My code goes like this (I have put it in a servlet) ::
code:
     // set the JNDI Properties
          Properties props = new Properties();
     props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
     props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
     props.setProperty("java.naming.provider.url", "localhost:1099");
//      Session mySession= SessionManager.getManager().getSession("comics");
//      ((JNDIConnector)((Session) mySession).getLogin().getConnector()).setLookupType(JNDIConnector.STRING_LOOKUP);
// invoke the session bean object      
     try {
     Context context = new InitialContext(props);
//      DatabaseLogin login = (DatabaseLogin)mySession.getProject().getLogin();
//      javax.sql.DataSource ds = (javax.sql.DataSource) context.lookup("java:system");
//      System.out.println("Data Source "+ds);
//      JNDIConnector connector = new JNDIConnector(ds);
//      login.setConnector(connector);
               src.FirstSession myBeabObj = (src.FirstSession) context.lookup("sample123/FirstSessionBean/remote");
               myBeabObj.sayHello(Name, Age, Dept);
     PrintWriter pwWriter = response.getWriter();
     pwWriter.println("Before calling Persistence");
//      new entityCaller().persistEntity(Name, iAge);
     pwWriter.println("After calling Persistence");
               pwWriter.println("new Deployment"+System.currentTimeMillis());
               pwWriter.println("You submitted Age"+Name);
               pwWriter.println("You submitted Age"+Age);
               pwWriter.println("You submitted Age"+Dept);
//               pwWriter.println("The Bean returned this value"+myBeabObj.sayHello(Name , Age , Dept ));
               System.out.println("Finished Transaction");
          } catch (NamingException e) {
               System.out.println("Exception Reached");
               e.printStackTrace();
          }// end of try catch block

You should probably try a JBoss forum. They're on http://www.jboss.com/index.html?module=bb.
