HornetQ JMSException: Failed to create session factory

Question

I'm trying to Directly instantiating JMS Resources without using JNDI to a REMOTE HORNETQ.

I am running my test code in Eclipse IDE. Setup my classpath to use the HornetQ 2.2.5 libraries.

The target HornetQ is version 2.1.2.Final, I figured they should be backwards compatible, maybe im wrong?

Okay, so I have read the online documentation and followed the examples on connecting to a remote JMS server without using JNDI. I keep on getting the following exception. Im not sure what Im missing but I believe I have everything setup correctly. Could someone please point out what Im missing here? Thanks in advance.

JMSException: Failed to create session factory

The connector on hornetq-configuration.xml is:

  <connector name="netty">
     <factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>
          <param key="host"  value="${10.100.111.222}"/>
          <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
  </connector>

The acceptor is:

  <acceptor name="netty">
     <factory-class>org.hornetq.core.remoting.impl.netty.NettyAcceptorFactory</factory-class>
      <param key="host"  value="${10.100.111.222}"/>
     <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
  </acceptor>

My Test code is: Connection connection = null;

   try
   {
    Queue queue = HornetQJMSClient.createQueue("TESTQ");

    Map<String, Object> connectionParams = new HashMap<String, Object>();
    connectionParams.put(TransportConstants.PORT_PROP_NAME, 5445);
    connectionParams.put(TransportConstants.HOST_PROP_NAME, "10.100.111.222");        

    TransportConfiguration transportConfiguration = new TransportConfiguration(NettyConnectorFactory.class.getName(),
                                                                               connectionParams);
    ConnectionFactory factory = (ConnectionFactory) HornetQJMSClient.createConnectionFactoryWithoutHA(JMSFactoryType.CF, transportConfiguration);
    System.out.println("debug: " + factory.getClass());

    connection = factory.createConnection();

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

    MessageProducer producer = session.createProducer(queue);

    TextMessage message = session.createTextMessage("This is a test message");
    System.out.println("Sent message: " + message.getText());

    producer.send(message);

   }
      finally
      {
         if (connection != null)
         {
            try {
                connection.close();
            } catch (JMSException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
         }
      }

I get the following Exception

Answer 1

Regarding compatibility: We didn't have client compatibility until 2.2.5+. If you try client on 2.2.2 and server at 2.2.5, you will probably get a version mismatch exception.

We are aiming to always be compatible from 2.2.5+

And you have a typo in your config:

  <connector name="netty">
     <factory-class>org.hornetq.core.remoting.impl.netty.NettyConnectorFactory</factory-class>
          <param key="host"  value="10.100.111.222"/>
          <param key="port"  value="${hornetq.remoting.netty.port:5445}"/>
  </connector>

We use a syntax for properties and default values. You could for instance define a variable MY_IP and use it as:

"${MY_IP:10.100.111.222}"

If MY_IP is null, you would get 10.100.111.222

But "${10.100.111.222}" doesn't mean anything.
