[jbpm-users] EJB Business Intelligence with KnowledgeBases / Sessions

Dear Community! I would like to ask you about the new jBPM 5 API. I would like to manage jBPM sessions and tasks in my J2EE application so I need to create a "connection" between my app and the jBPM runtime. I do know that jBPM console was created for this purpose, but we would like to sharpen HumanTask part. I would like connect / couple my app and the runtime only by middleware API which would not change (hopefully) by the time, and avoid database manipulating. So my question: Is there any way to "Inject" KnowledgeBases / Sessions into my EJB or get them anyhow? Thank You very much! Norbert Korodi
