hey all,
I am facing some problem when I am trying to run a queue browser on JMS
queues. The JMS queue is configured to MQ Queue. When I browse through the
Local JMS queue (queue/A) I am able to browse. On the other hand When the queue
is configured to MQ Queue, and when I browse I have the following error,
| Cannot browse the Queue; - nested throwable: (java.lang.ClassCastException)
| JNDI API lookup failed: org.jboss.mq.SpyJMSException: Cannot browse the
Queue; - nested throwable: (java.lang.ClassCastException)
| org.jboss.mq.SpyJMSException: Cannot browse the Queue; - nested throwable:
(java.lang.ClassCastException)

|
| the Client Code used was as follows,
|
| | //get queue connection factory
| | QueueConnectionFactory qcf = (QueueConnectionFactory) ctx
| | .lookup(cf);
| |
| | //create a connection
| | qc = qcf.createQueueConnection();
| |
| |
| | //create a session.
| | session = qc.createQueueSession(false,
| | Session.AUTO_ACKNOWLEDGE);
| |
| | //get queue
| | Queue q = (Queue) ctx.lookup(queueName);
| | QueueBrowser qb = session.createBrowser(q);
| | Enumeration list = qb.getEnumeration();
| | int count = 0;
| | while(list.hasMoreElements()) {
| | System.out.println("list = " + list.nextElement());
| | count++;
| | }
| |
| Here basically I am interested to know the Queue debth usin JMS.
