JMS queue messages viewing without removing them from the queue

I want to view ALL messages (message-driven POJOs) of a queue without removing them from the queue. Is there a way to accomplish that?

I found out that with "sessionAcknowledgeMode", I can view one single message before acknowledging and removing it from a queue. But thats not what I want. I want a list of all the message without actually removing them.

THX!

Have a look at JmsTemplate.browse* methods.

Thanks for the hint...it really helped me out. In the following I'm posting my working source code for future readers.

Code:

---

jmstemplate.browse("requestQueue", new BrowserCallback<RepositoryUpdateRequest>() {
        @Override
        public RepositoryUpdateRequest doInJms(Session session, QueueBrowser browser) throws JMSException {
                System.out.println("Whats in the query?");
                int i = 1;

                Enumeration e = browser.getEnumeration();

                if (e instanceof ActiveMQQueueBrowser) {
                        ActiveMQQueueBrowser activemqbrowser = (ActiveMQQueueBrowser) e;

                        while (activemqbrowser.hasMoreElements()) {
                                Object o = activemqbrowser.nextElement();
                               
                                if (o instanceof ActiveMQObjectMessage) {
                                        ActiveMQObjectMessage amq_message = (ActiveMQObjectMessage) o;
                                        Object obj = amq_message.getObject();

                                        if (obj instanceof RepositoryUpdateRequest) {
                                                RepositoryUpdateRequest request = (RepositoryUpdateRequest) obj;
                                                System.out.println(i + ": " + request.getTEST());
                                        } else {
                                                System.out.println(i + ": " + "not a RepositoryUpdateRequest");
                                        }
                                        i++;
                                }
                        }
                }

                return null;
        }

});

You don't need cast to Active MQ classes.
Message in your case can be casted to javax.jms.ObjectMessage.
