    Nebulous Null Pointer

    Mike Duffy Novice

      I am getting a null pointer exception at start up (using the latest EJB 3.0 Preview Release). I know that it means there is something wrong in myejb.ejb3; however, I get this very long stack trace that has all kinds of references to JBoss and Hibernate, but no reference to the cause of the problem in myejb.ejb3.

      Does anyone have any guidance on ow to debug this?

      Here are the first few lines of the stack trace.

      01:00:18,045 ERROR [Ejb3Module] Starting failed
