Hi Friends,

I'm trying to test a very simple process with one sevice task, and I want to manage Java Delegate class as a spring managed bean. I've followed all the steps described in Activiti User Guide, but still I'm getting "Bean Not Found" error. Highly appriciate, if anybody can help me figure out my missing point. I have highlighted the log with my findings.

The process engine should be a SpringProcessEngineConfiguration. I don't see (except where referenced in osgi:… id="processEngine") where the process engine is configured and what its class is
