QueueBrowser doesn't enumerate all messages

Question

Hi there,
I've the problem that, using a QueueBrowser, I don't get all messages from a Queue but only the first (say, out of five), using a MessageConsumer, I get all five messages.
This problem occurs, when I use (our own) administrative tool to peek at a queue with QueueBrowser, take the message and "copy" it to a backup-queue by simply sending it there via a MessageProducer. Once this "backup" queue has more than a single message in it, abovementioned problem occurs - is this supposed to work (simply re-sending a peeked message somewhere)?
(Of course, this question is about the development of our own admin tool, which doesn't work for some reason in this case, not its usage or such).
kind regards,
Messi

Hi,
Under OpenMQ 4.1 I had success using a QueueBrowser . I am also using the Spring Framework 2.5.5.
Please post if you have any questions about the code snippet...
Here is a code snippet that works for me:
        JmsQueueBrowser browser = new JmsQueueBrowser();
        browser.setQueueName("testQueue");
        JmsTemplate myJmsTemplate = browser.getJmsTemplate();
        FileSystemXmlApplicationContext myCtx = browser.getCtx();
        final Queue queue = (Queue) myCtx.getBean(browser.getQueueName());
         * Browse thru the Queue specified
        Integer count = (Integer) myJmsTemplate.execute(new SessionCallback()
            public Object doInJms(Session session) throws JMSException
                int count = 0;
                QueueBrowser browser = session.createBrowser(queue);
                Enumeration<Message> messages = browser.getEnumeration();
                Message myMessage;
                while (messages.hasMoreElements())
                    count++;
                    myMessage = messages.nextElement();
                    System.out.println(new Date() + "\nQueue:" + queue.getQueueName() + "\nMessage[" + count + "]:" + myMessage + "\n");
                return new Integer(count);
        });Here is output from the code supplied:
