Re: persistence.xml in a Jar in Tomcat Common classloader (ERROR : PersistenceUnit already deployed)
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.

Well I'll be interested in such feature also :)
Re: persistence.xml in a Jar in Tomcat Common classloader (ERROR : PersistenceUnit already deployed)
Hi Maxime, It should be possible to put the service.jar in the Tomcat lib/ directory without a persistence.xml in it and then include that persistence xml in your webapp. You should be able to include a file> element in the unit declaration that points to the C:/tomcat6/ lib/service.jar so all the entities will be discovered without having to explicitly list them via the element. You'd have to include the same persistence.xml in each webapp that wanted to reuse the classes in service.jar. Not entirely sure though if that's really what you're after. We don't currently have any support for "global" persistence units. Meaning say a persistence unit declared outside of an ear at server level and available to all ears/apps deployed. It might be something we could add if that's really what you're after. -David On Oct 16, 2008, at 12:25 AM, Maxime Thieu wrote: Hello everybody, I am developping ejb-jar module (let's call it service.jar) which contains EJB, Entity, Service and persistence.xml (in META-INF).

Hello everybody, I am developping ejb-jar module (let's call it service.jar) which contains EJB, Entity, Service and persistence.xml (in META-INF).
