    Failed to find persistence unit

      Hi

      I'm currently migrating a working JBoss 4.0.5.GA EAR to 5.0.0.GA. The ear is structured as this:

      EAR
 |- Servlet WAR
 |- Utility JAR
 |- MDB (jms)
 |- EJB_3 (stateless/no entities, no persistence)
 |- EJB_1 (stateless/entities)
 |-1PU
 |- EJB_2 (stateless/entities)
 |-2PU


      Each of the EJB3 with entities have their own persistence.xml

      The EJB_3 with no entities, uses the EJB_1 and EJB_2 by Local interfaces.

      When I deploy on JBoss 5, a "failed to resolve persistence unit 1PU" error is thrown. No for 2PU, only for 1PU.

      So, I copy the 1PU persistence.xml file into the troublesome bean EJB_3 and deployments goes fine. But now, I get "Cannot open connection" errors.

      Each of this beans are independent of each other.

      The workflow is something like 
      x-->servlet-->jms_queue-->MDB-->EJB_3-->EJB_1

      Any help? Thanks
