How to change the delay for a specific message

Question

Hi,
I need to change the delay for an specific message, So how can I consume message by JMSCorrelationID which is enqueued with delay?
I am using Java and Oracle.JMS classes.
This a sample code of the deque method
public BasicAQData dequeue(int insId)
try
     String usr = dbUtil.getCurrentUser();
     AQjmsStreamMessage stream_message = null;
     int id = 0;
     int priority = 0;
     int destino = 0;
     String selector = null;
     String instanceId = String.valueOf(insId);
     BasicAQData dd = new BasicAQData();
     queue = q_sess.getQueue(usr, queue_name);
     selector = "JMSCorrelationID = '"+instanceId+"'";
     receptor = q_sess.createReceiver(queue, selector);
     stream_message = (AQjmsStreamMessage)receptor.receive(sleeptime);
     if (stream_message == null) return null;
     id = stream_message.readInt();
     priority = stream_message.readInt();
     destino = stream_message.readInt();
     stream_message.clearBody();
     dd.setId(id);
     dd.setPriority(priority);
     dd.setDestino(destino);
return dd;
It returns the desired message if that is available; however it returns null if the message was enqueued with delay and isn4t still available.
Thanks in advance.

Hi Glenn,
Messages enqueued with a delay can be dequeued by specifying message id. In your example,
you can dequeue the message with message_id, change the delay and enqueue the message again.
