How to use Java JMS with MQseries

Question

I am trying to develop a JMS standalone application to read and write to a Queue on MQSeries. My boss asked me to use pure java JMS (not ibm.m

If you don't mind writing WMQ-specific code then you can do

MQConnectionFactory cf = new MQConnectionFactory();
cf.setHostName(HOSTNAME);
cf.setPort(PORT);
cf.setChannel(CHANNEL);
cf.setQueueManager(QMNAME);
cf.setTransportType(WMQConstants.WMQ_CM_CLIENT);

then usual JMS resources

Connection c = cf.createConnection();
Session s = c.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue q = s.createQueue("myQueue"); // replace with real queue name
MessageProducer p = s.createProducer(q);

and finally create and send a message

Message m = s.createTextMessage("Hello, World!);
p.send(m);

(i've typed that in off the top of my head so can't rule out a typo, but it's fundamentally correct). If you're really supposed to be using 'pure JMS' - i.e. with no provider-specific objects - then you need to bind a MQConnectionFactory object in JNDI (take a look at the JMSAdmin tool, it's in the docs) then look it up from your application, i.e.

InitialContext ic = new InitialContext(); // or as appropraite
ConnectionFactory cf = (ConnectionFactory)ic.lookup("myMQfactory"); // replace with JNDI name
