    Cannot connect to HornetQ via Remote call when wildfly 8.1.0 install is behind a NAT

    juice0123 Newbie

      Cannot connect to jms via Remote call when wildfly 8.1.0 installs are on a different subnet. I currently have this working on the same subnet. I can connect when on the same subnet, but when on a different subnet, it fails to create the connection. The following is the method i use that works on the same subnet and breaks on a different subnet.

                

                      final Properties env = new Properties();

                      env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

                      env.put(Context.PROVIDER_URL, System.getProperty(Context.PROVIDER_URL, "http-remoting://" + ip + ":" + port));

                      env.put(Context.SECURITY_PRINCIPAL, System.getProperty("username", User));

                      env.put(Context.SECURITY_CREDENTIALS, System.getProperty("password", Password));

                      initialContext = new InitialContext(env);

       

                     //The next two lines work

                      ConnectionFactory cf = (ConnectionFactory) initialContext.lookup("jms/RemoteConnectionFactory");

                      Destination destination = (Destination) initialContext.lookup("java:/jms/queue/" + queueName);

       

                    //fails here, cannot create the connection

                      Connection connection = cf.createConnection(User, Password);

       

                      Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

                      MessageProducer producer = session.createProducer(destination);

                      connection.start();

       

      I had this working on jboss 5.1.0 sending to remote queue messages to the queue on a jboss7.1.2 install, but only with the host file on the client machine changed to reflect the host name of the machine to its ip. I have ported both servers the wildfly 8.1.0 and I can't get it working across different subnets. I keep getting the following error


      javax.jms.JMSException: Failed to create session factory

      Caused by: HornetQNotConnectedException[errorType=NOT_CONNECTED message=HQ119007: Cannot connect to server(s). Tried with all available servers.]

        at org.hornetq.core.client.impl.ServerLocatorImpl.createSessionFactory(ServerLocatorImpl.java:905) [jboss-client-8.1.jar:8.1.0.Final]

        at org.hornetq.jms.client.HornetQConnectionFactory.createConnectionInternal(HornetQConnectionFactory.java:669) [jboss-client-8.1.jar:8.1.0.Final]


      Any Ideas?

          Can you paste the configuration of your "jms/RemoteConnectionFactory"?

            I think i might have discovered the problem. My wildfly server is behind a NAT, so the ip address that i bind wildfly to, is not the same address that the client is sending the data to teh queue to. For instance. X is the client and Y is the server. X sends to address 1.1.1.1 ..... through NAT it sends the data to 2.2.2.2  on server Y. I think this may be the issue.

              Hi Juice!  I'm having the same problem and wondering how you were able to resolve it?  I'm digging around through other posts but havent found a more recent solution!  Any help would be appreciated!

                Please create a new thread with a full explanation of your use-case and problem and I'll try to help.  If the problem is with NAT then it should be pretty simple to resolve.

                  Here you go Justin!
                  JMS Message Queue, NAT'ed IP - change ?advertised? address

                  I'm also trying the JBoss 7 fixes but none seem to be working, e.g. the link at the bottom!

                   

                  Thank you!
