HornetQ JMSException: Failed to create session factory

问题:

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

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.
