thanks for your answer!
I used this repository now: https://github.com/droolsjbpm/bpmn2-eclipse-editor
Its the BPMN 2.0 Editor/Designer.
But i have problems finding the Startpoint - I would suggest that I have to start opening a wizard to create a JBPM Project. Isnt it like this ?! Or at which point do you start calling the jbpm-plugin?
