Hi Ali, thanks for your pointers, they were very helpful!

So i thought of subclassing TIJavaLauncherDelegate get somehow to the launched process to register my IProcessListener. The Listener itself triggers something of my code to query the emf model to go to step 5 and open a corresponding with my callgraphView. My problem is: access to all the relevant classes named above is prohibited, so no subclassing is possible. I am sure i overlooked a special factory which helps me doing the job, right?
