Thanks Esteban, I already copied the ServiceTaskHandler class and invoked my own java class with it, similar to the HelloProcess Example. So this works.



The interface was a bit hidden, but already defined in the example above:



  <bpmn2:interface id="_2_ServiceInterface" name="org.jbpm.examples.junit.HelloService">
    <bpmn2:operation id="_2_ServiceOperation" name="hello"/>
  </bpmn2:interface>



I am successfully invoking a webservice with it and transfering json data in my process. So finally a feeling of success  :)

I never really had an issue with opening the xml from the BPMN Eclipse 2.0 Editor in Oryx or vice versa. Oryx and the Eclipse BPMN 2.0 Editor work perfectly together and are in my opinion also compliant with the BPMN 2.0 spec. My problem is solely the execution of an Oryx generated xml code in eclipse with a processTest.java file.



I wrote the whole xml again by hand and now it works (The example below is a bit more advance at this stage already). I think I will go on coding it by hand for now. 

However, it would be nice if the example (working in oryx and eclipse editor plugin) that I posted above would be executable. It is the same semantic structure as the xml below. So it must be a syntax issue.
