How to use BPMN 2.0 ScriptTask with Groovy in JBoss

Note: this blogpost only applies to camunda BPM version < 7.1.0. Starting from camunda BPM 7.2.0 we ship Groovy as part of the pre-packaged distribution. Recently at a customer we added a ScriptTask to a process and wanted to run a Groovy script. Pretty easy with camunda BPM – but in the JBoss environment you have to know how to correctly put Groovy on the classpath – as we correctly use the JSR 223 stuff to recognize existing Scripting Languages. To help others and to remind myself I quickly wanted to blog how to do this. 1.) Add groovy module to your JBoss Download latest groovy-all.jar and copy it to JBOSS_HOME/modules/groovy/main/groovy-all.jar. Create JBOSS_HOME/modules/groovy/main/module.xml with the following content: <?xml version="1.0" encoding="UTF-8"?> <module…

camunda BPM participates in BPMN Roundtrip Demo of OMG

The camunda BPM platform participated in a somewhat extreme BPMN roundtrip demo of the OMG. During that demo, the camunda engine managed to execute a BPMN process model that we pushed through five different modeling tools. Altogether, eight tools participated in the entire roundtrip. Among them where camunda Modeler for editing BPMN in Eclipse, the camunda engine for executing the BPMN process and camunda-bpmn.js for rendering BPMN in JavaScript. In addition, I also did a demo of how to use camunda Cycle for automating BPMN roundtrips.

camunda BPM 7.0-alpha7 released

camunda BPM 7.0.0-alpha7 is out now! The highlights of this new release are: In Cockpit we worked on the visualization of Process Instances: Incidents of a running process instance will be shown in the corresponding rendered process diagram. The former introduced Activity Instance Tree will be visualized as a tree. Now it is possible to select a BPMN element in the rendered process diagram or to select a activity instance within the activity instance tree. If a single BPMN Element is selected, the corresponding activity instances will also be selected in the tree (and vice versa). Variable instances of the process instance/activity instances will be shown in the view. In Cockpit you can switch between the configured process engines (multi-tenancy)….

Introducing an Activity Instance Model to the core Process Engine

(this post was originally part of the 7.0.0-alpha6 release blog post but later extracted into an own post). In 7.0.0-alpha6 we introduced the concept of activity instances and the activity instance tree to the core process engine. This post explains the motivation and gives some insight into the internal implementation. Why do we need an Activity Instance Tree? The activity instance tree contains a node for each activity that is currently active in the process instance. Some activity instances are scopes (such as Embedded Sub processes). Such scope activity instance may have child activity instances: So far so good. But is that not the execution tree provided by the process engine? To some extent yes, but not in all cases. There are…
