So, I answer my question for selfe again X-(
small instruction how to use selfe created WorkItemHandler in the jbpm-console.
- unzip content of jbpm-installer/jboss-4.2.3.GA/server/default/deploy/jbpm-gwt-console-server.war into jbpm-installer/jboss-4.2.3.GA/server/default/deploy/jbpm-gwt-console-server.war directory
- edit jbpm-installer/jboss-4.2.3.GA/server/default/deploy/jbpm-gwt-console-server.war/WEB-INF/classes/META-INF/CustomWorkItemHandlers.conf file
[
"Log": new org.jbpm.process.instance.impl.demo.SystemOutWorkItemHandler(),
"myhandler": new de.processes.jbpm5.MyNewHandler(),
]
- copy your .jar library containing the 'de.processes.jbpm5.MyNewHandler()' class file into jbpm-installer/jboss-4.2.3.GA/server/default/deploy/jbpm-gwt-console-server.war/WEB-INF/lib/
Now you can create new bpmn process file containing:
<task id="_4" name="Task using my Handler" tns:taskName="myhandler" >
(...)
</task>
I hope somebody find this hint usefull. :D
