    @PersistenceContext injection from a different jar fails

    John smith Newbie

      Hello,

      I have a sample application with an EJB3 SLSB which is being injected with a PersistenceContext which is configured in a different jar file as follows :

      package org.myapp.ejb.impl;

      import javax.ejb.Local;
      import javax.ejb.Stateless;
      import javax.persistence.EntityManager;
      import javax.persistence.PersistenceContext;

      import org.myapp.ejb.AppManager;

      @Stateless
      @Local ({AppManager.class})
      public class AppManagerBean implements AppManager {

      @PersistenceContext (unitName="myapp_ejb3.jar#MyPU")
      private EntityManager em;

      public String getVersion() {
      System.out.println("EM is " + em);
      return "1.0";
      }


      }


      The application is deployed as an EAR file in the following structure:

      EJB3Persistence.ear
      |
      |--- META-INF
      | |
      | |----application.xml
      | |

      |--- myapp_ejb3.jar (contains the persistence.xml)
      | |
      | |--- META-INF
      | | |
      | | |--- persistence.xml
      |
      |
      |
      |--- another_ejb3.jar (contains the SLSB)
      | |
      | |
      | |--- META-INF
      | |
      | |--- org.myapp.ejb.impl.AppManagerBean


      Note that this application is deployed fine in JBoss-5.0.0.Beta4,

      but with 5.0.0.CR2 the deployment fails.

      Part of the exception is pasted below:

      I found the same bug here : http://www.jboss.com/index.html?module=bb&op=viewtopic&t=146052

      I applied the solution he suggested : jboss-JPA-deployers-1.0.0.Beta4, but this do not solve the problem!

      if someone has an idea?

      Thank's a lot.
