[jboss-user] [EJB 3.0] - Re: Single persistence.xml file with multiple EJB jars

Can you give us a bit more specific example of your case? You mentioned you have 2 ejb jars msp1_ejb.jar and msp2_ejb.jar which are trying to use a the same persistence unit. If i understand your scenario right, you could have something like this: | msp.ear | | | |--- META-INF | | | | | |-- application.xml | | | | | |--- mypersistence.jar | | | | | |--- META-INF | | | | | | | |--- persistence.xml | | | | | |--- <entities> | | | | | |--- msp1_ejb.jar | | | |--- msp2_ejb.jar | | And in the EJBs in the msp1_ejb.jar and msp2_ejb.jar, you could inject the persistence context as follows: | @PersistenceContext (unitName="mypersistence.jar#msp-par") | private EntityManager manager; Let us know, if i did not understand your scenario right.
