Persistence Unit and multiple ejb jars in JBOSS 5.1
Hello,
Currently we have a JBOSS 4.3 application with two ejb jars:dbEJB3.jar and messagingEJB3.jar. The first one is responsible for database persistence and has persistence.xml under META-INF. We have the persistence defiend as 'myPU' . The latter jar is responsible purely for jms interaction which does not require PU information. So, no direct reference to any of the DAOs from dbEJB3.jar. It does references other ejb's from dbEJB3.jar which in turn reference DAOs
When we try to upgrade our app to JBOSS 5.1, we see that the application fails to deploy because the messagingEJB3.jar now looks for 'myPU' even though it does not need DAOs. It cannot find the PU information because we have not added the persistence xml in its META-INF.
Why is it even looking for 'myPU' in the first place? Even more surprising is the first line in the error message
16:22:26,687 ERROR [Ejb3Deployment] Exception while processing container metadata for EJB: JPAMyDAO in unit: messagingEJB3.jar
JPAMyDAO is not defined in messagingEJB3.jar but it is defined in dbEJB3.jar instead. There isn't a reference of this DAO in messagingEJB3.jar at all.
Any insights will be much appreciated.
Thanks
