      Prefix the "unitName" in the @PersistenceContext injection with random 3 letters.

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

      import org.jboss.annotation.ejb.RemoteBinding;
      import org.myapp.ejb.AppManager;

      @Stateless
      @Remote (

      {AppManager.class}

      )
      @RemoteBinding (jndiBinding = "AppManagerBean")
      public class AppManagerBean implements AppManager {

      @PersistenceContext (unitName="myapp_ejb3.jar#EJB3Persistence")
      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
       
        — META-INF
         
          — application.xml
         
          — jboss-app.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

      When this application is deployed in 4.2.2 the deployment fails with an exception. Part of the exception is pasted below. The relevant log files (ConsoleLog_Fail.txt and serverLog_fail.txt in the logs.zip file) are attached.

      If i change the PersistenceContext injection, in the bean, to prefix 3 random letters to the unitName as follows:

      @PersistenceContext (unitName="XXXmyapp_ejb3.jar#EJB3Persistence")
      private EntityManager em;

      and deploy the application, then everything works fine (have also attached the successful logs ConsoleLogs_Success.txt and serverLogs_Success.txt in the logs.zip file).
