    Cannot connect to port 1099

      Hi

      I am using JBoss 3.2.7 and I have an application that need to connect to the server via port 1099. However I am getting the error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out


      A "netstat -ao" shows me that java.exe is listening on localhost:1099 (and other ports)

      However when I try to "telnet 127.0.0.1 1099" or "localhost 1099" all I get is:

      ¼?sr?java.rmi.MarshalledObject|??ù?c?>??I?hashlocBytest?[BobjBytesq~?xp?O?»ur?[B¼??°T??xp#¼?t?http://Brian:8083/q~q~uq~??¼?sr o

      Connection to host lost.

      C:\Documents and Settings\Administrator>

      I can telnet into all other ports on the localhost that java.exe is listening on except 1099. Please help.

      Regards

      Brian

          This looks OK.
          Your JBoss is up and running and will give a RMI connection.
          But telnet does not understand.

          IMO that is not the problem ;-(

            Hi

            Thanks for the quick response wdfink!

            RE: But telnet does not understand.

            Does this mean that I should not be able to telnet port 1099 on the localhost?

            The following is the method I use in the application to get the initialcontext, what changes need to be made to this code so that I can connect to the naming server:

            public static Context getInitialContext() throws NamingException {
            Hashtable<String,String> props = new Hashtable<String,String>();
            props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
            props.put(Context.PROVIDER_URL, "jnp://localhost:1099");
            props.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
            return = new InitialContext(props);
            }

            Regards

              Hi Brian,
              I meant that the answer from JBoss in your telnet is correct.
              JBoss will give a Remotestub, but telnet dont work with it.

              Your connection should work without the URL_PKG_PREFIXES this only restricts the packages.

              regards
