    Multiple persistence-units causes deployment failure

    Dan Donahue Newbie

      I have two persistence units defined in my persistence.xml file (located in META-INF of my project). When I deploy the project .ear file in JBoss 4.2.2 I  get the following error:

       

      [ServiceController] Problem starting service jboss.j2ee:service=EJB3,module=serverapp.jar

      Here is the persistence.xml file:

       

      <?xml version="1.0" encoding="UTF-8"?>
      <persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">

       

      <persistence-unit name="prvsnr/persistence" transaction-type="JTA">

              <jta-data-source>java:/prvsnr/datasource</jta-data-source>
         </persistence-unit>

       

          <persistence-unit name="reportControl/persistence" transaction-type="JTA">
              <jta-data-source>java:comp/env/reportControl/reportsdatasource</jta-data-source>
         </persistence-unit>

       

      </persistence>

       

      And, in the entity facades, I annotate accordingly:

       

      @PersistenceContext(unitName = "reportControl/persistence", type=PersistenceContextType.TRANSACTION)
          protected EntityManager entityManager;

       

      The data source files are all seemingly correct (*-ds.xml) as they connect to the databases appropriately.

       

      It seems that we only have problem with those entities that use the SECOND persistence unit define. Those that refer to the first unit behave okay. (Verified by removing the 2nd p-unit definition from the peristence.xml file, recompiling and redeploying without error.)

       

      I simply can't find an reason why this is happening.
