content":"Observers All changes done in a Strolch transaction are recorded and then propagated to any registered observers.\nThe observer feature is opt-in and is configured for each realm.

In Strolch a report is defined by using its own model, i.e. a Report is a Resource of type Report.\nA report consists of the following parts:\n policy definition, thus allowing extensions basic configuration like base object type, order direction, etc. column definitions joins ordering definition filters  An example of a report is as follows:\n\u0026lt;Resource Id=\u0026#34;stockReport\u0026#34; Name=\u0026#34;Stock Report\u0026#34; Type=\u0026#34;Report\u0026#34;\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;parameters\u0026#34; Name=\u0026#34;parameters\u0026#34; Type=\u0026#34;Parameters\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;objectType\u0026#34; Index=\u0026#34;20\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Object Type\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;Player\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;descending\u0026#34; Name=\u0026#34;Descending order\u0026#34; Type=\u0026#34;Boolean\u0026#34; Value=\u0026#34;true\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;ordering\u0026#34; Name=\u0026#34;Ordering\u0026#34; Type=\u0026#34;Ordering\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;name\u0026#34; Name=\u0026#34;Name\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;noTeamFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:Equals\u0026#34; Value=\u0026#34;!\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Slot\u0026#34; Value=\u0026#34;Bags/relations/team\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;columns\u0026#34; Name=\u0026#34;Display Columns\u0026#34; Type=\u0026#34;Display\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;name\u0026#34; Name=\u0026#34;Player\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;birthDate\u0026#34; Name=\u0026#34;Birth date\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;Bags/parameters/birthDate\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;team\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;joins\u0026#34; Name=\u0026#34;Joins\u0026#34; Type=\u0026#34;Joins\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;Team\u0026#34; Index=\u0026#34;10\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;Player\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ReportPolicy\u0026#34; Value=\u0026#34;java:li.strolch.report.policy.GenericReport\u0026#34;/\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; This report\n shows all Resources of type player (parameter objectType) → marks the object type to be show in the filter criteria (default), and that its sorting index is at 20. orders the report by player\u0026rsquo;s name (parameter bag ordering) filters out all players with no team assigned (parameter bag noTeamFilter) defines three columns: Player, Birth date, Team (paramger bag columns) joins in the resource of type Team Uses the GenericReport class to generate the report  GenericReport The default generic report implemented in Strolch has the following features and options:\nParameters The parameters bag can contain the following parameters:\n  objectType → the base type of object to get the input for the report. This means that the Interpretation is set to one of:\n Resource-Ref Order-Ref Activity-Ref  and that the UOM and value of the parameter is set to the type of element with which to retrieve the elements from the strolch model.\n  descending → boolean flag to define if sorting is in descending order\n  allowMissingColumns → flag to define if no exception should be thrown if a column is missing\n  dateRangeSel → defines a lookup parameter to use as a date range selector. This requires input when executing the report\n  Note: that the attributes Hidden and Index define the visibility and sorting index as filter criteria respectively.\n Lookups Many of the features of the generic report rely on looking up a value on the referenced element. The following shows the ways that a lookup can be performed:\n $id → lookup the ID of the element $name → lookup the name of the element $type → lookup the type of the element $date → lookup the date of the element (only possible on Order and Activity elements) $state → lookup the state of the element (only possible on Order and Activity elements) Bags/\u0026lt;bag_id\u0026gt;/\u0026lt;param_id\u0026gt; → a lookup on the selected element by bag ID and parameter ID $search:\u0026lt;parent_ref_id\u0026gt;:Bags/\u0026lt;bag_id\u0026gt;/\u0026lt;param_id\u0026gt; → searches for a parameter with the given bag and parameter, and if it does not exist, looks for the parent with the given parent_ref_id on the element. This allows a recursive search up a tree of elements which all have the same parameter referencing a parent. relations bag  Note: these definitions are set as the value of a Parameter, and the Interpretation and UOM of the parameter is used to find the element on which to perform the lookup. I.e. the following definition:\n \u0026lt;Parameter Id=\u0026#34;name\u0026#34; Name=\u0026#34;Player\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; defines that we want to lookup the name of the resource of type Player.\nOrdering Ordering, i.e sorting is done by adding the parameter bag with the id ordering and each parameter defines a column to order by. The sequence of the ordering is defined by the index value assigned to each parameter.\nFiltering Filtering use additional Strolch Policies which implement the operator function. I.e. performing an equals, etc. The following ReportFilterPolicy are available and should be added in your StrolchPolicies.xml file:\n\u0026lt;StrolchPolicies\u0026gt; ... \u0026lt;PolicyType Type=\u0026#34;ReportFilterPolicy\u0026#34; Api=\u0026#34;li.strolch.report.policy.ReportFilterPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;GreaterThan\u0026#34; Class=\u0026#34;li.strolch.report.policy.GreaterThanReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;LessThan\u0026#34; Class=\u0026#34;li.strolch.report.policy.LessThanReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;Equals\u0026#34; Class=\u0026#34;li.strolch.report.policy.EqualsReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;Contains\u0026#34; Class=\u0026#34;li.strolch.report.policy.ContainsReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;IsIn\u0026#34; Class=\u0026#34;li.strolch.report.policy.IsInReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;ValueRef\u0026#34; Class=\u0026#34;li.strolch.report.policy.ValueRefReportFilter\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; ... \u0026lt;/StrolchPolicies\u0026gt; From this we can see that we can perform a GreaterThan, LessThan and Equals filtering. These filters can also be negated by prefixing the filter value with an exclamation mark (!).\nA special case for the filter values are filters on dates. If you are filtering on a date, then you can use the special operator now(). This filter will use the current date and time and will add/subtract the ISO8601 period passed as an argument to the operator.\nThe following shows examples of these filters:\n\u0026lt;ParameterBag Id=\u0026#34;minQtyFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:GreaterThan\u0026#34; Value=\u0026#34;10\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Product\u0026#34; Value=\u0026#34;Bags/parameters/quantity\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;notEmptyFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:Equals\u0026#34; Value=\u0026#34;!\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;Bags/relations/team\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;threeMonthsAgoFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:LessThan\u0026#34; Value=\u0026#34;now(-P3M)\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;FromStock\u0026#34; Value=\u0026#34;$date\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt;  Note: One parameter defines which policy gets used and the key:\u0026lt;name\u0026gt; value references a policy defined in the StrolchPolicies.xml file. Further the lookup is defined in the fieldRef parameter.\n Joins To add columns from data which is not on the element denoted by the base object type, we can join further elements. This is done by adding the parameter bag joins and then each parameter references an element to join. The joining is done as follows:\n The Intepretation and UOM define which object we want to join, i.e. resource of type foo The value of the parameter defines the type of element on which to find the reference The join ordering is not relevant, as the tree is traversed accordingly At least one join must reference the base object type The lookup of the join is done by finding a parameter with any ID, which has the same Interpretation and UOM as the join definition The attributes Hidden and Index define the visibility and sorting index as filter criteria respectively.  Thus the following:\n\u0026lt;ParameterBag Id=\u0026#34;joins\u0026#34; Name=\u0026#34;Joins\u0026#34; Type=\u0026#34;Joins\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;Team\u0026#34; Index=\u0026#34;10\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;Player\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;Country\u0026#34; Index=\u0026#34;5\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Country\u0026#34; Value=\u0026#34;Team\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; Performs two joins: First we join a resource of type Team by finding the relevant parameter on the Player resource, and then we lookup a resource of type Country on the previously joined Team resource.\nExecution of Reports To execute a reports, we must instantiate the Report and can then directly generate a JsonObject stream, which we can then pipe to a browser, file, etc.:\nStream\u0026lt;JsonObject\u0026gt; jsonObjectStream = new Report(tx, reportId).doReportAsJson(); If you prefer a CSV report:\ntry (CSVPrinter csvP = new CSVPrinter(new OutputStreamWriter(out), CSVFormat.DEFAULT.withHeader(headers).withDelimiter(\u0026#39;;\u0026#39;))) { // do report without AsJson, and then iterating each row and sending to a CSV writer  report.doReport().forEach(row -\u0026gt; { try { csvP.printRecord(row.valueStream().collect(Collectors.toList())); // add to CSV  } catch (Exception e) { logger.error(\u0026#34;Could not write CSV row\u0026#34;, e); } }); } Filter Criteria Predefining filters is a good start, but in some case you only want a portion of the actual filtered data. For instance if you make a stock report, you might only want one location. This information is dynamic and thus not stored on the report definition.\nTo perform these dynamic filterings, one would call the filter()-method on the report, passing the type of element to be filtered, and to which element IDs to reduce the report data to. The following reduces the report to only return the rows with the product01 Product and location02 Location elements:\nnew Report(tx, \u0026#34;stockReport\u0026#34;) .filter(\u0026#34;Product\u0026#34;, \u0026#34;product01\u0026#34;) .filter(\u0026#34;Location\u0026#34;, \u0026#34;location02\u0026#34;) .doReportAsJson() It is possible to find the possible filter criteria dynamically using the generateFilterCriteria() method.\nDate Range Filtering The last option to filter dynamically is using a date range selector. Define the dateRangeSel lookup parameter, and then set the date range on the instantiated report:\nModel the report in XML:\n\u0026lt;ParameterBag Id=\u0026#34;parameters\u0026#34; Name=\u0026#34;parameters\u0026#34; Type=\u0026#34;Parameters\u0026#34;\u0026gt; ... \u0026lt;Parameter Id=\u0026#34;dateRangeSel\u0026#34; Name=\u0026#34;Date Range Selector\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Product\u0026#34; Value=\u0026#34;Bags/parameters/expirationDate\u0026#34;/\u0026gt; ... \u0026lt;/ParameterBag\u0026gt; And now call the report in Java:\nDate from = new Date(LocalDate.of(2016, 1, 1).toEpochDay() * 86400000); Date to = new Date(LocalDate.of(2017, 1, 1).toEpochDay() * 86400000); DateRange dateRange = new DateRange().from(from, true).to(to, false); List\u0026lt;JsonObject\u0026gt; result = new Report(tx, \u0026#34;stockReport\u0026#34;) //  .filter(\u0026#34;Product\u0026#34;, \u0026#34;product01\u0026#34;) //  .dateRange(dateRange) //  .doReportAsJson()  Note: See the GenericReportTest for examples.\n "},{"uri":"https://strolch.li/documentation/priviles/","title":"Privileges","tags":[],"description":"","content":"Privileges No framework is complete without user management and privilege validation.

The privileges can overlap, a validation is performed to make sure that the one role doesn\u0026rsquo;t deny and another role allows a specific action.\nAs explained in the Privilege Configuration section, users are defined in the PrivilegeUsers.xml file, and roles are defined in the PrivilegeRoles.xml file.\nLet\u0026rsquo;s assume the following user and role definition:\n\u0026lt;Users\u0026gt; \u0026lt;User userId=\u0026#34;1\u0026#34; username=\u0026#34;jill\u0026#34; password=\u0026#34;$PBKDF2WithHmacSHA512,10000,256$61646d696e$cb69962946617da006a2f95776d78b49e5ec7941d2bdb2d25cdb05f957f64344\u0026#34;\u0026gt; \u0026lt;Firstname\u0026gt;Jill\u0026lt;/Firstname\u0026gt; \u0026lt;Lastname\u0026gt;Someone\u0026lt;/Lastname\u0026gt; \u0026lt;State\u0026gt;ENABLED\u0026lt;/State\u0026gt; \u0026lt;Locale\u0026gt;en-GB\u0026lt;/Locale\u0026gt; \u0026lt;Roles\u0026gt; \u0026lt;Role\u0026gt;AppUser\u0026lt;/Role\u0026gt; \u0026lt;/Roles\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;Property name=\u0026#34;realm\u0026#34; value=\u0026#34;execution\u0026#34; /\u0026gt; \u0026lt;/Properties\u0026gt; \u0026lt;/User\u0026gt; \u0026lt;/Users\u0026gt; \u0026lt;Roles\u0026gt; \u0026lt;Role name=\u0026#34;AppUser\u0026#34;\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;AllAllowed\u0026gt;true\u0026lt;/AllAllowed\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.model.query.StrolchQuery\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;AllAllowed\u0026gt;true\u0026lt;/AllAllowed\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.search.StrolchSearch\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;AllAllowed\u0026gt;true\u0026lt;/AllAllowed\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;/Role\u0026gt; \u0026lt;/Roles\u0026gt; This configuration contains one user and one role. The user jill has the role AppUser and the role AppUser has three privileges assigned.\nNote how the user\u0026rsquo;s password is configured similar to a unix password definition: Using the dollar sign \u0026amp; first the hashing algorithm is configured ( algorithm, iterations, key length), then the salt, followed by the password hash.\nNote: The password can also still be saved using two separate fields: a salt and password field. This configuration will be immediately changed to the unix form, so won\u0026rsquo;t be described further here.\n Further a user always has a firstname and last name. Optionally a locale can be set, otherwise the system locale is used. The user\u0026rsquo;s state must be defined as one of NEW, ENABLED, DISABLED, EXPIRED or SYSTEM. A user can only authenticate/login with the state ENABLED. A user can have any number of properties, which can then be used at runtime. A user can also reference any number of roles, the assigned privilege can overlap, a global configuration mode defines how duplicate privileges are handled.\nRoles have a name and any number of Privilege definitions. A Privilege has a name, which in many cases is the name of Java class/interface on which an action is being invoked. The policy value defines which policy to use when evaluating the privilege access. The privilege definition is defined in the PrivilegeConfig.xml and is the name of a class to call for privilege validation.\nFurther the privilege definitions can have a AllAllowed boolean flag, or any number of Allow or Deny values. How these values are interpreted is defined in the policy implementation. A policy takes three input parameters:\n PrivilegeContext → supplied by privilege and gives access to the Certificate, thus identifying the user for which privilege access is to be validated. IPrivilege → Contains the privilege values: AllAllowed, Allow and Deny Restrictable → An interface from which the privilege name is retrieved, and the associated value. The value is an object, and is cast to the relevant input in the concrete privilege policy.  The following privilege policies are already implemented:\n DefaultPrivilege → simple policy where the passed Restrictable is expected to return a String value, which is compared with allow and deny values. Internal: RoleAccessPrivilege → policy used for the internal privileges PrivilegeGetRole, PrivilegeAddRole, PrivilegeModifyRole or PrivilegeModifyRole Internal: UserAccessPrivilege → policy used for the internal privileges PrivilegeGetUser, PrivilegeAddUser, PrivilegeRemoveUser, PrivilegeModifyUser, PrivilegeAddRoleToUser, PrivilegeRemoveRoleFromUser, PrivilegeSetUserState, PrivilegeSetUserLocale or PrivilegeSetUserPassword Internal: UserAccessWithSameOrganisationPrivilege → Same as the UserAccessPrivilege but expects the authenticated user to have a property organisation and validates that the user being modified is in the same organisation. Internal: UsernameFromCertificatePrivilege → This policy expects a Restrictable to return the certificate of another authenticated user and is used when modifying an authenticated user, i.e. killing a session, or modifying its current state, e.g. locale etc. Internal: UsernameFromCertificateWithSameOrganisationPrivilege → Same as UsernameFromCertificatePrivilege but expects the authenticated user to have a property organisation and validates that the user being modified is in the same organisation.  Note: As a rule, the sequence is AllAllowed → Allow → Deny → default deny\n "},{"uri":"https://strolch.li/history/","title":"History","tags":[],"description":"","content":"Overview Strolch is an open source component based software agent written in Java and can be compared, in a light sense, with the Java EE stack: Strolch takes care of persistence, implements Services for use cases, Commands as re-usable algorithms and has a parameterized data model.\nStrolch has an intrinsic understanding for mandates, which are called realms so that a single agent can be used to implement applications with multiple users/customers for instance in SaaS environments.\nThe parameterized data model consists of three top level objects, Resources, Orders and Activities. These objects can have any number of ParameterBags which in turn can have any number of Parameters on them. This allows for a very dynamic modelling of data structures including modification at run time. Multiple ready to use Parameter types are already implemented which handle the primitive types in Java including ListParameters for collections of these primitive types.\nOne of the main features of the Strolch agent, is that persistence is handled transparently and the user must not be worried about databases and the likes. Currently there are two implementations for persisting the Strolch model, a PostgreSQL and an XML file persistence. Currently both persistence layers persist the data by converting to XML and storing it into the database. The XML file persistence stores each object in its own file.\nThe agent itself has a small memory footprint and requires very few components to start. For the agent to be useful it needs additional functionality which is implemented in StrolchComponents. Each component is registered via its Java interface on the agent and is bound to the life cycle of the agent. When the agent is started, these components can be retrieved and used to perform any number of functionalities. This is the preferred way to extend the Strolch agent. There are a number of components already implemented, e.g. the ServiceHandler which executes Services in a controlled fashion and can validate authorized access to these services.\nNo software product is complete without a system for authentication and authorization. Strolch implements this by using the Privilege framework which has been written by Robert von Burg. The standard ServiceHandler detects the existence of the PrivilegeHandler and then validates that the user has authorization to perform the service. This framework is implemented as its own Strolch component, thus can be retrieved at any time during execution to perform fine grained and special authorization validation.\nMotivation A question often asked is why create Strolch. What are its benefits in contrast to using Java SE with an OR-Mapper like Hibernate, or using Java EE on JBoss or Glassfish? Especially since many of the features existing in those stacks needed to be re-created in Strolch.\nThe first answer to this question is that those systems are often overly complicated and bloated. Java SE with Hibernate certainly is a viable option when it comes to being light-weightier but Hibernate, even though it is supposed to, often fails to truly help remove the need to really understand an RDBMS. Often enough Hibernate will just get in the way of the most important part of development: writing the business code. Being an OR-Mapper which is supposed to implement all the nitty-gritty details of an RDBMS system, Hibernate, and JPA for that matter, still often has the developer go back to understanding these details.\nStrolch tries a different approach to persistence. Instead of writing pojos/entities, Strolch\u0026rsquo;s model has the concept that each element\u0026rsquo;s attributes are part of a composition pattern: each attribute is its own object and thus can be dynamically changed at runtime, but also makes persistence of such an element generic. Instead of having fixed attributes for a concrete class, these parameters are stored in a map and are accessed through the parameter\u0026rsquo;s ID.\nAssigning an ID to an attribute for accessing of course brings its own downsides, i.e. the parameter might simply not be there, when being accessed. This is certainly an issue that the developer must handle, when implementing a project using Strolch, but allows the developer to not need to worry about persistence, as this is generically handled.\nSince the persistence is generically handled, and Strolch stays lightweight on its requirements at runtime, the developer can quickly get down to what is important for business value: Writing the business logic and the presentation layer. Here too Strolch tries to help the developer by bringing in concepts which are easy to follow: Use cases are implemented as Services, and re-usable business logic is put into Commands.\nThere will be reasons against using Strolch, as there will be against using the Java EE stack, or an OR-Mapper or even the Java ecosystem for that fact. Important is to note, that the concepts behind Strolch are nothing new, but have been implemented in at least two previous proprietary products. Since those products are not accessible to the public, it was decided that a re-implementation might be of use to the programming community at large.\nCurrently, there is at least one company using Strolch in a commercial project which helps drive Strolch\u0026rsquo;s development and further motivates its existence.\nStrolch is an open source project and licensed under the Apache License 2.0.\n##Technology Strolch is written in Java and is programmed against the JDK 8. Strolch runs on any JRE 8 compliant environment. Strolch is tested on the Oracle JRE 8.\n"},{"uri":"https://strolch.li/blog/","title":"Blog","tags":[],"description":"","content":"About The official Strolch blog with news, ideas, and thoughts on using Strolch.\nStrolch is an open source component based software agent written in Java and can be compared, in a light sense, with the Java EE stack: Strolch takes care of persistence, implements Services for use cases, Commands as re-usable algorithms and has a parameterized data model.\nEntries  Strolch PLC now also on Maven Central  Strolch PLC version 1.0.7 has been deployed to Maven Central for easier integration into your projects\n Release of Strolch 1.6.100  The 100. release of the 1.6 branch and a brand new website!\n Strolch Reports  Strolch can do reports!\n Strolch Searches  Strolch queries are deprecated!\n Wow, the many changes!

The fields are mapped as Parameter objects, of which the important primitives are available.\nThe nice part about this framework is, that you can be up and ready in a matter of minutes, and start building your project immediately in that you open your favourite XML editor and start modelling your data.\nOnce your data is defined, you write your business logic in the form of Services, Commands and Searches. There are many predefined services and commands to manipulate the object model, so that you write your own services when you need to enforce special business rules.\nThrough the use of Policy objects, you decouple algorithms from your object model, so that at runtime you can change the behaviour, or easily implement different behaviour depending on your use-case. For instance you might have a simple billing service which performs a few preparatory steps, and then calls the configured billing policy to execute the billing depending on the customer, the warehouse, etc.\nAnd of course persistence is as simple as configuring the persistence handler, pointing to your RDBMS and then setting the mode to CACHED. For you as a developer there is no more thinking in terms of SQL etc., as this is completely hidden from the developer. There is even a simple file persistence layer if you are running IoT devices.\nThe runtime can be just about anything. Usually it is run inside an Apache Tomcat instance as a webapp, as a WEB UI has been required for all current Strolch projects. You could just as well use a main class. Accessing the Strolch Agent remotely is usually done through REST.\nStrolch is being actively developed, and customers constantly give us reasons to improve and extend the framework. There is a Polymer Inspector component which makes it easy to see and manipulate the actual data. The new Search API makes it really easy to query your data.\nYes, Strolch is different, but the concept has come out of the planning and execution segment, and has been refined over the years until it has become what it is today.\nAPI Check out the API page to see how to use Strolch.\nMore to motivation etc.\n"},{"uri":"https://strolch.li/categories/","title":"Categories","tags":[],"description":"","content":""},{"uri":"https://strolch.li/tags/","title":"Tags","tags":[],"description":"","content":""}]

Better performance for reports on large joins. Move to JDK 11+. Refactoring to use of Java 9 LocalDateTime and ZonedDateTime where applicable. Added Controllers for better execution handling. Significantly simplified the methods to change the model. Simpler methods to retrieve relationship entities. Updated most libraries to their latest versions. Added a DataArchiveHandler to archive entities. Added require password change feature, and storing of login and password change history LDAP integration Added session keep alive Search expression simplifications New TextParameter for when persisting large values with whitespace and special characters Basic Auth for REST APIs, if no UI needed for scripting Many additional fixes, tweaks and helper functions  Another new addition to the Strolch family is Strolch PLC. The Strolch PLC code allows one to use the same model but on a device acting as a soft PLC, e.g. a Raspberry Pi. This PLC code can then communicate using WebSockets with a Strolch instance, having quite seamless interaction with Activities which really shows the potential of using Strolch\u0026rsquo;s model in the shop floor.\nWe\u0026rsquo;ve been running the Strolch PLC in a mission critical shop floor application to control conveyors which are filled by a dispensing robot.\nSo, Strolch 1.6.100 is out the door, go ahead and try it out.\n"},{"uri":"https://strolch.li/blog/post-00014/","title":"Strolch Reports","tags":[],"description":"Strolch can do reports!","content":"Strolch Reports Strolch can do reports!\n A feature we haven\u0026rsquo;t written about yet is the report API.

January 2017 and there are 53 new commits ahead of the tag.\nEnough of all the commits, lets get to the new features:\n Added new generic report creator Added Activity.TimeOrdering and updated Model XSD Implemented State Model on Activity/Actions Implemented execution of Activities Implemented EventBasedExecutionHandler Added StrolchXmlParser to quickly parse from a file Add Activity.remove(String) to remove an element Refactored LockHandler to use Locator Added Activity.getActionsWithState(State) Moved *ToFlat and *FromFlat Json Visitors to strolch model Added StrolchElementQuery.internal() Added Parameter.clearValue() and list parameters use , as sep Json Tags are now in Tags.Json and are drinking camel-case Moved PrivilegeAddUserService to command, added tests Lots of JavaDoc updates Refactored code for REST Inspector to use gson Added inspector REST api for activities Inspector now has offset/limit for queries Added new StringMapArgument for StrolchServices Added missing activity observer calls in AbstractTransaction Added StringMapResult to use as a ServiceResult Removed many visitors and implemented proper visitor pattern\u0026hellip; Don\u0026rsquo;t log stack trace if certificate does not exist SmtpMailer now understands whitelists for override Fixed locator finding for Activity and Action Fixed undo logic for general commands  To summarize, execution and reporting are the two new features that make Strolch really awesome! We use execution to perform a number of actions on a remote device connected to a Strolch agent through WebSockets. This allows serial and parallel execution of actions and of course locking of concurrently used resources.\nIn an enterprise world reports can never be missed, so we needed an API to create reports. Of course that API was created in a way that all things are done in Strolch: generically. Thus a report is created as a Resource, defining the report object, columns and any relevant joins.\nAnd one of the really cool things is that we have started with a UI for Strolch. There is now an Inspector with which the entire data model of a running agent can be seen. This inspector is built using Polymer and WebComponents and thus can be easily embedded in your application.\nTo facilitate the authentication of a user for the inspector, an authentication component was created as well. And of course i18n can\u0026rsquo;t be forgotten, so there is a component for that too.\nTo simplify tasks in a web project, there is also a StrolchJs repository where certain Strolch specific things are handled e.g. querying the authenticated user\u0026rsquo;s roles etc.\nThe release of the next Strolch version isn\u0026rsquo;t defined yet, as we are internally building a project on all these changes and with the release 1.0.0 of that project (which will be soon), we shall perform the next release of Strolch.\nUntil then, happy coding!\n"},{"uri":"https://strolch.li/blog/post-00011/","title":"Strolch now on Maven Central","tags":[],"description":"Release Version 1.3.0 released and deployed to Maven Central","content":"Strolch now on Maven Central Release Version 1.3.0 released and deployed to Maven Central\n We have released a new version of Strolch so that you can now go and use the the latest features in Strolch.\nFurther we have now deployed Strolch to Maven Central, so it is easier than ever to use Strolch in your projects.

Implemented REST API to query Orders, Resources and Activities/Actions Implemented REST API to update Resources and Orders from XML REST API to authenticate now adds a cookie, so authorization is much simpler. Added convenience methods in Service and Command to easily perform system user actions. Added audits for login/logout of users. Added audits for changes to privilege management.

The planning engine would work in combination of Order objects representing customer orders, Resource objects representing machines, human resources, etc., and Activity/Action hierarchies defining a workflow.\nWith the latest couple of commits to Strolch we have now added Activities and a basic planning of Actions onto Resources. Activities have an ordered list of IActivityElement which allows creating an arbitrary deep tree structure of Activity and Action elements.\nAction objects have a list of IValueChange objects which define the start, end and further value changes over time on a referenced Resource. Thus planning an Activity is done by iterating the Activity hierarchy and for every Action selecting a relevant Resource and then then applying the changes of the Action on to the referenced TimeState on the Resource.\nThis implementation is currently very simple as it ignores all constraints which a Resource might have. In further development we shall implement a Violation model so that UIs can be built to visualize the over-use of Resources.\nIn even further steps we would then start implementing algorithms to not just apply the changes onto a Resource, but to actually search the Resource for time slots when the value changes would not violate any constraints applied to the resource.\nWe are very much looking forward to these new features.

This first documentation explains the Strolch runtime and some of the do and don\u0026rsquo;t in Strolch code.\nBear with us, writing documentation takes time and can be outdated quickly, so we will make an effort to keep everything up to date and add more documentation, but this is a start.\nSo go ahead and read the documentation , and if you haven\u0026rsquo;t already, also read the rest of the website which should give some more insight into the what, why and how of Strolch.\n"},{"uri":"https://strolch.li/blog/post-00005/","title":"Strolch Release 1.0.0","tags":[],"description":"Finally Version 1.0.0 of Strolch has been released and can be downloaded immediately.","content":"Strolch Release 1.0.0 Finally Version 1.0.0 of Strolch has been released and can be downloaded immediately.\n Before 1.0.0 could be released, some major changes were decided, all driven by the first big project using Strolch as its underlying stack. Those changes were minor, and really major, but should make Strolch better and was important for the first release.\nHere is a list of the most interesting changes:\n Java 8 - Strolch was ported to Java 8. This gives a lot of cool features: The stream API, lambdas, the new time API, etc. TX refactoring: Strolch transactions are instances of Closeable so that they are closed using a try-with-resource block in Java7. The change that was required was to not auto commit. Now a TX is read-only and one has to set the auto commit as the last statement. See this commit for more information. Added a tx.flush() to allow an implementation to flush part of a transaction, this feature is vital to perform parts of a transaction before deciding if the TX should be committed. Fixed the issue where data store mode CACHED performed TRANSACTIONAL queries, instead of staying in-memory. ParameterSelection.stringListSelection() uses a StringMatchMode instead of just equals() ParameterSelection.dateRangeSelection() uses a DateRange instead of just equals() Added the MigrationsHandler to use to perform code migrations of production data bases where data shouldn\u0026rsquo;t go lost. And many more\u0026hellip;  Strolch 1.1.0 is already in development and can also be downloaded from the download page. Here you can see the current change list on GitHub. For instance heavy work has been done to implement privilege management by adding a REST API.

This parameter currently stores the value as a long in memory and serializes to ISO8601.

The implementation understands the concepts of migration, and validating the database schema, but currently a mechanism to automatically initialize the database with a minimal set of data was missing.\nMigrating a database for Strolch is mostly a one time thing. The object model in Strolch is quite static, so there is seldom a need to migrate the database. Domain specific changes, i.e. new Resources, or adding Parameters to Resources, is not a schema change. Thus, instead of going the way other frameworks go, e.g. Ruby on Rails, we built the data initialization right into the PersistenceHandler.\nNow if the PostgreSQL PersistenceHandler creates the schema, then it might also initialize the minimal set of data. For this to work, the PersistenceHandler checks if the flags allowSchemaCreation, allowSchemaDrop and allowDbInitOnSchemaCreate. If those flags are enabled, and the schema was created during initialization, then the database is also initialized with the contents of the XML file configured under key dataStoreFile of the relevant Realm.\nThe database initialization is done as a system user action which must have the name db_initializer. This is another fail-safe, so that on a production system, this user can simply be deleted.\nSo, Strolch 1.0.0-RC3 is out the door, go ahead and try it out.\n"},{"uri":"https://strolch.li/blog/post-00002/","title":"Release 1.0.0-RC2","tags":[],"description":"Scratch that RC1, here is the brand new 1.0.0-RC2 which can be downloaded on the download page.","content":"Release 1.0.0-RC2 Scratch that RC1, here is the brand new 1.0.0-RC2 which can be downloaded on the download page.\n So, as expected there were a few bugs, for instance the Strolch tutorial apps didn\u0026rsquo;t start, so now i fixed those and released an RC2.

To this affect we have now released version 1.0.0-RC1 which can be downloaded on the download page.\n Story Strolch as a component based software agent has been two years in the making. The concepts in Strolch have been taken from a proprietary planning, scheduling and controlling software agent, which was, and is been, used in industrial automation, logistics and production. Strolch was created to bring the concepts, which were working well for small teams to go-live with large projects in short to medium time-frames to the open source world.\nStrolch was completely rewritten using the key concepts of a parameterized object model and a component based agent but remembering which clutches the original implementation had, thus trying to eradicate those without bringing in new ones. It might not be perfect in version 1.0.0, but it is a starting point form which to carry on from.\nFeatures Strolch isn\u0026rsquo;t feature complete by a long shot, but it sure has got many features which make it useable in a concrete project, thus making sure it is not vaporware =)\nThe following is a list of key features, many of which were driven by concrete project requirements:\n Separate containers for models (mandates) Parameterized model with full CRUD for Resource and Order objects Timed values on Resources to map values by time Built-in versioning of model - configurable by Realm Transparent runtime modes: TRANSIENT, CACHED, TRANSACTIONAL* Service and Command pattern for reusing functionality XML File based persistence layer* PostgreSQL persistence layer* Querying using a fluent API Services to import and export a model to XML Integrated authentication and authorization to validate user privileges using Privilege Ready to use Observer pattern (currently) Read-only REST API to access the agent model remotely Configurable environments Opt-in audit trail (including read access, and the audits themselves) Basic components required to communicate with external devices using TCP/IP With the light weight implementation, where there are basically no third party libraries required for the normal runtime, Strolch has a minimal foot print which allows it to run on small devices for instance a BeagleBone Black. Using the in-memory mode, it is an easy feat to set up test environments with little to no further requirements than the JVM.  Future So what is planned for the future? Although Strolch has quite a few interesting features, it is by no way feature complete. The greatest wish is for Strolch to become a community driven platform, so many new features will arise in the future, but at least one major future feature which will be tackled in the near future and will certainly drive the next major release is a planning and scheduling engine using a Gantt chart to visualize the schedule.\nThe planning engine will use the timed values on Resources extensively to create a planning engine on which Workflows can be placed and allowing to detect violations and bottlenecks.\nAn extension of the planning of the scheduling engine will allow more than just placing Workflows on Resources, but actually searching groups of Resources for a time slot of when to place tasks. This will allow to use capacity constraints to plan and schedule workflows using different algorithms, and respecting calendars etc.\nFurther time will be spent on giving Strolch it\u0026rsquo;s own UI. Currently the idea is to use Google\u0026rsquo;s Polymer to implement the UI, thus creating reusable widgets that can be used in projects.\nTake it for a spin So, now the important part is for new users to start using Strolch for their own projects. Go ahead, check out the Downloads page for the latest release and then checkout the two tutorial applications to get yourself up to speed!\nDon\u0026rsquo;t hesitate to send us feedback or questions, we will be delighted to help you get your Strolch-based application up and running, or provide feedback to your concerns!\nDevelopers Robert von Burg Reto Breitenmoser Dr. Martin Smock\n*Currently Transactional mode is missing concrete implementation for querying for the XML persistence\n"},{"uri":"https://strolch.li/api/","title":"API","tags":[],"description":"","content":"Overview The Strolch API revolves around the StrolchTransaction object. The main concept is to implement your use cases in Service implementations. You open a transaction using the openTx(String)-method and then perform the use case by adding your Command instances to the transaction.\nTransactions are opened on a StrolchRealm. The realms are used to separate mandates in a single runtime instance of Strolch. Each realm has its own ResourceMap, OrderMap, ActivityMap instances from which the TX retrieves the elements.\nModel The Strolch model is implemented in the project li.strolch.model.\nThe Strolch model consists of three root level elements: Resource, Order and Activity. Each element has at least the following attributes:\n Id → the element\u0026rsquo;s id Name → the element\u0026rsquo;s name Type → the element\u0026rsquo;s type  Each root element can have any number of ParameterBag instances on it, which in turn can have any number of Parameters on it. Accessing these objects is always done by their IDs. Strolch root elements are always stored in the respective ElementMaps in their Strolch realm. Thus accessing a certain parameter from a Resource would look like this:\npublic class Test { public static void main(String[] args) { try (StrolchTransaction tx = openTx(realmName)) { Resource resource = tx.getResourceBy(\u0026#34;MyType\u0026#34;, \u0026#34;myResource\u0026#34;);

When configuring a Strolch runtime, realms are configured and for each realm the data store mode is set. Each realm has its own persistence configuration and can thus run in one of the 4 modes that the Strolch agent implements:\n EMPTY This is a transient data store mode, where no model changes are persisted, but they are only kept in memory. When the Strolch agent is started, this realm stays empty as no data is loaded. TRANSIENT This is the same as EMPTY, but with the difference that when the Strolch agent is started, an XML file is parsed and the in memory realm is populated with the elements parsed from that XML file. CACHED In this mode, all data is stored in memory, and any changes made are written back to the persistence layer. This allows for fast in-memory quries, but makes sure no data is lost when the agent is restarted.  Strolch Realms are also responsible for opening Transactions, as these are bound to the persistence layer configured for this realm. At runtime, a realm is then accessed from the ComponentContainer:\npublic class Example { public static void main(String[] args) { ComponentContainer container = getAgent().getContainer(); StrolchRealm realm = container.getRealm(StrolchConstants.DEFAULT_REALM); try (StrolchTransaction tx = realm.openTx()) { Resource resource = tx.getResourceBy(\u0026#34;TestType\u0026#34;, \u0026#34;MyTestResource\u0026#34;); } } } "},{"uri":"https://strolch.li/documentation/architecture/","title":"Architecture","tags":[],"description":"","content":"Architecture Birds View A Strolch agent\u0026rsquo;s architecture can be seen as a simple three-tier architecture. The presentation layer is mostly a web frontend, where the communication with the agent is done via REST API calls.\nThe agent itself implements the business logic using Services, Commands, Queries etc.\nThe agent can communicate with other 3rd systems using any API, where it is preferred to use JSON over REST.\nThe agent can use a standard RDBMS as a storage system, where currently DAOs have been implemented only for PostgreSQL. Should it be required, then any JDBC cabable RDBMS can be used, as no PostgreSQL specific SQL commands are used.\nThe following diagram helps visualize this:\nSquirrel View The following diagram shows a more detailed view of the architecture of a Strolch Agent:\nA Strolch agent consists of the following main parts:\n REST Endpoints → expose an API to access the Strolch agent outside of the Java VM Services and Commands → implements business logic Searches → implements specific queries against the Strolch model Components → Implements additional logic, which is best implement as a component. E.g. active components which have threads, etc. Realms → implements multi-tenant capabilities  In addition to the main parts, Strolch contains inherit capabilities, which gives Strolch unique features when compared to other Java Frameworks:\n Policies → Policies allow injecting different algorithms. All root elements can store Policy definitions, so that a service can delegate to a Policy and thus behave differently, depending on the element being accessed. Transactions → Transactions handle locking/unlocking of objects, updating the model and are the central API for the developer. Privileges → Strolch is user agnostic and any action, i.e. Service, Query, etc. is authorized against the authenticated user. Observers → modifications to the model are propagated to listeners using the observer pattern. Audits → Every access (read, modify) of the model are audited Versioning → modifications to objects are versioned and thus can be rolled back at a later time.

\u0026lt;/profiles\u0026gt; \u0026lt;/project\u0026gt; Now we need the rest of the directory structure:\n../strolch-bookshop/ - src/main/java/ - li/strolch/bookshop/ - \u0026lt;!-- java classes --\u0026gt; - src/main/resources/ - ENV.properties - appVersion.properties - logback.xml - src/main/webapp/WEB-INF/ - StrolchBootstrap.xml - runtime - config/ - PrivilegeConfig.xml - PrivilegeRoles.xml - PrivilegeUsers.xml - StrolchConfiguration.xml - StrolchPolicies.xml - data/ - StrolchModel.xsd - defaultModel.xml - templates.xml - temp/ A few notes to the resource files:\n The ENV.properties file is filtered by maven and the environment to load is written in it using the environment variable strolch.env. The appVersion.properties file is also filtered by maven and allows to reflect on the version of this app at runtime. The logback.xml file configures logging using SLF4j and Logback.  The StrolchBootstrap.xml file is used to configure Strolch\u0026rsquo;s environment and root directory. For a webapp it can be annoying to store Strolch\u0026rsquo;s configuration inside the webapp, which is why we can define an absolute path where the configuration is kept. In the following example we keep it in the root of the sources:\n\u0026lt;?xml version=\u0026#34;1.0\u0026#34; encoding=\u0026#34;UTF-8\u0026#34;?\u0026gt; \u0026lt;StrolchBootstrap\u0026gt; \u0026lt;env id=\u0026#34;dev.eitchpc\u0026#34; default=\u0026#34;true\u0026#34;\u0026gt; \u0026lt;root\u0026gt;/home/eitch/src/git/strolch-bookshop/runtime\u0026lt;/root\u0026gt; \u0026lt;environment\u0026gt;dev\u0026lt;/environment\u0026gt; \u0026lt;/env\u0026gt; \u0026lt;/StrolchBootstrap\u0026gt; Here we define two environments, but the both redefine the environment to dev. This is because we want this app to start on two different machines with different user home directories. See the profiles in the POM as to how these environments are activated using a environment property strolch.env.\nIn this next step we\u0026rsquo;ll create Strolch\u0026rsquo;s configuration at the location we defined in the StrolchBootstrap.xml file. Strolch\u0026rsquo;s configuration contains of three directories: config, data and temp. config contains static files which usually aren\u0026rsquo;t changed, data contains model files in XML format and temp is used at runtime for any temporary files, e.g. storing active sessions.\nThe configuration as well as the model has been described on Strolch\u0026rsquo;s documentation web page, we\u0026rsquo;ll just provide you with the files for the bookshop:\nPrivilegeConfig.xml\n\u0026lt;?xml version=\u0026#34;1.0\u0026#34;

A few notes on the configuration:\n  Note how there are three users. Jill is a user with currently no privileges as it\u0026rsquo;s role definition is empty. Admin can do everything, and the agent user is a system user which can also do everything.\n  There is one realm defined in the RealmHandler component which references the defaultModel.xml file in the data directory. This file then includes the currently still empty templates.xml file.\n  We have defined a global environment, but are using the dev environment. The dev environment includes the definitions in the global environment.\n  In PrivilegeConfig.xml we have enabled persistence of sessions, so you will be needing the unlimited JCE libraries for your JVM.\nWhen you restart the server, you don\u0026rsquo;t need to log back in, if your session is still alive.\n  In PrivilegeRoles.xml there seems to be a lot of boilerplate. One thing about a highly configurable system is that sometimes the configuration is bigger. In this case we have opted to have the configuration shown and not use default values which you don\u0026rsquo;t see, so that privilege access is clearly seen.\n  Your project is now ready to be imported into your favourite IDE. We have used both IntelliJ and Eclipse so this is up to you.\nNow that we have a configuration, it is time to have Strolch started when the WAR is deployed and started. In your IDE create a new class as follows:\nStartupListener.java\npackage li.strolch.bookshop.web; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; import javax.servlet.annotation.WebListener; import java.io.InputStream; import li.strolch.agent.api.StrolchAgent; import li.strolch.agent.api.StrolchBootstrapper; import li.strolch.utils.helper.StringHelper; import org.slf4j.Logger; import org.slf4j.LoggerFactory; @WebListener public class StartupListener implements ServletContextListener { private static final Logger logger = LoggerFactory.getLogger(StartupListener.class); private static final String APP_NAME = \u0026#34;Bookshop\u0026#34;; private StrolchAgent agent; @Override public void contextInitialized(ServletContextEvent sce) { logger.info(\u0026#34;Starting \u0026#34; + APP_NAME + \u0026#34;...\u0026#34;); long start = System.currentTimeMillis(); try { String boostrapFileName = \u0026#34;/WEB-INF/\u0026#34; + StrolchBootstrapper.FILE_BOOTSTRAP; InputStream bootstrapFile = sce.getServletContext().getResourceAsStream(boostrapFileName); StrolchBootstrapper bootstrapper = new StrolchBootstrapper(StartupListener.class); this.agent = bootstrapper.setupByBoostrapFile(StartupListener.class, bootstrapFile); this.agent.initialize(); this.agent.start(); } catch (Throwable e) { logger.error(\u0026#34;Failed to start \u0026#34; + APP_NAME + \u0026#34; due to: \u0026#34; + e.getMessage(), e); throw e; } long took = System.currentTimeMillis() - start; logger.info(\u0026#34;Started \u0026#34; + APP_NAME + \u0026#34; in \u0026#34; + (StringHelper.formatMillisecondsDuration(took))); } @Override public void contextDestroyed(ServletContextEvent sce) { if (this.agent != null) { logger.info(\u0026#34;Destroying \u0026#34; + APP_NAME + \u0026#34;...\u0026#34;); try { this.agent.stop(); this.agent.destroy(); } catch (Throwable e) { logger.error(\u0026#34;Failed to stop \u0026#34; + APP_NAME + \u0026#34; due to: \u0026#34; + e.getMessage(), e); throw e; } } logger.info(\u0026#34;Destroyed \u0026#34; + APP_NAME); } } Now configure your IDE to start the web project, and then once it has started, you should see the following in the logs:\nBookshop:dev All 8 Strolch Components started. Took 44ms. Strolch is now ready to be used. Have fun =)) This log tells us the name of the app as defined in the StrolchConfiguration.xml file as well as which environment was loaded. Further we can see that 8 components were configured and started.\nThis concludes the initial setup of a new Strolch project. We can now go ahead and start building the business logic.\n"},{"uri":"https://strolch.li/documentation/","title":"Documentation","tags":[],"description":"","content":"Overview Strolch\u0026rsquo;s documentation has only just begun, but as more and more details of the implementation in Strolch are fixed, more documentation can be created and will be available here.\nCurrently we have the following topics of discussion:\n Architecture   Model   Do and Don\u0026#39;t   Runtime Configuration   Realms   Components   Services and Commands   Searches   Queries   Transactions   Policies   Observers   Versioning   Reports   Privileges   "},{"uri":"https://strolch.li/documentation/model/","title":"Model","tags":[],"description":"","content":"Model Before we dive into the entire model, let\u0026rsquo;s show an example and how it would be modelled in Strolch and use in Strolch:\nThe model has four entities, which will be modelled using 3 Resources and 1 Order object.

Further best practice is to use a parameters ParameterBag, with one or more parameters, modelling the fields. There is API support to not have to always type the parameters bag id. Note that in this example the Type of all the elements is Template. Strolch has API support to create a clone of these elements, so that they have a unique id, and the proper type for persistence. The Product element has three parameters: description, color and form. In this case they are all of type String. Further the relations ParameterBag defines the relationships, i.e. the product knows its articles. Note how the relation is first defined in a relations ParameterBag and that the Parameter has Interpretation=\u0026quot;Resource-Ref\u0026quot; Uom=\u0026quot;Product\u0026quot; attributes. Strolch has API support for this, making it trivial to retrieve a dependency. The Article element has two parameters description and barcode. Further it has a reference to its Product. The Order element doesn\u0026rsquo;t model the date and state fields as parameters, as these are inherently part of an Order element. The Order does define two references to customer and articles. A special case is the quantities ParameterBag. This bag of parameters is used to store the per article quantity for this order. With ParameterBags, you can eliminate the use of simple aggregate classes, as is commonly used in object-oriented programming. The Customer element models an address ParameterBag to store the address of a customer. Using a separate bag allows for further more direct fields to stored on the default parameters bag.  Now that we have a basic understanding of te model, it is of far more interest in how to create and interact with these elements at runtime. The following listing will perform simple operations:\npublic class Example { public static void main(String[] args) { // keep IDs for later use  String dafalganId; String dafalgan1Id; String dafalgan2Id;

\u0026lt;/Activity\u0026gt; Let\u0026rsquo;s explain a few things:\n  The Book entity is a Resource object and only contains the description and the current quantity in stock.\n  The Account entity is a Resource and contains the address and further details of the user, and with the user parameter the username is defined, thus referencing the real user.\n  The UserCart entity is a Resource and has a reference to the account Resource.\nNote how the reference is done using a StringParameter, where Interpretation, UOM and the value is set in a specific manner.\n   The UserCart entity is a Resource and references books using a special ParameterBag with the type set to Book, the actual type of the book entity. Each Parameter is of type Float and the ID of the parameter is the ID of the book, and the value is the quantity that the user would like to purchase.\nThere will only be one cart per user/account.\n  The PurchaseOrder entity is an Order object, and is basically a copy of the UserCart entity. This is the confirmed purchase order for the contents of a cart, and can then be used for reports on how much of which book was sold.\n  The FromStock entity is an Activity object and defines the process we will go through when delivering a purchase to a user.\nNote how the activity has a ParameterBag objectives with a duration parameter. This defines for this activity how long each Action should execute. This can be overridden in each Action and can help to plan how much effort goes into the delivering of each PurchaseOrder.\n Further note how the activity has three special actions (validate, package and send) on which a ResourceType and ResourceId are defined. Actions are always performed on a Resource, as the referenced Resource defines the behaviour of the action through defined Policy objects.\n   For each book which will be purchased, an Action will be created of type Consume. In the template this is defined by a template Action with the id Consume and will later be changed accordingly.\n  Since we are referencing resources from actions in the activity, we need to add these as well, but not as templates. They can be added to the defaultModel.xml file:\n\u0026lt;Resource Id=\u0026#34;validation\u0026#34; Name=\u0026#34;Validation Resource\u0026#34; Type=\u0026#34;Validation\u0026#34;\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;key:ValidationExecution\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ConfirmationPolicy\u0026#34; Value=\u0026#34;key:DefaultConfirmation\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; \u0026lt;Resource Id=\u0026#34;packaging\u0026#34; Name=\u0026#34;Packaging Resource\u0026#34; Type=\u0026#34;Packaging\u0026#34;\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;key:PackagingExecution\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ConfirmationPolicy\u0026#34; Value=\u0026#34;key:DefaultConfirmation\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; \u0026lt;Resource Id=\u0026#34;sending\u0026#34; Name=\u0026#34;Sending Resource\u0026#34; Type=\u0026#34;Sending\u0026#34;\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;key:SendingExecution\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ConfirmationPolicy\u0026#34; Value=\u0026#34;key:DefaultConfirmation\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; What should now be noted by these three new Resources is that they have Policy definitions:\n ExecutionPolicy → defines how an action on this resource is executed by referencing an ExecutionPolicy implementation. ConfirmationPolicy → defines behaviour to be performed on every state change of an action being performed on this resource by referencing an ConfirmationPolicy implementation.  Currently these resources reference policies which don\u0026rsquo;t exist. We will resolve this issue later, when we implement the execution of the activity.\nThis concludes the model definition. In the next step we\u0026rsquo;ll start creating services and commands for our model.\n"},{"uri":"https://strolch.li/plc/","title":"PLC","tags":[],"description":"","content":"Overview Using Strolch as a PLC has certain advantages and disadvantages. The following is a list of advantages:\n Same programming model and language for server and PLC PLC has the same privilege handling as in Strolch Simulating down to the PLC level is easily possible for easier testing of server logic  Of course using the Java language as a PLC has its limitations, we have manage to use it for customers and are satisfied with the result. What follows is a description in how to set up your own Strolch based PLC.\nCheckout the code at GitHub\nStrolch PLC is also deployed to Maven Central. Current version is 1.0.7.\nCurrently, we have the following topics of discussion:\n Architecture   Example Set-Up   "},{"uri":"https://strolch.li/tutorial/crud-book/","title":"CRUD Book","tags":[],"description":"","content":"Preparation Since Books are central to the bookshop, we\u0026rsquo;ll first create the CRUD REST API for them. The API will be as follows:\nGET ../rest/books?query=,offset=,limit= GET ../rest/books/{id} POST ../rest/books PUT ../rest/books/{id} DELETE ../rest/books/{id} Thus corresponding with querying, getting, creating, updating and removing of books. So let\u0026rsquo;s go ahead and add these REST APIs to our project.\nOur project is using JAX-RS 2.0 as the API and Jersey 2.x as the implementation, thus first we need to configure JAX-RS. Thus create the following class:\n@ApplicationPath(\u0026#34;rest\u0026#34;) public class RestfulApplication extends ResourceConfig { public RestfulApplication() { // add strolch resources  register(AuthenticationService.class); register(ModelQuery.class); register(Inspector.class); // add project resources by package name  packages(BooksResource.class.getPackage().getName()); // filters  register(AuthenticationRequestFilter.class, Priorities.AUTHENTICATION); register(AccessControlResponseFilter.class); register(AuthenticationResponseFilter.class); register(HttpCacheResponseFilter.class); // log exceptions and return them as plain text to the caller  register(StrolchRestfulExceptionMapper.class); // the JSON generated is in UTF-8  register(CharsetResponseFilter.class); RestfulStrolchComponent restfulComponent = RestfulStrolchComponent.getInstance(); if (restfulComponent.isRestLogging()) { register(new LoggingFeature(java.util.logging.Logger.getLogger(LoggingFeature.DEFAULT_LOGGER_NAME), Level.SEVERE, LoggingFeature.Verbosity.PAYLOAD_ANY, Integer.MAX_VALUE)); property(ServerProperties.TRACING, \u0026#34;ALL\u0026#34;); property(ServerProperties.TRACING_THRESHOLD, \u0026#34;TRACE\u0026#34;); } } } As we add new resources they will be automatically since we register the entire package.\nNow add the books resource class:\n@Path(\u0026#34;books\u0026#34;) public class BooksResource { } Search The first service we\u0026rsquo;ll add is to query, or search for the existing books. The API defines three parameters, with which the result can be controlled. The method can be defined as follows:\n@Path(\u0026#34;books\u0026#34;) public class BooksResource { @GET @Produces(MediaType.APPLICATION_JSON) public Response query(@Context HttpServletRequest request, @QueryParam(\u0026#34;query\u0026#34;) String queryS, @QueryParam(\u0026#34;offset\u0026#34;) String offsetS, @QueryParam(\u0026#34;limit\u0026#34;) String limitS) { // TODO  } } To fill this method we need a few things. First let\u0026rsquo;s define a constants class where we keep String constants which we used in the model file:\npublic class BookShopConstants { public static final String TYPE_BOOK = \u0026#34;Book\u0026#34;; } As this tutorial progresses, more and more constants will be added here. This class helps with two issues: Through the constants we can easily reason over where certain fields, and types are used and of course String literals in code are a rather bad thing.\nIn Strolch there are multiple way to access objects. The old way was using Queries, the new search API is much more fluent and easier to read and write. The search API, as well as the deprecated query API allows us to implement privilege validation and thus one should create corresponding classes for each type of search. Book entities are Resources, thus we will be creating a ResourceSearch. The search is for Resources of type Book thus the resulting search looks as follows:\npublic class BooksSearch\u0026lt;U\u0026gt; extends ResourceSearch\u0026lt;U\u0026gt; { public BookSearch() { types(TYPE_BOOK); } public BookSearch stringQuery(String value) { if (isEmpty(value)) return this; // split by spaces  value = value.trim(); String[] values = value.split(\u0026#34; \u0026#34;); // add where clauses for id, name and description  where(id().containsIgnoreCase(values) //  .or(name().containsIgnoreCase(values)) //  .or(param(BAG_PARAMETERS, PARAM_DESCRIPTION).containsIgnoreCase(values))); return this; } } Note how we added a special stringQuery(String)-method. This method defines where a search string entered by the user will be used to match a book. In this case for id, name and the description parameter.\nSo that our users can call this query, we must give them this as a privilege. This is done by adding the full class name to the PrivilegeRoles.xml file as follows:\n... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.search.StrolchSearch\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;Allow\u0026gt;internal\u0026lt;/Allow\u0026gt; \u0026lt;Allow\u0026gt;li.strolch.bookshop.search.BookSearch\u0026lt;/Allow\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;/Role\u0026gt; ...  Note: The internal allow value is a special privilege which is used internally when a service or something performs internal queries. This means that a service can perform a query for object to which the user might not have access, but without which the service could not be completed. We will use this in a later stage.\n Now we have all parts we need to implement the query method. The method will include opening a transaction, instantiating the search, executing the search, and returning the result:\n@Path(\u0026#34;books\u0026#34;) public class BooksResource { @GET @Produces(MediaType.APPLICATION_JSON) public Response query(@Context HttpServletRequest request, @QueryParam(\u0026#34;query\u0026#34;) String queryS, @QueryParam(\u0026#34;offset\u0026#34;) String offsetS, @QueryParam(\u0026#34;limit\u0026#34;) String limitS) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request .getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); int offset = StringHelper.isNotEmpty(offsetS) ? Integer.parseInt(offsetS) : 0; int limit = StringHelper.isNotEmpty(limitS) ? Integer.parseInt(limitS) : 0; // open the TX with the certificate, using this class as context  Paging\u0026lt;Resource\u0026gt; paging; try (StrolchTransaction tx = RestfulStrolchComponent.getInstance() .openTx(cert, getClass())) { // perform a book search  paging = new BookSearch() //  .stringQuery(queryS) //  .search(tx) //  .orderByName(false) //  .toPaging(offset, limit); } ResourceVisitor\u0026lt;JsonObject\u0026gt; visitor = new StrolchRootElementToJsonVisitor() .flat().asResourceVisitor(); return ResponseUtil.toResponse(paging, e -\u0026gt; e.accept(visitor)); } }  Note: We automatically transform the Resource objects to JSON using the StrolchElementToJsonVisitor. By calling the method .flat()-method we have a more compact JSON format. Paging is handled by a util class.\n The helper class ResponseUtil takes care of creating the JsonObject and the proper page. As a rule we use the format where we return two fields: msg is a dash if all is ok, otherwise an error message will be present. Data is always in the data field. This is just a personal taste, and can be changed to one\u0026rsquo;s own taste.\nGet We have all we need now to implement the GET method:\n@GET @Path(\u0026#34;{id}\u0026#34;) @Produces(MediaType.APPLICATION_JSON) public Response get(@Context HttpServletRequest request, @PathParam(\u0026#34;id\u0026#34;) String id) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // open the TX with the certificate, using this class as context  try (StrolchTransaction tx = RestfulStrolchComponent.getInstance().openTx(cert, getClass())) { // get the book  Resource book = tx.getResourceBy(BookShopConstants.TYPE_BOOK, id); if (book == null) return ResponseUtil.toResponse(Status.NOT_FOUND, \u0026#34;Book \u0026#34; + id + \u0026#34; does not exist!\u0026#34;); // transform to JSON  JsonObject bookJ = book.accept(new StrolchRootElementToJsonVisitor().flat()); // return  return ResponseUtil.toResponse(StrolchRestfulConstants.DATA, bookJ); } }  Note how we simply retrieve the book as a Resource from the TX. This is a good moment to familiarize yourself with the API of the StrolchTransaction. There are methods to retrieve elements, and also perform searches. We will use more of these methods later.\n Further it can be noted that a simple retrieval isn\u0026rsquo;t validated against the user\u0026rsquo;s privileges, the user is authenticated, which is enough for the moment.\nCreate To create a new book we need to implement a Service. This service will be called CreateBookService. A Service always has a ServiceArgument and a ServiceResult. Our service will use the JsonServiceArgument and the JsonServiceResult. The implementation of the POST method is as follows:\n@POST @Produces(MediaType.APPLICATION_JSON) public Response create(@Context HttpServletRequest request, String data) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // parse data to JSON  JsonObject jsonData = JsonParser.parseString(data).getAsJsonObject(); // instantiate the service with the argument  CreateBookService svc = new CreateBookService(); JsonServiceArgument arg = svc.getArgumentInstance(); arg.jsonElement = jsonData; // perform the service  ServiceHandler serviceHandler = RestfulStrolchComponent.getInstance().getServiceHandler(); JsonServiceResult result = serviceHandler.doService(cert, svc, arg); // return depending on the result state  if (result.isOk()) return ResponseUtil.toResponse(StrolchRestfulConstants.DATA, result.getResult()); return ResponseUtil.toResponse(result); }  Note: We return the created object again as JSON in its own data field.\n The service is implemented as follows:\npublic class CreateBookService extends AbstractService\u0026lt;JsonServiceArgument, JsonServiceResult\u0026gt; { @Override protected JsonServiceResult getResultInstance() { return new JsonServiceResult(); } @Override public JsonServiceArgument getArgumentInstance() { return new JsonServiceArgument(); } @Override protected JsonServiceResult internalDoService(JsonServiceArgument arg) throws Exception { // open a new transaction, using the realm from the argument, or the certificate  Resource book; try (StrolchTransaction tx = openArgOrUserTx(arg)) { // get a new book \u0026#34;instance\u0026#34; from the template  book = tx.getResourceTemplate(BookShopConstants.TYPE_BOOK); // map all values from the JSON object into the new book element  book.accept(new FromFlatJsonVisitor(arg.jsonElement.getAsJsonObject()).ignoreBag(BAG_RELATIONS)); // save changes  tx.add(book); // notify the TX that it should commit on close  tx.commitOnClose(); } // map the return value to JSON  JsonObject result = book.accept(new StrolchElementToJsonVisitor().flat()); // and return the result  return new JsonServiceResult(result); } }  Note: For the authenticated user to be able to perform this service, we must add it to their privileges:\n ... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; ... \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;Allow\u0026gt;li.strolch.bookshop.service.CreateBookService\u0026lt;/Allow\u0026gt; \u0026lt;/Privilege\u0026gt; ... \u0026lt;/Role\u0026gt; ... Update Updating of a book is basically the same as the creation, we just use PUT, verify that the book exists and give the user the privilege.\nPUT Method:\n@PUT @Path(\u0026#34;{id}\u0026#34;) @Produces(MediaType.APPLICATION_JSON) public Response update(@Context HttpServletRequest request, @PathParam(\u0026#34;id\u0026#34;) String id, String data) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // parse data to JSON  JsonObject jsonData = JsonParser.parseString(data).getAsJsonObject(); // instantiate the service with the argument  UpdateBookService svc = new UpdateBookService(); JsonServiceArgument arg = svc.getArgumentInstance(); arg.objectId = id; arg.jsonElement = jsonData; // perform the service  ServiceHandler serviceHandler = RestfulStrolchComponent.getInstance().getServiceHandler(); JsonServiceResult result = serviceHandler.doService(cert, svc, arg); // return depending on the result state  if (result.isOk()) return ResponseUtil.toResponse(StrolchRestfulConstants.DATA, result.getResult()); return ResponseUtil.toResponse(result); } Update Service:\npublic class UpdateBookService extends AbstractService\u0026lt;JsonServiceArgument, JsonServiceResult\u0026gt; { @Override protected JsonServiceResult getResultInstance() { return new JsonServiceResult(); } @Override public JsonServiceArgument getArgumentInstance() { return new JsonServiceArgument(); } @Override protected JsonServiceResult internalDoService(JsonServiceArgument arg) throws Exception { // verify same book  DBC.PRE.assertEquals(\u0026#34;ObjectId and given Id must be same!\u0026#34;, arg.objectId, arg.jsonElement.getAsJsonObject().get(Json.ID).getAsString()); // open a new transaction, using the realm from the argument, or the certificate  Resource book; try (StrolchTransaction tx = openArgOrUserTx(arg)) { // get the existing book  book = tx.getResourceBy(BookShopConstants.TYPE_BOOK, arg.objectId, true); // map all values from the JSON object into the new book element  book.accept(new FromFlatJsonVisitor(arg.jsonElement.getAsJsonObject()).ignoreBag(BAG_RELATIONS)); // save changes  tx.update(book); // notify the TX that it should commit on close  tx.commitOnClose(); } // map the return value to JSON  JsonObject result = book.accept(new StrolchElementToJsonVisitor().flat()); // and return the result  return new JsonServiceResult(result); } } Privilege\n... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; ... \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; ... \u0026lt;Allow\u0026gt;li.strolch.bookshop.service.UpdateBookService\u0026lt;/Allow\u0026gt; ... \u0026lt;/Privilege\u0026gt; ... \u0026lt;/Role\u0026gt; ... Remove To remove a book, we need a DELETE method, a remove service and the associated privilege.\nDELETE Method:\n@DELETE @Path(\u0026#34;{id}\u0026#34;) @Produces(MediaType.APPLICATION_JSON) public Response update(@Context HttpServletRequest request, @PathParam(\u0026#34;id\u0026#34;) String id) { // this is an authenticated method call, thus we can get the certificate from the request:  Certificate cert = (Certificate) request.getAttribute(StrolchRestfulConstants.STROLCH_CERTIFICATE); // instantiate the service with the argument  RemoveBookService svc = new RemoveBookService(); StringServiceArgument arg = svc.getArgumentInstance(); arg.value = id; // perform the service  ServiceHandler serviceHandler = RestfulStrolchComponent.getInstance().getServiceHandler(); ServiceResult result = serviceHandler.doService(cert, svc, arg); // return depending on the result state  return ResponseUtil.toResponse(result); } Remove Service:\npublic class RemoveBookService extends AbstractService\u0026lt;StringServiceArgument, ServiceResult\u0026gt; { @Override protected ServiceResult getResultInstance() { return new ServiceResult(); } @Override public StringServiceArgument getArgumentInstance() { return new StringServiceArgument(); } @Override protected ServiceResult internalDoService(StringServiceArgument arg) throws Exception { // open a new transaction, using the realm from the argument, or the certificate  try (StrolchTransaction tx = openArgOrUserTx(arg)) { // get the existing book  Resource book = tx.getResourceBy(BookShopConstants.TYPE_BOOK, arg.value, true); // save changes  tx.remove(book); // notify the TX that it should commit on close  tx.commitOnClose(); } // and return the result  return ServiceResult.success(); } } Privilege:\n... \u0026lt;Role name=\u0026#34;User\u0026#34;\u0026gt; ... \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; ... \u0026lt;Allow\u0026gt;li.strolch.bookshop.service.RemoveBookService\u0026lt;/Allow\u0026gt; ... \u0026lt;/Privilege\u0026gt; ... \u0026lt;/Role\u0026gt; ... Notes One should now see a pattern emerge:\n The REST API delegates to the Services, or Searches, with the exception of the retrieval of a single object by id. Services should do initial validation of the input. Not much validation was done here, but more could be done. Commands are reusable objects to perform recurring work. Searches and Services are privileged actions for which a user must have the privilege to perform the action.  The book services are quite simple, but as more requirements arise, it should be easy to implement them in the service layer. Thus should a service be required to be performed by an integration layer, then they can simply call the services, since the input is defined and validation is done there (i.e. NOT in the REST API).\nThis concludes the CRUD of books.\n"},{"uri":"https://strolch.li/documentation/do-and-donts/","title":"Do and Don&#39;t","tags":[],"description":"","content":"This page discusses things you should and shouldn\u0026rsquo;t do when using Strolch The following is a simple list of do\u0026rsquo;s and don\u0026rsquo;ts:\n  1 Service per use-case, should mostly delegate to Commands.\n  Commands implement use-cases or parts of it, and are thus reusable.\n  Subclass ResourceSearch, OrderSearch and ActivitySearch when implementing use-case specific search - this allows privilege checking.\n  One Transaction at a time - no TX inside of another TX.\n  Commands are added to TXs and performed on close: tx.addCommand(Command) and then tx.commitOnClose()\n  Only access ElementMaps if really no other way, mostly use tx.get*By(), tx.findBy() and searches - if a specific get is missing, then add the method to StrolchTransaction and send a pull request!\n  Use tx.stream*() methods to iterate over all elements, if you don\u0026rsquo;t want to use a search.\n  Don\u0026rsquo;t write logic in REST API beans.

The configuration are files located in the ..config/ folder, and the model are files located in the ../data folder.\nIn an absolute minimal configuration, the Strolch runtime requires the following folder structure:\n ../config/  ../StrolchConfiguration.xml → configures the Strolch agent ../PrivilegeConfig.xml → configures user management ../PrivilegeUsers.xml → contains the users in an XML based user management file ../PrivilegeRoles.xml → contains the roles and privileges in an XML based user management    StrolchConfiguration.xml The StrolchConfiguration.xml file configures the Strolch agent. The StrolchConfiguration.xml defines the following:\n \u0026lt;StrolchConfiguration\u0026gt; root element \u0026lt;env id=\u0026quot;xxx\u0026quot;\u0026gt; different environments with the possibility of having a global environment for configuration valid in multiple environments.  \u0026lt;Runtime\u0026gt; element which defines the agents name and a few other properties e.g. locale and verbose: \u0026lt;applicationName\u0026gt; the agent\u0026rsquo;s name \u0026lt;Properties\u0026gt;  \u0026lt;locale\u0026gt; the agent\u0026rsquo;s internal locale for log messages etc. \u0026lt;verbose\u0026gt; the logging level for some internal logging. (Logging is mostly done using log4j over slf4j)   \u0026lt;Component\u0026gt; elements for each component used in the agent. A component is configured by defining the following child elements:   \u0026lt;name\u0026gt; the name of the component, use when defining dependencies between components. The name is mostly set to the simple name of the interface of the component\n  \u0026lt;api\u0026gt; the full class name to the interface of the component. During runtime this interface will be used to access the component e.g.:\nServiceHandler svcHandler = agent.getContainer().getComponent(ServiceHandler.class);\n  \u0026lt;impl\u0026gt; the full class name of the concrete implementation of the component. During initialization this class will be instantiated and registered under the component name and interface. This class must extend the class li.strolch.agent.api.StrolchComponent\n  \u0026lt;depends\u0026gt; any number of these elements, where the content is the name of another component, on which this component depends. Depending components are initialized and started after the component they depend on and are stopped and destroyed before\n  \u0026lt;Properties\u0026gt;\n  \u0026lt;...\u0026gt; any number of properties which the component requires. The element\u0026rsquo;s name will be the key with which the value can be accessed at runtime.\n      When a property is missing, and the component has a hard coded default value, then when the component is initialized, the use of the default value and its key is logged. This makes it easy to see which new properties can be configured. Should the component not define a default value, then the component will thrown an exception on initialization. In this case it can be a good moment to read the JavaDoc (or source code) for the component in question to see how it is configured.\n Privilege Configuration In Strolch authentication and authorization is baked in. To open a transaction, and thus access the Strolch model, a Certificate object is required, which means the user has been authenticated and possibly authorized.\nThe PrivilegeConfig.xml defines the following:\n \u0026lt;Privilege\u0026gt; root element  \u0026lt;Container\u0026gt; configures the individual Privilege components  \u0026lt;Parameters\u0026gt; base configuration properties for Privilege \u0026lt;EncryptionHandler\u0026gt; configures the hashing algorithms and other encryption specific configuration \u0026lt;PersistenceHandler\u0026gt; configures the persistence of the roles and users \u0026lt;UserChallengeHandler\u0026gt; configures a challenge handler so that a user can reset their password. The default challenge handler is the li.strolch.privilege.handler.MailUserChallengeHandler which sends a challenge to the user\u0026rsquo;s defined e-mail address. \u0026lt;SsoHandler\u0026gt; the SSO Handler is used to implement a SingleSignOn and can be used to start a session using a LDAP token, etc. There is no default implementation as this is project specific.   \u0026lt;Policies\u0026gt; configures the available privilege policies at runtime, the name is referenced from the model file    The PrivilegeUsers.xml and PrivilegeRoles.xml define the users and roles and is used when in PrvilegeConfig.xml the PersistenceHandler is set to ch.eitchnet.privilege.handler.XmlPersistenceHandler:\n \u0026lt;Users\u0026gt; configures all users  \u0026lt;User\u0026gt; configures a specific user  \u0026lt;Firstname\u0026gt; configures a user\u0026rsquo;s first name \u0026lt;Lastname\u0026gt; configure a user\u0026rsquo;s last name \u0026lt;State\u0026gt; configures the user\u0026rsquo;s state, see li.strolch.privilege.model.UserState \u0026lt;Locale\u0026gt; configure the user\u0026rsquo;s locale \u0026lt;Roles\u0026gt; configures the user\u0026rsquo;s roles  \u0026lt;Role\u0026gt; adds a role to the user \u0026lt;Properties\u0026gt; configures user specific properties. What properties are used is not specified and is dependent on the concrete agent  \u0026lt;Property\u0026gt; defines a single property       \u0026lt;Roles\u0026gt; configures all roles  \u0026lt;Role\u0026gt; configures a specific role  \u0026lt;Privilege\u0026gt; configures a specific privilege for this role  \u0026lt;AllAllowed\u0026gt; if set to true, then defines that all values associated with this privilege are allowed \u0026lt;Allow\u0026gt; defines one allowed value for this privilege \u0026lt;Deny\u0026gt; defines one denied value for this privilege          Implementing a StrolchComponent Implementing a strolch component requires an interface, which defines the component\u0026rsquo;s API and a concrete class which implements the interface and extends the class StrolchComponent.\nThe StrolchComponent class adds the state model to the class, which transitions as follows:\nUNDEFINED =\u0026gt; SETUP =\u0026gt; INITIALIZED =\u0026gt; STARTED \u0026lt;=\u0026gt; STOPPED =\u0026gt; DESTROYED\nComponents can switch between STARTED and STOPPED, but once DESTROYED no further state change is possible. The component\u0026rsquo;s state is changed by changes to the agent\u0026rsquo;s lifecycle.\nA component\u0026rsquo;s state is changed by a call to the appropriate method on the component, override the methods as necessary. Note that it is good practice that the initialize()-method is used to get all the configuration properties, and that they should there be evaluated and that the method so return quickly. The start()-method is called after the agent\u0026rsquo;s initialization and should be where additional threads are started. Correctly implementing these methods allows to quickly detect a wrongly configured agent, which might take longer to start for whatever reason.\nThe following shows a basic implementation of a component on the basis of a post initializer (a component which performs some actions in its start()-method which should be done after everything else is started in the agent).\npublic class SimplePostInitializer extends StrolchComponent implements PostInitializer { public SimplePostInitializer(ComponentContainer container, String componentName) { super(container, componentName); } @Override public void initialize(ComponentConfiguration configuration) { // do some initialization, validate configuration values, etc.  // now call super, to update state  super.initialize(configuration); } @Override public void start() { // start any threads, or perform long running start work  // now call super, to update state  super.start(); } @Override public void stop() { // stop threads and timers, but be ready to start again  // now call super, to update state  super.stop(); } @Override public void destroy() { // destroy this component, release all resources and don\u0026#39;t worry about  // being called to start again now call super, to update state  super.destroy(); } } The new component would then be registered in the StrolchConfiguration.xml as follows:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;...\u0026#34;\u0026gt; ... \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;SimplePostInitializer\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.agent.api.PostInitializer\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.documentation.SimplePostInitializer\u0026lt;/impl\u0026gt; \u0026lt;/Component\u0026gt; ... \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; And can be access at runtime using:\nPostInitializer postInitializer = getContainer().getComponent(PostInitializer.class); Starting the agent When a Strolch runtime is started, then the root path to the runtime configuration must be passed. In Java this is done by calling:\nStrolchAgent agent = new StrolchAgent(); agent.setup(environment, rootPath); agent.initialize(); agent.start(); In Servlet 3.0 applications one would implement the javax.servlet.ServletContextListener interface, add the @WebListener annotation to the class and in the contextInitialized()-method start Strolch:\nString realPath = sce.getServletContext().getRealPath(\u0026#34;/WEB-INF\u0026#34;); String environment = StrolchEnvironment.getEnvironmentFromEnvProperties(pathF); this.agent = new StrolchAgent(); this.agent.setup(environment, new File(realPath)); this.agent.initialize(); this.agent.start(); "},{"uri":"https://strolch.li/tutorial/","title":"Tutorial","tags":[],"description":"","content":"Let\u0026rsquo;s build a bookshop!

A PlcGwService instance will be notified and can then decide on an action. In an execution model with Activities, the PlcNotificationListener interface can be implemented, or the PlcExecutionPolicy can be directly extended.\nOn the PLC side, the PlcGwClientHandler is optional if no agent is required. The PlcHandler initializes the model and connections. The Plc class is Strolch agnostic and manages the connections and notifies PlcListener instances on changes coming from the underlying connections. The PlcService implementations implement business logic, and can also be notified on updates from connections.\n"},{"uri":"https://strolch.li/documentation/realms/","title":"Realms","tags":[],"description":"","content":"Realms Realms implement multi-tenant capabilities. A Strolch agent can have an arbitrary number of realms configured and each realm has its own persistence configuration, allowing to separate mandates completely.\nA realm can run in one of the following modes:\n EMPTY This is a transient data store mode, where no model changes are persisted - they are only kept in memory. When the Strolch agent is started, this realm is empty as no data is loaded. TRANSIENT This is the same as EMPTY, but with the difference that when the Strolch agent is started, a model file is parsed and the in-memory realm is populated with the elements parsed from the model file. CACHED In this mode, all data is stored in-memory, and any changes made are written back to the persistence layer. This allows for fast in-memory qeuries, but makes sure no data is lost when the agent is restarted.  Realms are mostly hidden from a developer as a StrolchTransaction exposes all important operations needed to access Strolch objects. A developer will however need to configure the realms for their specific project. If the project only requires one realm, then the defaultRealm can be used, where the developer only is required to configure the mode and any relevant model file.\nIf the mode is CACHED, then the PersistenceHandler component is required to be configured, so that the DAOs know how to access the underlying database.\nThe configuration in the StrolchConfiguration.xml file is as follows:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;dev\u0026#34;\u0026gt; ... \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;RealmHandler\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.agent.api.RealmHandler\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.agent.impl.DefaultRealmHandler\u0026lt;/impl\u0026gt; \u0026lt;depends\u0026gt;PrivilegeHandler\u0026lt;/depends\u0026gt; \u0026lt;!-- if CACHED: --\u0026gt; \u0026lt;!--depends\u0026gt;PersistenceHandler\u0026lt;/depends--\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;!-- one of EMPTY, TRANSIENT, CACHED--\u0026gt; \u0026lt;dataStoreMode\u0026gt;TRANSIENT\u0026lt;/dataStoreMode\u0026gt; \u0026lt;dataStoreFile\u0026gt;StrolchModel.xml\u0026lt;/dataStoreFile\u0026gt; \u0026lt;/Properties\u0026gt; \u0026lt;/Component\u0026gt; ... \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; Multi-Realm A multi-realm configuration would be as follows.\nNote how the defaultRealm is still enabled, and has its configuration as before.

An agent is basically a container for classes extending StrolchComponent with a life cycle. These classes mostly implement an interface which describes the operations that are supported by the component.\nThe following represents a list of the most used components:\n RealmHandler: li.strolch.agent.impl.DefaultRealmHandler PrivilegeHandler: li.strolch.runtime.privilege.DefaultStrolchPrivilegeHandler EnumHandler: li.strolch.runtime.query.enums.DefaultEnumHandler PolicyHandler: li.strolch.policy.DefaultPolicyHandler ServiceHandler: li.strolch.service.api.DefaultServiceHandler StrolchSessionHandler: li.strolch.rest.DefaultStrolchSessionHandler PersistenceHandler: multiple implementations PostInitializer: project specific implementation MailHandler: li.strolch.handler.mail.SmtpMailHandler  A component has a life-cycle, which is governed by the Agent\u0026rsquo;s own life-cycle. The life-cycle is as follows:\nsetup -\u0026gt; initialize -\u0026gt; start \u0026lt;-\u0026gt; stop -\u0026gt; destroy The setup step is used to instantiate the component, the initialize step is used to validate configuration parameters, and the run step is used to start the component, i.e. start threads, etc. The stop step stops these threads and also allows the component to be started again. The destroy step destroys the instance and makes it unusable anymore, i.e. shutdown of the agent.\nEach component has its own configuration parameters. A component is registered in the StrolchConfiguration.xml file with a\n name api class name implementation class name configuration parameters any required dependencies  The dependencies is an important feature as the dependencies of a component are always started before the actual component.\nExample Component implementation and configuration By example of the MailHandler we shall show how a strolch component would be implemented.\nFirst define an interface:\npublic interface MailHandler { void sendMail(String subject, String text, String recipient); } Then implement a concrete MailHandler:\npublic class SmtpMailHandler extends StrolchComponent implements MailHandler { // TODO instance fields with configuration properties to send the mail  public SmtpMailHandler(ComponentContainer container, String componentName) { super(container, componentName); } @Override public void initialize(ComponentConfiguration configuration) throws Exception { // TODO store any properties needed from the configuration  super.initialize(configuration); } @Override public void sendMail(String subject, String text, String recipient) { // TODO send the e-mail using SMTP, or send asynchronously  } } Now that the component is written, it must be registered on the component, so that it is loaded when the agent is started. For this the StrolchConfiguration.xml file must be modified to include a component element:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;dev\u0026#34;\u0026gt; ... \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;MailHandler\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.handler.mail.MailHandler\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.handler.mail.SmtpMailHandler\u0026lt;/impl\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;username\u0026gt;test\u0026lt;/username\u0026gt; \u0026lt;password\u0026gt;test\u0026lt;/password\u0026gt; \u0026lt;hostName\u0026gt;localhost\u0026lt;/hostName\u0026gt; ... \u0026lt;/Properties\u0026gt; \u0026lt;/Component\u0026gt; ... \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; Now when the agent is started, the component can be retrieved and used. E.g from inside a Service:\npublic class MyService extends AbstractService\u0026lt;ServiceArgument, ServiceResult\u0026gt; { @Override protected ServiceResult internalDoService(ServiceArgument arg) throws Exception { MailHandler mailHandler = getComponent(MailHandler.class); mailHandler.sendMail(\u0026#34;My Subject\u0026#34;, \u0026#34;Hello World\u0026#34;, \u0026#34;test@test.ch\u0026#34;); } } "},{"uri":"https://strolch.li/documentation/services-and-commands/","title":"Services and Commands","tags":[],"description":"","content":"Services and Commands Services are written to implement a specific use-case.

The use-case can be abstract e.g., AddResourceService or very specific e.g. CreatePatientService.\nShould the use-case be re-usable in different scenarios, then commands should implement the logic, and the services should then execute the commands. E.g. The CreatePatientService would use a CreatePatientResourceCommand and then use an AddResourceCommand in a single transaction, so that the task of creating the actual Patient Resource can be re-used somewhere else.\nServices extend the abstract class AbstractService and then implement the method internalDoService(ServiceArgument).

Strolch searches are implemented using the StrolchSearch class and one of its concrete implementations: ResourceSearch, OrderSearch, ActivitySearch.\nA Strolch element always has two identifiers: Type and Id. The type is important as it classifies an element. So if a car and a house would be modelled in Strolch, then those would both be a Resource, but one of type Car and the other of type House. Both would have different parameters. Thus when searching for objects, the first thing to do is define the type of object being searched.\nThe Strolch search API is very expressive and offers multiple ways to perform the same search. The search API consists of three components: The search classes, the search expressions and the search predicates. The concept was taken from the Apache Camel project.\nThere are four main search classes:\n RootElementSearch - search for any of Resource, Order or Activity elements ResourceSearch - search for Resources OrderSearch - search for Orders ActivitySearch - search for Activities  No search is useful without a where clause, which are called search expressions. When writing a search, there are multiple ways to add such where clauses. Either\n override the define()-method in your sub class and add the where clauses by calling the where() method, or define special methods on the class e.g. byColor() which also calls the where()-method to add a search expression, or directly call the where()-method after instantiating a search.  When extending the class, then the search expressions are available as methods on the super class, otherwise you can statically import them from ExpressionsSupport .\nAnd of course a where clause needs operators, which are called search predicates. Just as search expressions are available in sub classes, so are search predicates and can also be statically imported through PredicatesSupport .\nExamples of search expressions with search predicates follow:\nResourceSearch search=new ResourceSearch(); // predicate either as parameter, or chained search.where(id().isEqualTo(\u0026#34;myId\u0026#34;)); search.where(id(isEqualTo(\u0026#34;myId\u0026#34;))); // negating search.where(id(isEqualTo(\u0026#34;myId\u0026#34;)).not()); search.where(param(\u0026#34;bagId\u0026#34;,\u0026#34;paramId\u0026#34;).isIn(Arrays.asList(\u0026#34;red\u0026#34;,\u0026#34;blue\u0026#34;,\u0026#34;green\u0026#34;))); search.where(paramNull(\u0026#34;bagId\u0026#34;,\u0026#34;paramId\u0026#34;))); // boolean operations search.where(id(isEqualTo(\u0026#34;myId\u0026#34;)) // \t.or(name(isEqualTo(\u0026#34;myName\u0026#34;)))); Note how the predicates can be chained to the search expression, or passed as a parameter to the expression.\nIn addition to using predefined search search expressions, one can also just pass a lambda expression which performs a custom filter:\npersonSearch.where(person -\u0026gt; person.getName().length() == 3); See the StrolchSearchTest for many ways in which you can implement tests.\nNote that strolch searches requires privileges, thus when you use a strolch search, add it to the role of the user in PrivilegeRoles.xml:\n \u0026lt;Privilege name=\u0026#34;li.strolch.search.StrolchSearch\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;Allow\u0026gt;internal \u0026lt;/Allow\u0026gt; \u0026lt;!-- internal used for when the search is done in an internal service --\u0026gt; \u0026lt;Allow\u0026gt;li.strolch.bookshop.search.BookSearch\u0026lt;/Allow\u0026gt; \u0026lt;/Privilege\u0026gt; "},{"uri":"https://strolch.li/documentation/queries/","title":"Queries","tags":[],"description":"","content":"Queries The Query API is deprecated and the search API should be used instead.\n As is custom for every framework, querying the model must be possible. Strolch queries are implemented using the StrolchQuery interface and one of its concrete implementations: ResourceQuery, OrderQuery, ActivityQuery.\nA Strolch element always has two identifiers: Type and Id. The type is important as it classifies an element. So if a car and a house would be modelled in Strolch, then those would both be a Resource, but one of type Car and the other of type House. Both would have different parameters.\nThus one of the inputs for every query is it\u0026rsquo;s type, which is defined as the navigation. It is said that we navigate to the Cars, or Houses. Thus when instantiating a ResourceQuery, pass the navigation to the type of Resource as well. Same applies for Orders and Activities.\nFurther input for a StrolchQuery are the selections. These selections get translated into RDBMS WHERE clauses. Selections support boolean operations thus allowing for complex querying.\nStrolchQueries also support Ordering and object transformation. Following classes provide the most used scenarios:\n OrderById OrderByName OrderByParameter *ToDomVisitor *ToSaxVisitor *ToJsonVisitor *ToFlatJsonVisitor  Example: Query all resources of type Car:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.withAny(); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car, order by Name and transform to JSON:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;JsonObject\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;, new ResourceToJsonVisitor(), new OrderByName()); query.withAny(); List\u0026lt;JsonObject\u0026gt; cars = tx.doQuery(query); } the previous example can also be written as follows:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;JsonObject\u0026gt; query = new ResourceQuery\u0026lt;\u0026gt;(); query.setNavigation(new StrolchTypeNavigation(\u0026#34;Car\u0026#34;)); query.setResourceVisitor(new ResourceToJsonVisitor()); query.withAny(); List\u0026lt;JsonObject\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car with color blue:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.with(ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es())); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car which are not blue:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.not(ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es())); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car with color blue or yellow:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); query.or().with( ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es()), ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;yellow\u0026#34;, StringMatchMode.es())); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } Example: Query all resources of type Car with color blue or yellow owned by Jill:\ntry (StrolchTransaction tx = openTx()) { ResourceQuery\u0026lt;Resource\u0026gt; query = ResourceQuery.query(\u0026#34;Car\u0026#34;); StringParameterSelection owner = ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;owner\u0026#34;, \u0026#34;Jill\u0026#34;, StringMatchMode.es()); OrSelection colors = new OrSelection().with( ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;blue\u0026#34;, StringMatchMode.es()), ParameterSelection.stringSelection(\u0026#34;parameters\u0026#34;, \u0026#34;color\u0026#34;, \u0026#34;yellow\u0026#34;, StringMatchMode.es())); query.and().with(owner, colors); List\u0026lt;Resource\u0026gt; cars = tx.doQuery(query); } "},{"uri":"https://strolch.li/development/","title":"Development","tags":[],"description":"","content":"Prerequisites To start developing Strolch you need an installed:\n Java JDK 17 Apache Maven 3.x  Building Strolch Note: You don\u0026rsquo;t have to build Strolch if you want to use the version on Maven central, but if you need a snapshot version, or the release you want isn\u0026rsquo;t on central, then go ahead and build Strolch.\n Building Strolch is just a few lines:\ngit clone https://github.com/strolch-li/strolch.git cd strolch mvn clean install -DskipTests  Note: To run the tests you will need to configure the PostgreSQL Databases. See the README in the module.\n After running the Maven build, you will have a full build of all Strolch projects. Now you can start modifying the projects, and add your own features, or, far more interesting, start developing your projects using the Strolch agent.\nCreating a Strolch App To create your own Strolch App, you can use Maven\u0026rsquo;s archetype generation. There are two versions, one is a simple Java App which you can use to directly access the Strolch runtime, and the second is to create a Java Web App, which is the usual way to run Strolch runtimes.\nNote: you need to have installed Strolch to your local maven repo, otherwise the archetype won\u0026rsquo;t be available.\n Creating a Java Strolch Web App The following shows the maven command to create the new maven project.

Please download the relevant platform\u0026rsquo;s package, unpack it, and add the bin directory to your path variable.\nOnce NodeJS is installed, then you can prepare the web dependencies:\ncd src/main/webapp/ npm install bower -g npm install gulp -g npm install gulp cd ../../..  Note: Whenever the bower.json is changed then you should again call npm install inside the webapp folder.\n Building and running the WAR Building the WAR uses the package maven goal, but to have the optimized WAR use the release profile.\nTo run this WAR, we must configure the path of Strolch\u0026rsquo;s runtime in the StrolchBootstrap.xml file, by updating the following block, setting the absolute path to the runtime from the new project:\n\u0026lt;env id=\u0026#34;test\u0026#34; default=\u0026#34;true\u0026#34;\u0026gt; \u0026lt;root\u0026gt;/absolute/path/to/\u0026amp;lt;my-artifactId\u0026amp;gt;/runtime\u0026lt;/root\u0026gt; \u0026lt;environment\u0026gt;test\u0026lt;/environment\u0026gt; \u0026lt;/env\u0026gt; Now we can build the project using the configured environment:\nmvn clean package -Prelease -Dstrolch.env=test Now copy the WAR from the target/ directory to the webapps/ directory of your Tomcat 9.x installation.

The following are simple examples:  StartupPlcService\nimport li.strolch.persistence.api.StrolchTransaction; import li.strolch.plc.core.PlcHandler; import li.strolch.plc.core.PlcService; public class StartupPlcService extends PlcService { public static final String PLC = \u0026#34;PLC\u0026#34;; public static final String STARTED = \u0026#34;Started\u0026#34;; public static final String STOPPED = \u0026#34;Stopped\u0026#34;; public StartupPlcService(PlcHandler plcHandler) { super(plcHandler); } @Override public void start(StrolchTransaction tx) { send(PLC, STARTED); super.start(tx); } @Override public void stop() { send(PLC, STOPPED); super.stop(); } } ConveyorPlcService\nimport java.util.concurrent.ScheduledFuture; import java.util.concurrent.TimeUnit; import li.strolch.plc.core.PlcHandler; import li.strolch.plc.core.PlcService; import li.strolch.plc.model.PlcAddress; public class ConveyorPlcService extends PlcService { public static final int BOX_TRANSFER_DURATION = 30; private static final String R_CONVEYOR_01 = \u0026#34;Conveyor01\u0026#34;; private static final String A_START_BUTTON = \u0026#34;StartButton\u0026#34;; private static final String T_MOTOR_ON = \u0026#34;MotorOn\u0026#34;; private static final String T_MOTOR_OFF = \u0026#34;MotorOff\u0026#34;; private static final String A_BOX_DETECTED = \u0026#34;BoxDetected\u0026#34;; private boolean motorOn; private ScheduledFuture\u0026lt;?\u0026gt; motorStopTask; public ConveyorPlcService(PlcHandler plcHandler) { super(plcHandler); } @Override public void handleNotification(PlcAddress address, Object value) { String resource = address.resource; String action = address.action; if (!resource.equals(\u0026#34;Conveyor01\u0026#34;)) throw new IllegalStateException(\u0026#34;Unexpected resource \u0026#34; + resource); boolean active = (boolean) value; if (action.equals(A_START_BUTTON)) { if (active) { logger.info(\u0026#34;Start button pressed.

To have less configuration files and make it easier to reconfigure at runtime, this data is stored in normal Strolch Resources.\nIn this example we will use simple Raspberry Pi GPIOs. For convenience, and also when sharing I/O definitions with external partners, it is easier to use a CSV file to define the I/Os and then use the PlcAddressGenerator to generate and validate the model.\nFor this purpose in this example, we will use one conveyor with 2 inputs and 1 output. The CSV file should have the following content:\n  Description,Type,SubType,Device,Pin,Resource,Action1,Action2,Connection,DeviceId Material Flow,Group,,,,,,,,MaterialFlow Conveyor 1,Input,Pin,,4,Conveyor,Occupied,,raspiBcmGpioInput Conveyor 1,Input,Pin,,17,Conveyor,BoxDetected,,raspiBcmGpioInput Conveyor 1,Output,Pin,,18,Conveyor,MotorOn,MotorOff,raspiBcmGpioOutput The CSV headers are as follows:\n Description → a simple description for this PlcAddress Type →  Group → Must be the first line and generates a PlcLogicalDevice, all succeeding lines are grouped to this device. Add additional to group further devices Input → defines a boolean input Output → defines a boolean output Virtual → defines a virtual address which has no corresponding hardware connection. Used for internal communication. DataLogicScanner → defines an address to read barcodes from a DataLogic Scanner. The actions must be left empty as the keys Barcode (address), On and Off (telegrams) will be generated.   SubType → For Input and Output types →  DevPin, DevPin0 → Generates the address as \u0026lt;Connection\u0026gt;.\u0026lt;Device\u0026gt;.\u0026lt;Pin\u0026gt;. DevPin0 decrements the Device and Pin values by one. Pin → Generates the address as \u0026lt;Connection\u0026gt;.\u0026lt;Pin\u0026gt;.   For Virtual types →  Boolean String   Device → Device number Pin → The pin number on the device Resource → The resource ID with which to notify the agent Action1 → The action ID Action2 → The second action ID if required Connection → The ID of the PlcConnection with which this I/O is attached DeviceId → For type Group: Set the ID of this PlcLogicalDevice being generated  When you use this file as input for the PlcAddressGenerator, then it will generate PlcLogicalDevice, PlcAddress and PlcTelegram elements:\n\u0026lt;StrolchModel\u0026gt;

E.g. The action On would send true, and Off would send false. This is semantics, and is defined in each project depending on the hardware.\n Copy the file plc-state.xml to your runtime and reference it by use of a \u0026lt;IncludeFile file=\u0026quot;plc-state.xml\u0026quot; /\u0026gt; element.

A transaction is opened for a realm, and grants access to the model of the agent. Transactions are implemented as a Java try-with-resources by implementing the AutoCloseable interface. This makes it trivial to understand the scope of a transaction.\nTransactions handle the following:\n Opening and closing database connections Releasing locks to strolch elements, if tx.lock(StrolchRootElement) or tx.lock(Locator) was called Performing Commands by executing them in the added order, and validating them first. Exception handling Auditing Updating observers  When a transaction is opened, it is by default read-only, i.e. does not perform any commands when it is closed. Should the TX perform commands, then it is important to call tx.commitOnClose(), but only at the end of the work, so that exception handling can properly work if something goes wrong.\nStrolchTransaction offers a myriad of methods:\n find element by its Locator get methods for elements by type and id, or using a StringParameter or StringListParameter references methods to add, update or remove elements assert privilege access get a new element by its template check if an element exists by type and id get streams for elements add commands for execution  Transactions are opened by accessing the realm, but there are convenience methods depending on the use-case:\n In Services: by calling one of the openTx()-methods In Commands: Transactions are already open, use method tx() to get instance. REST API: RestfulStrolchComponent.openTx()  Note: don\u0026rsquo;t open a new TX inside a TX for the same realm!\n Important is to always open the transaction as a try-with-resource block and to define if the TX should commit, or not:\ntry (StrolchTransaction tx = openTx(...)) { // read lock our object  Locator ferrariLoc = Resource.locatorFor(\u0026#34;Car\u0026#34;, \u0026#34;ferrari\u0026#34;); tx.lock(ferrariLoc); // find a car by locator  Resource ferrari = tx.findElement(ferrariLoc); // get a car by ID  Resource opel = tx.getResourceBy(\u0026#34;Car\u0026#34;, \u0026#34;opel\u0026#34;, true); // modify ball  opel.setName(\u0026#34;Opel Corsa\u0026#34;); tx.update(opel); // get by string reference  StringParameter ownerP = ferrari.getParameter(\u0026#34;relations\u0026#34;, \u0026#34;owner\u0026#34;, true); Resource owner = tx.getResourceBy(ownerP, true); // get by string list reference  StringListParameter previousOwnersP = opel.getParameter(\u0026#34;relations\u0026#34;, \u0026#34;previousOwners\u0026#34;, true); List\u0026lt;Resource\u0026gt; previousOwners = tx.getResourcesBy(previousOwnersP, true); // check resource exists  if (tx.hasResource(\u0026#34;Car\u0026#34;, \u0026#34;audi\u0026#34;)) { Resource audi = tx.getResourceBy(\u0026#34;Car\u0026#34;, \u0026#34;audi\u0026#34;, true); // assert has privilege to remove a car  tx.assertHasPrivilege(Operation.REMOVE, audi); // remove the car  tx.remove(audi); } // iterate all cars  tx.streamResources(\u0026#34;Car\u0026#34;).forEach(car -\u0026gt; { logger.info(\u0026#34;Car: \u0026#34; + car.getId()); }); // commit if TX was changed  if (tx.needsCommit()) tx.commitOnClose(); } "},{"uri":"https://strolch.li/documentation/policies/","title":"Policies","tags":[],"description":"","content":"Policies Policies are an integral part when writing business logic in Strolch. In many cases it would suffice to write all such logic in Services and Commands, but as soon as behaviour can change, depending on the element being accessed, then this would quickly lead to many if/else blocks.\nSince writing large if/else blocks is not maintanable in the long run, Strolch offers a different approach. All Strolch elements can store Policy definitions. This is a simple key/value store where the key defines the type of policy, and the value references the policy to use.\nCurrently there are two ways to reference a policy in Strolch, either via a key which defines a further lookup in the PolicyHandler, or directly as the name of the class to instantiate.\nUsing policies in Strolch gives the additional possibility of easily changing the behaviour at runtime, as a Service and/or Command would delegate the behaviour to the currently configured policy on the releveant element.\nPolicies are implemented by defining an abstract class and extends StrolchPolicy. This abstract class then defines the API of the actual policy. A concrete class then extends this abstract class and implements the concrete methods.\nPolicies are registered on Resources, Orders, Activities and Actions. The following shows defining two policies on a Resource, a PlanningPolicy, an ExecutionPolicy in XML:\n\u0026lt;Resource Id=\u0026#34;myResource\u0026#34; Name=\u0026#34;My Resource\u0026#34; Type=\u0026#34;MyType\u0026#34;\u0026gt; ... \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;PlanningPolicy\u0026#34; Value=\u0026#34;key:SimplePlanning\u0026#34; /\u0026gt; \u0026lt;Policy Type=\u0026#34;ExecutionPolicy\u0026#34; Value=\u0026#34;java:li.strolch.policytest.TestSimulatedExecutionPolicy\u0026#34; /\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt;  Note how the PlanningPolicy has a value of key:SimplePlanning and the ExecutionPolicy defines a reference to an actual class.\n To use the PolicyHandler, it must be configured in the StrolchConfiguration.xml as follows:\n\u0026lt;StrolchConfiguration\u0026gt; \u0026lt;env id=\u0026#34;dev\u0026#34;\u0026gt; \u0026lt;Component\u0026gt; \u0026lt;name\u0026gt;PolicyHandler\u0026lt;/name\u0026gt; \u0026lt;api\u0026gt;li.strolch.policy.PolicyHandler\u0026lt;/api\u0026gt; \u0026lt;impl\u0026gt;li.strolch.policy.DefaultPolicyHandler\u0026lt;/impl\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;readPolicyFile\u0026gt;true\u0026lt;/readPolicyFile\u0026gt; \u0026lt;policyConfigFile\u0026gt;StrolchPolicies.xml\u0026lt;/policyConfigFile\u0026gt; \u0026lt;/Properties\u0026gt; \u0026lt;/Component\u0026gt; \u0026lt;/env\u0026gt; \u0026lt;/StrolchConfiguration\u0026gt; And this policy handler implementation requires a file where the lookups for the policies is defined, e.g.:\n\u0026lt;StrolchPolicies\u0026gt; \u0026lt;PolicyType Type=\u0026#34;PlanningPolicy\u0026#34; Api=\u0026#34;li.strolch.policytest.TestPlanningPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;SimplePlanning\u0026#34; Class=\u0026#34;li.strolch.policytest.TestSimplePlanningPolicy\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; \u0026lt;PolicyType Type=\u0026#34;ExecutionPolicy\u0026#34; Api=\u0026#34;li.strolch.execution.policy.ExecutionPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;SimulatedExecution\u0026#34; Class=\u0026#34;li.strolch.execution.policy.RandomDurationExecution\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; \u0026lt;PolicyType Type=\u0026#34;ConfirmationPolicy\u0026#34; Api=\u0026#34;li.strolch.policytest.TestConfirmationPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;NoConfirmation\u0026#34; Class=\u0026#34;li.strolch.policytest.TestNoConfirmationPolicy\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; \u0026lt;/StrolchPolicies\u0026gt; Now at runtime we can access the policies:\npublic class MyService extends AbstractService\u0026lt;ServiceArgument, ServiceResult\u0026gt; { @Override protected ServiceResult internalDoService(ServiceArgument arg) throws Exception { try (StrolchTransaction tx = openArgOrUserTx(arg)) { Resource res = tx.getResourceBy(\u0026#34;MyType\u0026#34;, \u0026#34;myTestResource\u0026#34;); PlanningPolicy planningPolicy = tx.getPolicy(res, PlanningPolicy.class); planningPolicy.plan(...); ExecutionPolicy executionPolicy = tx.getPolicy(res, ExecutionPolicy.class); executionPolicy.toExecution(...); tx.commitOnClose(); } return ServiceResult.success(); } } "},{"uri":"https://strolch.li/documentation/observers/","title":"Observers","tags":[],"description":"","content":"Observers All changes done in a Strolch transaction are recorded and then propagated to any registered observers.\nThe observer feature is opt-in and is configured for each realm.

In Strolch a report is defined by using its own model, i.e. a Report is a Resource of type Report.\nA report consists of the following parts:\n policy definition, thus allowing extensions basic configuration like base object type, order direction, etc. column definitions joins ordering definition filters  An example of a report is as follows:\n\u0026lt;Resource Id=\u0026#34;stockReport\u0026#34; Name=\u0026#34;Stock Report\u0026#34; Type=\u0026#34;Report\u0026#34;\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;parameters\u0026#34; Name=\u0026#34;parameters\u0026#34; Type=\u0026#34;Parameters\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;objectType\u0026#34; Index=\u0026#34;20\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Object Type\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;Player\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;descending\u0026#34; Name=\u0026#34;Descending order\u0026#34; Type=\u0026#34;Boolean\u0026#34; Value=\u0026#34;true\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;ordering\u0026#34; Name=\u0026#34;Ordering\u0026#34; Type=\u0026#34;Ordering\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;name\u0026#34; Name=\u0026#34;Name\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;noTeamFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:Equals\u0026#34; Value=\u0026#34;!\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Slot\u0026#34; Value=\u0026#34;Bags/relations/team\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;columns\u0026#34; Name=\u0026#34;Display Columns\u0026#34; Type=\u0026#34;Display\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;name\u0026#34; Name=\u0026#34;Player\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;birthDate\u0026#34; Name=\u0026#34;Birth date\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;Bags/parameters/birthDate\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;team\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;joins\u0026#34; Name=\u0026#34;Joins\u0026#34; Type=\u0026#34;Joins\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;Team\u0026#34; Index=\u0026#34;10\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;Player\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;Policies\u0026gt; \u0026lt;Policy Type=\u0026#34;ReportPolicy\u0026#34; Value=\u0026#34;java:li.strolch.report.policy.GenericReport\u0026#34;/\u0026gt; \u0026lt;/Policies\u0026gt; \u0026lt;/Resource\u0026gt; This report\n shows all Resources of type player (parameter objectType) → marks the object type to be show in the filter criteria (default), and that its sorting index is at 20. orders the report by player\u0026rsquo;s name (parameter bag ordering) filters out all players with no team assigned (parameter bag noTeamFilter) defines three columns: Player, Birth date, Team (paramger bag columns) joins in the resource of type Team Uses the GenericReport class to generate the report  GenericReport The default generic report implemented in Strolch has the following features and options:\nParameters The parameters bag can contain the following parameters:\n  objectType → the base type of object to get the input for the report. This means that the Interpretation is set to one of:\n Resource-Ref Order-Ref Activity-Ref  and that the UOM and value of the parameter is set to the type of element with which to retrieve the elements from the strolch model.\n  descending → boolean flag to define if sorting is in descending order\n  allowMissingColumns → flag to define if no exception should be thrown if a column is missing\n  dateRangeSel → defines a lookup parameter to use as a date range selector. This requires input when executing the report\n  Note: that the attributes Hidden and Index define the visibility and sorting index as filter criteria respectively.\n Lookups Many of the features of the generic report rely on looking up a value on the referenced element. The following shows the ways that a lookup can be performed:\n $id → lookup the ID of the element $name → lookup the name of the element $type → lookup the type of the element $date → lookup the date of the element (only possible on Order and Activity elements) $state → lookup the state of the element (only possible on Order and Activity elements) Bags/\u0026lt;bag_id\u0026gt;/\u0026lt;param_id\u0026gt; → a lookup on the selected element by bag ID and parameter ID $search:\u0026lt;parent_ref_id\u0026gt;:Bags/\u0026lt;bag_id\u0026gt;/\u0026lt;param_id\u0026gt; → searches for a parameter with the given bag and parameter, and if it does not exist, looks for the parent with the given parent_ref_id on the element. This allows a recursive search up a tree of elements which all have the same parameter referencing a parent. relations bag  Note: these definitions are set as the value of a Parameter, and the Interpretation and UOM of the parameter is used to find the element on which to perform the lookup. I.e. the following definition:\n \u0026lt;Parameter Id=\u0026#34;name\u0026#34; Name=\u0026#34;Player\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Player\u0026#34; Value=\u0026#34;$name\u0026#34;/\u0026gt; defines that we want to lookup the name of the resource of type Player.\nOrdering Ordering, i.e sorting is done by adding the parameter bag with the id ordering and each parameter defines a column to order by. The sequence of the ordering is defined by the index value assigned to each parameter.\nFiltering Filtering use additional Strolch Policies which implement the operator function. I.e. performing an equals, etc. The following ReportFilterPolicy are available and should be added in your StrolchPolicies.xml file:\n\u0026lt;StrolchPolicies\u0026gt; ... \u0026lt;PolicyType Type=\u0026#34;ReportFilterPolicy\u0026#34; Api=\u0026#34;li.strolch.report.policy.ReportFilterPolicy\u0026#34;\u0026gt; \u0026lt;Policy Key=\u0026#34;GreaterThan\u0026#34; Class=\u0026#34;li.strolch.report.policy.GreaterThanReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;LessThan\u0026#34; Class=\u0026#34;li.strolch.report.policy.LessThanReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;Equals\u0026#34; Class=\u0026#34;li.strolch.report.policy.EqualsReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;Contains\u0026#34; Class=\u0026#34;li.strolch.report.policy.ContainsReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;IsIn\u0026#34; Class=\u0026#34;li.strolch.report.policy.IsInReportFilter\u0026#34;/\u0026gt; \u0026lt;Policy Key=\u0026#34;ValueRef\u0026#34; Class=\u0026#34;li.strolch.report.policy.ValueRefReportFilter\u0026#34;/\u0026gt; \u0026lt;/PolicyType\u0026gt; ... \u0026lt;/StrolchPolicies\u0026gt; From this we can see that we can perform a GreaterThan, LessThan and Equals filtering. These filters can also be negated by prefixing the filter value with an exclamation mark (!).\nA special case for the filter values are filters on dates. If you are filtering on a date, then you can use the special operator now(). This filter will use the current date and time and will add/subtract the ISO8601 period passed as an argument to the operator.\nThe following shows examples of these filters:\n\u0026lt;ParameterBag Id=\u0026#34;minQtyFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:GreaterThan\u0026#34; Value=\u0026#34;10\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Product\u0026#34; Value=\u0026#34;Bags/parameters/quantity\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;notEmptyFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:Equals\u0026#34; Value=\u0026#34;!\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;Bags/relations/team\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; \u0026lt;ParameterBag Id=\u0026#34;threeMonthsAgoFilter\u0026#34; Name=\u0026#34;Filter\u0026#34; Type=\u0026#34;Filter\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;policy\u0026#34; Name=\u0026#34;Filter Policy\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;ReportFilterPolicy\u0026#34; Uom=\u0026#34;key:LessThan\u0026#34; Value=\u0026#34;now(-P3M)\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;fieldRef\u0026#34; Name=\u0026#34;Field reference\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;FromStock\u0026#34; Value=\u0026#34;$date\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt;  Note: One parameter defines which policy gets used and the key:\u0026lt;name\u0026gt; value references a policy defined in the StrolchPolicies.xml file. Further the lookup is defined in the fieldRef parameter.\n Joins To add columns from data which is not on the element denoted by the base object type, we can join further elements. This is done by adding the parameter bag joins and then each parameter references an element to join. The joining is done as follows:\n The Intepretation and UOM define which object we want to join, i.e. resource of type foo The value of the parameter defines the type of element on which to find the reference The join ordering is not relevant, as the tree is traversed accordingly At least one join must reference the base object type The lookup of the join is done by finding a parameter with any ID, which has the same Interpretation and UOM as the join definition The attributes Hidden and Index define the visibility and sorting index as filter criteria respectively.  Thus the following:\n\u0026lt;ParameterBag Id=\u0026#34;joins\u0026#34; Name=\u0026#34;Joins\u0026#34; Type=\u0026#34;Joins\u0026#34;\u0026gt; \u0026lt;Parameter Id=\u0026#34;Team\u0026#34; Index=\u0026#34;10\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Team\u0026#34; Value=\u0026#34;Player\u0026#34;/\u0026gt; \u0026lt;Parameter Id=\u0026#34;Country\u0026#34; Index=\u0026#34;5\u0026#34; Hidden=\u0026#34;false\u0026#34; Name=\u0026#34;Team\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Country\u0026#34; Value=\u0026#34;Team\u0026#34;/\u0026gt; \u0026lt;/ParameterBag\u0026gt; Performs two joins: First we join a resource of type Team by finding the relevant parameter on the Player resource, and then we lookup a resource of type Country on the previously joined Team resource.\nExecution of Reports To execute a reports, we must instantiate the Report and can then directly generate a JsonObject stream, which we can then pipe to a browser, file, etc.:\nStream\u0026lt;JsonObject\u0026gt; jsonObjectStream = new Report(tx, reportId).doReportAsJson(); If you prefer a CSV report:\ntry (CSVPrinter csvP = new CSVPrinter(new OutputStreamWriter(out), CSVFormat.DEFAULT.withHeader(headers).withDelimiter(\u0026#39;;\u0026#39;))) { // do report without AsJson, and then iterating each row and sending to a CSV writer  report.doReport().forEach(row -\u0026gt; { try { csvP.printRecord(row.valueStream().collect(Collectors.toList())); // add to CSV  } catch (Exception e) { logger.error(\u0026#34;Could not write CSV row\u0026#34;, e); } }); } Filter Criteria Predefining filters is a good start, but in some case you only want a portion of the actual filtered data. For instance if you make a stock report, you might only want one location. This information is dynamic and thus not stored on the report definition.\nTo perform these dynamic filterings, one would call the filter()-method on the report, passing the type of element to be filtered, and to which element IDs to reduce the report data to. The following reduces the report to only return the rows with the product01 Product and location02 Location elements:\nnew Report(tx, \u0026#34;stockReport\u0026#34;) .filter(\u0026#34;Product\u0026#34;, \u0026#34;product01\u0026#34;) .filter(\u0026#34;Location\u0026#34;, \u0026#34;location02\u0026#34;) .doReportAsJson() It is possible to find the possible filter criteria dynamically using the generateFilterCriteria() method.\nDate Range Filtering The last option to filter dynamically is using a date range selector. Define the dateRangeSel lookup parameter, and then set the date range on the instantiated report:\nModel the report in XML:\n\u0026lt;ParameterBag Id=\u0026#34;parameters\u0026#34; Name=\u0026#34;parameters\u0026#34; Type=\u0026#34;Parameters\u0026#34;\u0026gt; ... \u0026lt;Parameter Id=\u0026#34;dateRangeSel\u0026#34; Name=\u0026#34;Date Range Selector\u0026#34; Type=\u0026#34;String\u0026#34; Interpretation=\u0026#34;Resource-Ref\u0026#34; Uom=\u0026#34;Product\u0026#34; Value=\u0026#34;Bags/parameters/expirationDate\u0026#34;/\u0026gt; ... \u0026lt;/ParameterBag\u0026gt; And now call the report in Java:\nDate from = new Date(LocalDate.of(2016, 1, 1).toEpochDay() * 86400000); Date to = new Date(LocalDate.of(2017, 1, 1).toEpochDay() * 86400000); DateRange dateRange = new DateRange().from(from, true).to(to, false); List\u0026lt;JsonObject\u0026gt; result = new Report(tx, \u0026#34;stockReport\u0026#34;) //  .filter(\u0026#34;Product\u0026#34;, \u0026#34;product01\u0026#34;) //  .dateRange(dateRange) //  .doReportAsJson()  Note: See the GenericReportTest for examples.\n "},{"uri":"https://strolch.li/documentation/priviles/","title":"Privileges","tags":[],"description":"","content":"Privileges No framework is complete without user management and privilege validation.

The privileges can overlap, a validation is performed to make sure that the one role doesn\u0026rsquo;t deny and another role allows a specific action.\nAs explained in the Privilege Configuration section, users are defined in the PrivilegeUsers.xml file, and roles are defined in the PrivilegeRoles.xml file.\nLet\u0026rsquo;s assume the following user and role definition:\n\u0026lt;Users\u0026gt; \u0026lt;User userId=\u0026#34;1\u0026#34; username=\u0026#34;jill\u0026#34; password=\u0026#34;$PBKDF2WithHmacSHA512,10000,256$61646d696e$cb69962946617da006a2f95776d78b49e5ec7941d2bdb2d25cdb05f957f64344\u0026#34;\u0026gt; \u0026lt;Firstname\u0026gt;Jill\u0026lt;/Firstname\u0026gt; \u0026lt;Lastname\u0026gt;Someone\u0026lt;/Lastname\u0026gt; \u0026lt;State\u0026gt;ENABLED\u0026lt;/State\u0026gt; \u0026lt;Locale\u0026gt;en-GB\u0026lt;/Locale\u0026gt; \u0026lt;Roles\u0026gt; \u0026lt;Role\u0026gt;AppUser\u0026lt;/Role\u0026gt; \u0026lt;/Roles\u0026gt; \u0026lt;Properties\u0026gt; \u0026lt;Property name=\u0026#34;realm\u0026#34; value=\u0026#34;execution\u0026#34; /\u0026gt; \u0026lt;/Properties\u0026gt; \u0026lt;/User\u0026gt; \u0026lt;/Users\u0026gt; \u0026lt;Roles\u0026gt; \u0026lt;Role name=\u0026#34;AppUser\u0026#34;\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.service.api.Service\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;AllAllowed\u0026gt;true\u0026lt;/AllAllowed\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.model.query.StrolchQuery\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;AllAllowed\u0026gt;true\u0026lt;/AllAllowed\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;Privilege name=\u0026#34;li.strolch.search.StrolchSearch\u0026#34; policy=\u0026#34;DefaultPrivilege\u0026#34;\u0026gt; \u0026lt;AllAllowed\u0026gt;true\u0026lt;/AllAllowed\u0026gt; \u0026lt;/Privilege\u0026gt; \u0026lt;/Role\u0026gt; \u0026lt;/Roles\u0026gt; This configuration contains one user and one role. The user jill has the role AppUser and the role AppUser has three privileges assigned.\nNote how the user\u0026rsquo;s password is configured similar to a unix password definition: Using the dollar sign \u0026amp; first the hashing algorithm is configured ( algorithm, iterations, key length), then the salt, followed by the password hash.\nNote: The password can also still be saved using two separate fields: a salt and password field. This configuration will be immediately changed to the unix form, so won\u0026rsquo;t be described further here.\n Further a user always has a firstname and last name. Optionally a locale can be set, otherwise the system locale is used. The user\u0026rsquo;s state must be defined as one of NEW, ENABLED, DISABLED, EXPIRED or SYSTEM. A user can only authenticate/login with the state ENABLED. A user can have any number of properties, which can then be used at runtime. A user can also reference any number of roles, the assigned privilege can overlap, a global configuration mode defines how duplicate privileges are handled.\nRoles have a name and any number of Privilege definitions. A Privilege has a name, which in many cases is the name of Java class/interface on which an action is being invoked. The policy value defines which policy to use when evaluating the privilege access. The privilege definition is defined in the PrivilegeConfig.xml and is the name of a class to call for privilege validation.\nFurther the privilege definitions can have a AllAllowed boolean flag, or any number of Allow or Deny values. How these values are interpreted is defined in the policy implementation. A policy takes three input parameters:\n PrivilegeContext → supplied by privilege and gives access to the Certificate, thus identifying the user for which privilege access is to be validated. IPrivilege → Contains the privilege values: AllAllowed, Allow and Deny Restrictable → An interface from which the privilege name is retrieved, and the associated value. The value is an object, and is cast to the relevant input in the concrete privilege policy.  The following privilege policies are already implemented:\n DefaultPrivilege → simple policy where the passed Restrictable is expected to return a String value, which is compared with allow and deny values. Internal: RoleAccessPrivilege → policy used for the internal privileges PrivilegeGetRole, PrivilegeAddRole, PrivilegeModifyRole or PrivilegeModifyRole Internal: UserAccessPrivilege → policy used for the internal privileges PrivilegeGetUser, PrivilegeAddUser, PrivilegeRemoveUser, PrivilegeModifyUser, PrivilegeAddRoleToUser, PrivilegeRemoveRoleFromUser, PrivilegeSetUserState, PrivilegeSetUserLocale or PrivilegeSetUserPassword Internal: UserAccessWithSameOrganisationPrivilege → Same as the UserAccessPrivilege but expects the authenticated user to have a property organisation and validates that the user being modified is in the same organisation. Internal: UsernameFromCertificatePrivilege → This policy expects a Restrictable to return the certificate of another authenticated user and is used when modifying an authenticated user, i.e. killing a session, or modifying its current state, e.g. locale etc. Internal: UsernameFromCertificateWithSameOrganisationPrivilege → Same as UsernameFromCertificatePrivilege but expects the authenticated user to have a property organisation and validates that the user being modified is in the same organisation.  Note: As a rule, the sequence is AllAllowed → Allow → Deny → default deny\n "},{"uri":"https://strolch.li/history/","title":"History","tags":[],"description":"","content":"Overview Strolch is an open source component based software agent written in Java and can be compared, in a light sense, with the Java EE stack: Strolch takes care of persistence, implements Services for use cases, Commands as re-usable algorithms and has a parameterized data model.\nStrolch has an intrinsic understanding for mandates, which are called realms so that a single agent can be used to implement applications with multiple users/customers for instance in SaaS environments.\nThe parameterized data model consists of three top level objects, Resources, Orders and Activities. These objects can have any number of ParameterBags which in turn can have any number of Parameters on them. This allows for a very dynamic modelling of data structures including modification at run time. Multiple ready to use Parameter types are already implemented which handle the primitive types in Java including ListParameters for collections of these primitive types.\nOne of the main features of the Strolch agent, is that persistence is handled transparently and the user must not be worried about databases and the likes. Currently there are two implementations for persisting the Strolch model, a PostgreSQL and an XML file persistence. Currently both persistence layers persist the data by converting to XML and storing it into the database. The XML file persistence stores each object in its own file.\nThe agent itself has a small memory footprint and requires very few components to start. For the agent to be useful it needs additional functionality which is implemented in StrolchComponents. Each component is registered via its Java interface on the agent and is bound to the life cycle of the agent. When the agent is started, these components can be retrieved and used to perform any number of functionalities. This is the preferred way to extend the Strolch agent. There are a number of components already implemented, e.g. the ServiceHandler which executes Services in a controlled fashion and can validate authorized access to these services.\nNo software product is complete without a system for authentication and authorization. Strolch implements this by using the Privilege framework which has been written by Robert von Burg. The standard ServiceHandler detects the existence of the PrivilegeHandler and then validates that the user has authorization to perform the service. This framework is implemented as its own Strolch component, thus can be retrieved at any time during execution to perform fine grained and special authorization validation.\nMotivation A question often asked is why create Strolch. What are its benefits in contrast to using Java SE with an OR-Mapper like Hibernate, or using Java EE on JBoss or Glassfish? Especially since many of the features existing in those stacks needed to be re-created in Strolch.\nThe first answer to this question is that those systems are often overly complicated and bloated. Java SE with Hibernate certainly is a viable option when it comes to being light-weightier but Hibernate, even though it is supposed to, often fails to truly help remove the need to really understand an RDBMS. Often enough Hibernate will just get in the way of the most important part of development: writing the business code. Being an OR-Mapper which is supposed to implement all the nitty-gritty details of an RDBMS system, Hibernate, and JPA for that matter, still often has the developer go back to understanding these details.\nStrolch tries a different approach to persistence. Instead of writing pojos/entities, Strolch\u0026rsquo;s model has the concept that each element\u0026rsquo;s attributes are part of a composition pattern: each attribute is its own object and thus can be dynamically changed at runtime, but also makes persistence of such an element generic. Instead of having fixed attributes for a concrete class, these parameters are stored in a map and are accessed through the parameter\u0026rsquo;s ID.\nAssigning an ID to an attribute for accessing of course brings its own downsides, i.e. the parameter might simply not be there, when being accessed. This is certainly an issue that the developer must handle, when implementing a project using Strolch, but allows the developer to not need to worry about persistence, as this is generically handled.\nSince the persistence is generically handled, and Strolch stays lightweight on its requirements at runtime, the developer can quickly get down to what is important for business value: Writing the business logic and the presentation layer. Here too Strolch tries to help the developer by bringing in concepts which are easy to follow: Use cases are implemented as Services, and re-usable business logic is put into Commands.\nThere will be reasons against using Strolch, as there will be against using the Java EE stack, or an OR-Mapper or even the Java ecosystem for that fact. Important is to note, that the concepts behind Strolch are nothing new, but have been implemented in at least two previous proprietary products. Since those products are not accessible to the public, it was decided that a re-implementation might be of use to the programming community at large.\nCurrently, there is at least one company using Strolch in a commercial project which helps drive Strolch\u0026rsquo;s development and further motivates its existence.\nStrolch is an open source project and licensed under the Apache License 2.0.\n##Technology Strolch is written in Java and is programmed against the JDK 8. Strolch runs on any JRE 8 compliant environment. Strolch is tested on the Oracle JRE 8.\n"},{"uri":"https://strolch.li/blog/","title":"Blog","tags":[],"description":"","content":"About The official Strolch blog with news, ideas, and thoughts on using Strolch.\nStrolch is an open source component based software agent written in Java and can be compared, in a light sense, with the Java EE stack: Strolch takes care of persistence, implements Services for use cases, Commands as re-usable algorithms and has a parameterized data model.\nEntries  Strolch PLC now also on Maven Central  Strolch PLC version 1.0.7 has been deployed to Maven Central for easier integration into your projects\n Release of Strolch 1.6.100  The 100. release of the 1.6 branch and a brand new website!\n Strolch Reports  Strolch can do reports!\n Strolch Searches  Strolch queries are deprecated!\n Wow, the many changes!

It\u0026rsquo;s main features are:\n Complete persisted data model:  Parameters and values by time Resources, Orders with arbitrary parameter grouping Activity/Action hierarchy with arbitrary depth Policies for delegation JSON as well as XML transformation Locator API   Transactions with pessimistic locking and optional read-locking Search API Component based Deeply integrated privilege handling Fully in-memory Persisted auditing, versioning, operations log DAOs for file system or PostgreSQL, easily extended Execution framework Service / Command oriented Reporting API configured by Resource objects REST API for data access WebComponents UI for  Inspector Users Roles Operations Log Login Screen Jobs   runs on plain old Java SE  Strolch Intro It is a different framework to Spring and other similar type of Java frameworks, as the model is defined as an abstract model, where you always have the same three types of objects: Resources, Orders and Activities. The fields are mapped as Parameter objects, of which the important primitives are available.\nThe nice part about this framework is, that you can be up and ready in a matter of minutes, and start building your project immediately in that you open your favourite XML editor and start modelling your data.\nOnce your data is defined, you write your business logic in the form of Services, Commands and Searches. There are many predefined services and commands to manipulate the object model, so that you write your own services when you need to enforce special business rules.\nThrough the use of Policy objects, you decouple algorithms from your object model, so that at runtime you can change the behaviour, or easily implement different behaviour depending on your use-case. For instance you might have a simple billing service which performs a few preparatory steps, and then calls the configured billing policy to execute the billing depending on the customer, the warehouse, etc.\nAnd of course persistence is as simple as configuring the persistence handler, pointing to your RDBMS and then setting the mode to CACHED. For you as a developer there is no more thinking in terms of SQL etc., as this is completely hidden from the developer. There is even a simple file persistence layer if you are running IoT devices.\nThe runtime can be just about anything. Usually it is run inside an Apache Tomcat instance as a webapp, as a WEB UI has been required for all current Strolch projects. You could just as well use a main class. Accessing the Strolch Agent remotely is usually done through REST.\nStrolch is being actively developed, and customers constantly give us reasons to improve and extend the framework. There is a Polymer Inspector component which makes it easy to see and manipulate the actual data. The new Search API makes it really easy to query your data.\nYes, Strolch is different, but the concept has come out of the planning and execution segment, and has been refined over the years until it has become what it is today.\nAPI Check out the API page to see how to use Strolch.\nMore to motivation etc.\n"},{"uri":"https://strolch.li/categories/","title":"Categories","tags":[],"description":"","content":""},{"uri":"https://strolch.li/tags/","title":"Tags","tags":[],"description":"","content":""}]

This book store will
 be without a UI, but we will do everything using REST APIs, which should make it
 easy to add a UI later using whatever framework suits one most.</p><p>The book store will have the following features:</p><ul><li>The store owner can add, update and remove books</li><li>The store owner can edit the stock quantity</li><li>Users can view a list of books</li><li>Users can add books to a virtual cart</li><li>Users can create and verify an account using an e-mail address</li><li>Users can submit an order for the books in their cart</li><li>The store owner can see the orders by state (pending, preparing, sent)</li><li>The store owner can update the state of an order (preparing, sent)</li><li>Notify the user when the order is sent</li></ul><p>The code to the book can be downloaded
 from <a href=https://github.com/strolch-li/strolch-bookshop target=_blank>GitHub</a> and will be updated
-as this tutorial is updated.</p><p>The tutorial consists of the following parts:<ul class="children children-li"><li><a href=/tutorial/configuration/>Configuration</a></li><li><a href=/tutorial/model/>Model</a></li><li><a href=/tutorial/crud-book/>CRUD Book</a></li></ul></p><footer class=footline></footer></div></div><div id=navigation><a class="nav nav-prev" href=/plc/example-set-up/ title="Example Set-Up"><i class="fa fa-chevron-left"></i></a><a class="nav nav-next" href=/tutorial/configuration/ title=Configuration style=margin-right:0><i class="fa fa-chevron-right"></i></a></div></section><div style=left:-1000px;overflow:scroll;position:absolute;top:-1000px;border:none;box-sizing:content-box;height:200px;margin:0;padding:0;width:200px><div style=border:none;box-sizing:content-box;height:200px;margin:0;padding:0;width:200px></div></div><script src=/js/clipboard.min.js?1650626698></script><script src=/js/perfect-scrollbar.min.js?1650626698></script><script src=/js/perfect-scrollbar.jquery.min.js?1650626698></script><script src=/js/jquery.sticky.js?1650626698></script><script src=/js/featherlight.min.js?1650626698></script><script src=/js/highlight.pack.js?1650626698></script><script>hljs.initHighlightingOnLoad();</script><script src=/js/modernizr.custom-3.6.0.js?1650626698></script><script src=/js/learn.js?1650626698></script><script src=/js/hugo-learn.js?1650626698></script><script src=/mermaid/mermaid.js?1650626698></script><script>mermaid.initialize({startOnLoad:true});</script><script type=text/javascript>var _paq=window._paq=window._paq||[];_paq.push(["setDocumentTitle",document.domain+"/"+document.title]);_paq.push(["setCookieDomain","*.strolch.li"]);_paq.push(['trackPageView']);_paq.push(['enableLinkTracking']);(function(){var u="https://piwik.eitchnet.ch/";_paq.push(['setTrackerUrl',u+'matomo.php']);_paq.push(['setSiteId','2']);var d=document,g=d.createElement('script'),s=d.getElementsByTagName('script')[0];g.type='text/javascript';g.async=true;g.src=u+'matomo.js';s.parentNode.insertBefore(g,s);})();</script></body></html>
