    JNDI Lookup Behing NAT

    maruthi_cse

      Hi All,
      I have a problem in JMS Client lookup. Our present network configuration is

      Client <-->NAT<-->NAT<--->Server.

      When I try to lookup the Server from my Client I am getting an error like connection refused.
      But I can able to connect through browser(i.e. http).

      In the jndi lookup I specified the NAT address. The code can able to communicate the NAT address and able to identify the corresponding local Computer IP Address also.But I am getting connection refused exception.
      What could be the problem?

      My JNDI Lookup Code is
      java.util.Properties properties = new java.util.Properties();

      properties.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");

      properties.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");

      properties.put(Context.PROVIDER_URL,"jnp://203.101.41.32:1099");

      InitialContext iniCtx = new InitialContext(properties);
      Object tmp = iniCtx.lookup("ConnectionFactory");
      TopicConnectionFactory tcf = (TopicConnectionFactory) tmp;


      I am getting the following error if try to run my client

      Exception in thread "main" javax.naming.CommunicationException [Root exception is java.rmi.ConnectException: Connection refused to host: 192.168.27.136 (Internal IP Address)

      Do I need to specify anything else?


      Thanks

          Look in FAQ wikki about JBoss behind firewall. The problem is that RMI-stub, generated by JBoss and sent to client, points to incorrect address. One way is to set some system's props while starting JBoss.
