Hi David, Thanks for your anwser.
I allready try including persistence.xml in my webapp. But this doesn't works because I have Service in service.jar with Annotation @PersistenceContext under EntityManager. OpenEJB doesn't find it (because it's defined in the webapp) when it loads service.jar : ERROR - FAIL ... MyService: Missing required persistence.xml for @PersistenceContext ref "entityManager" to unit "jpa-service" Even if this has worked, it is not really what I'm after. Indeed, I will be very interested if "global" persistence units where managed by OpenEJB.
