    obtaining remote ejb ref via localhost lookup?

    Sharath Komarla Newbie

      Hi Guys,

      I have an issue with looking up a remote ejb via JNDI lookup when I use localhost instead of the actual machine name. I know that in a real environment, one would never use localhost, but we have a large team of developers that are used to just using localhost that would be somewhat annoyed if I broke this on them.

       m_providerUrl = "socket://localhost:3873";
      
       .... <snip>
      
       Properties properties = new Properties();
      
       properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.JBossRemotingContextFactory");
       properties.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
       properties.setProperty(Context.PROVIDER_URL, m_providerUrl);
      


      If I replace the above provider url like below, the remote ejb lookup works.

       m_providerUrl = "socket://skomarla:3873";
      


      The exception I get is
      org.jboss.remoting.CannotConnectException: Can not get connection to server. Problem establishing socket connection for InvokerLocator [socket://localhost:3873/]

      netstat -an | grep 3873 reports only listening on the actual ip and not 0.0.0.0:3873.
       Proto Local Address Foreign Address State
       TCP 10.20.20.37:3873 0.0.0.0:0 LISTENING
      


      Is this just a matter configuring JBoss remoting? If so, what would that configuration change be such that the appserver listens on both localhost and actual machine's ip?

      Thanks for the help
