Its works fine to me to lookup ejb for ejb client on local computer.

When I tried to do same thing on remote computer its does not work.

   public void connect(String url) throws RepositoryException {

//    boolean useJvmIL = System.getProperties().containsKey("jboss.server.name");

    this.url = url;

    if (handler != null) {

      System.out.println("connect login");

      loggedInThreads.login(handler, this, null);

    }

    try {

      initContext();

      /*repository =

        (ZRepository)context.lookup("ejb:000-zert/ZRepositoryBean/remote");*/

      repository =

        (ZRepository)context.lookup("ejb:000-zert/zert-ejb3/ZRepositoryBean!"

      + ZRepository.class.getName() + "?stateful");

      if (repository == null) {

        throw new RepositoryException(I18N.t("Could not lookup repository bean"));

      }

      repository.checkDatabaseVersion();

      repository.getRole();

      repository.setUserName(username);

      queryManager = new QueryManagerImpl(this);

      securityManager = new SecurityManagerImpl(this);

      notificationManager = new NotificationManagerImpl(this, repository);

      openJMSConnections();

   /* } catch (JMSException e) {

      throw new RepositoryException(I18N.t("Failed to setup event queue."), e);

    }*/

      } catch (NamingException e) {

      e.printStackTrace();

      throw new RepositoryException(I18N.t("Failed to lookup interfaces."), e);

    } catch (JMSException e) {

      e.printStackTrace();

      throw new RepositoryException(I18N.t("Failed to lookup interfaces."), e);

    }

  }
