    Jboos Lookup

    Sattler Benedikt Newbie

      Hello!

      I have a problem. I have developed a Bean and deployed it with RedHatDeveloper Studio. If I look at the managed Bean JNDIView, I am able to see the Bean under the global JNDI Section. I have developed a client programm that accesses the bean, but I get allways an exception if I try to access the bean. What can I do?

      There is the client source code:
      Properties jndiProps = new Properties();
      jndiProps.setProperty(Context.INITIAL_CONTEXT_FACTORY,
      "org.jnp.interfaces.NamingContextFactory");
      jndiProps.setProperty(Context.URL_PKG_PREFIXES,
      "org.jboss.naming:org.jnp.interface");
      jndiProps.setProperty(Context.PROVIDER_URL, "jnp://jboss-server:1099");
      InitialContext txt = new InitialContext(jndiProps);
      System.out.println(txt);
      System.out.println(txt.lookup("SubBean/local"));

      And the Name of the bean in the global JNDI is:
      SubBean *
      -local
      best regards

          Which version of JBoss are you using? Is your client a standalone java class? Post the entire exception stacktrace and also the exact contents of the JNDI tree as you see from the jmx-console.

            And the Client is a standalone client.

            Thanks

              Thanks for the help, but I have found the problem.
