    JBoss issue? 2 EJBs implemented the same, but only one can b

    Phil Clark Newbie

      Is the issue with the ApplicationServer?

      I have two EJB's, MemberBean and PersonBean, implemented the same way. However, jndi lookup is successful for one (MemberBean), but not the other (PersonBean - javax.naming.NameNotFoundException on the second lookup). See below for the detail, I don't get this one:

      From the log file you can see that both beans are bound succesfully

      APPSERVER LOG FILE

      ##However the PersonBean fails the context lookup ##

      Both Beans are found in the jndi view

      PersonBean lookup:

       private PersonBeanLocal getLocalSession()
       {
       PersonBeanLocal local = null;
      
       try
       {
       logger.debug("ENTERED>>>>>>>>>>>>>>>>>>>>>");
      
       Context ctx = new InitialContext();
       Object ref = ctx.lookup("java:comp/env/PersonBeanLocalHome");
      
       logger.debug("GOT PERSON EJB");
       logger.debug("Object ::: " + ref.getClass().getName());
      
       PersonBeanLocalHome home = (PersonBeanLocalHome)ref;
       local = home.create();
       }
       catch(Exception e)
       {
       logger.error("" + e.toString());
       }
       return local;
       }
      


      MemberBean lookup:

       private MemberBeanLocal getLocalSession()
       {
       MemberBeanLocal local = null;
      
       try
       {
       Context ctx = new InitialContext();
       Object ref = ctx.lookup("java:comp/env/MemberBeanLocalHome");
      
       logger.debug("GOT MEMBER EJB");
       logger.debug("Object ::: " + ref.getClass().getName());
      
       MemberBeanLocalHome home = (MemberBeanLocalHome)ref;
       local = home.create();
       }
       catch(Exception e)
       {
       logger.error("" + e.toString());
       }
       return local;
       }
