yes, it is a Queue. I am a little suprised at this problem, although I have
never done a Queue before usually always dealing with topics.
I need to distribute a process. a queue with multiple consumers seemed the
perfect answer, because each task passed along could get grabbed by exactly one
consumer.
| <mbean code="org.jboss.mq.server.jmx.Queue"
| name="jboss.mq.destination:service=Queue,name=uncategorizedpages">
| <depends
optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends>
| </mbean>
|
The code uses Queue in the usual way:
| Context ctx = new InitialContext(config);
| QueueConnectionFactory queueFactory = (QueueConnectionFactory)
ctx.lookup("ConnectionFactory");
| Destination queueDestination = (Destination)
ctx.lookup(unitQueueName);
|
| QueueConnection queueConnection = (QueueConnection)
queueFactory.createConnection(unitQueueUser, unitPagesQueuePass);
| Session queueSession =
queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
|
| List<UnitVO> batch = loadBatch(0);
|
|
| // for each page in the batch
| for (UnitVO unit : batch)
| {
| MessageProducer producer =
queueSession.createProducer(queueDestination);
| producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
| ObjectMessage msg = queueSession.createObjectMessage(page);
| producer.send(msg);
| producer.close();
|
| }
| queueSession.close();
| queueConnection.close();
|
| Context ctx = new InitialContext(this.config);
| QueueConnectionFactory queueConnnectionFactory =
(QueueConnectionFactory) ctx.lookup(connectionFactoryJNDIName);
| QueueConnection queueConnection =
queueConnnectionFactory.createQueueConnection(unitQueueUser, unitQueuePass);
| QueueSession unitSession =
| queueConnection.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
| Queue unitQueue =
| (Queue) ctx.lookup(unitQueueName);
| QueueReceiver receiver =
| unitSession.createReceiver(unitQueue);
| queueConnection.start();
|
|
| // until we are told to stop
| while (!shutdown)
| {
| Message msg = receiver.receive(1000);
|
| if (msg != null && msg instanceof ObjectMessage)
| {
| UnitVO page = (UnitVO) ((ObjectMessage)
msg).getObject();
| System.out.println(unit.getId());
| }
| else {
| shutdown=true;
| }
| }
