[jboss-user] [EJB/JBoss] - How do I use the same JPA entities in multiple applications?

JBoss 4.2.2 I have some JPA entities packaged in User-entity.jar with a persistence context named 'UserPU'. I include this User-entity.jar in an ejb.jar and deploy it. This works great and I can CRUD entities. Now I want to include the User-entity.jar in a separate application (ear or ejb-jar) and when deployed I get the following WARNING: 13:29:37,778 WARN [ServiceController] Problem starting service jboss.j2ee:module=User-entity-0.1-test.jar,uid=1243449447,service=EJB3 | java.lang.RuntimeException: javax.management.InstanceAlreadyExistsException: persistence.units:unitName=UserPU already registered. | Is it possible to reuse JPA entities in this way? Is it recommended? thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4165178#...
