--------------------------------------------------------------
I would like after do something consume/delete/take out the message from queue, but I can't ....
I have  4 messages on queue and I want consume just one

QueueConnectionFactory factory = (QueueConnectionFactory) getInitialContext().lookup("/ConnectionFactory");//java:/ConnectionFactory
            Queue queue = (Queue) getInitialContext().lookup("queue/MyQueue");
            connection  = factory.createQueueConnection();
            session = connection.createQueueSession(false, QueueSession.AUTO_ACKNOWLEDGE);
*QueueBrowser* queueBrowser = session.createBrowser(queue);

            Enumeration<ObjectMessage> messages = queueBrowser.getEnumeration();
            while (messages.hasMoreElements()) {
                ObjectMessage objectMessage = (ObjectMessage) messages.nextElement();
                Person p = (Person) objectMessage.getObject();
                System.err.println(p.getId());                
                //do something....
                //* after do something take out the message from queue
            }

* I tried code below, but i got error
QueueReceiver receiver = session.createReceiver(queue, "JMSMessageID="+objectMessage.getJMSMessageID());
MessageConsumer consumer = session.createConsumer(queue, "JMSMessageID="+objectMessage.getJMSMessageID());
