    UnknownHostException when connecting to remote topic on jboss 7.2.0.Final

    Somefname1 Somelname1 Newbie

      I'm trying to connect to topic on jboss 7.2.0.Final which is running on remote computer (connection works localy).

       

      Client code:

      //JNDI props
      Properties params = new Properties();
      params.setProperty(
                "jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT",
                "false");
      params.setProperty(Context.URL_PKG_PREFIXES,
                "org.jboss.ejb.client.naming");
      params.setProperty(Context.INITIAL_CONTEXT_FACTORY,
                "org.jboss.naming.remote.client.InitialContextFactory");
      params.setProperty(Context.PROVIDER_URL, "remote://192.168.10.222:4447");
      params.setProperty(Context.SECURITY_PRINCIPAL, "user");
      params.setProperty(Context.SECURITY_CREDENTIALS, "password");
      
      //JNDI lookup and connect
      Context context = new InitialContext(params);
      ConnectionFactory cf = (ConnectionFactory) context.lookup("jms/RemoteConnectionFactory");
      Destination destination = (Destination) context.lookup("jms/cms/topic/ttt");
      Connection connection = cf.createConnection(user, password);
      Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
      connection.start();
      
      //Send message
      MessageConsumer subscriber = session.createConsumer(destination);
      MessageProducer publisher = session.createProducer(destination);
      TextMessage message = session.createTextMessage("Hello world message.");          
      publisher.send(message);
      subscriber.setMessageListener(new MessageListener() {     
           public void onMessage(Message msg) {
                TextMessage tm = (TextMessage) msg;
                try {
                     String message = tm.getText();
                     System.out.println("Got message: " + message);
                     
                } catch (Exception e) {
                     e.printStackTrace();
                     
                }
           }
      });
      

       

      standalone-full.xml contains:

      <jms-topic name="ttt">

          <entry name="topic/ttt"/>

          <entry name="java:jboss/exported/jms/cms/topic/ttt"/>

      </jms-topic>

      server is started like this:

      ./bin/standalone.sh -b 192.168.10.222 -c standalone-full.xml
      

       

      All this gives me exception:

      IMHO, netty is trying to connect using resolved hostname, not ip. I think, that such behavior is incorrect.

       

      Also, I saw bug [AS7-4594] do not resolve socket-bindings used by messaging - JBoss Issue Tracker - but it seems resolved.
