    EJB Bound problem.  Help!

    nikhilkumar Newbie

      I have been trying to figure out how to deal with an ejb reference:
      JBOSS V3.2

      It is my undertanding that:
      1. The ejb-jar.xml needs to have
      ejb-name defined. In my case this is
      <ejb-name>HelloWorld</ejb-name>
      2. The jboss.xml (and I am not clear if this is necessary, though i want to support clustering in the future and so cannot guarantee that everything will be on the same server).


      <ejb-name>HelloWorld</ejb-name>
      <jndi-name>/tsm/HelloWorld</jndi-name>

      <method-attributes>
      </method-attributes>


      3. The web.xml entry
      <ejb-ref>
      <ejb-ref-name>ejb/HelloWorld</ejb-ref-name>
      <ejb-ref-type>Session</ejb-ref-type>
      com.aptsi.applications.tsm.ejb.HelloWorldHome
      com.aptsi.applications.tsm.ejb.HelloWorld
      <ejb-link>HelloWorld</ejb-link>
      </ejb-ref

      Note that the web-uri setup in application.xml is:

      <web-uri>tsm.war</web-uri>
      <context-root>/tsm/web-app</context-root>
      and that has working. Also, I do not see any deployment of the ejb.jar, unlike the war which I see on the console. The console also indicates that the ear has deployed.

      4.The jboss-web.xml entry

      ><ejb-ref>
      <ejb-ref-name>ejb/HelloWorld</ejb-ref-name>
      <jndi-name>/tsm/HelloWorld</jndi-name>
      </ejb-ref>

      5. The code:

      try
      {
      System.out.println("Testing ejb access - before context lookup");
      Context ctx = new InitialContext();
      ctx = (Context)ctx.lookup("java:comp/env/ejb");
      Object o = ctx.lookup("HelloWorld");
      System.out.println("Testing ejb access - after context lookup");
      HelloWorldHome home = (HelloWorldHome)
      PortableRemoteObject.narrow(o, HelloWorldHome.class);

      System.out.println("Testing ejb access - jndi op complete");
      // get the bean remote instance
      //
      try
      {
      System.out.println("Testing ejb access - before create");
      HelloWorld h = home.create();
      System.out.println("EJB created, Need to test ejb access");
      System.out.println(h.helloWorld());
      }
      catch (javax.ejb.CreateException e)
      {
      System.out.println(e.getMessage());
      }
      catch (java.rmi.RemoteException e)
      {
      System.out.println(e.getMessage());
      }
      }
      catch (javax.naming.NamingException e)
      {
      e.printStackTrace() ;
      }


      The stack trace is:
