Scheduled delivery of individual messages

Question

I've ready through the forum and have found a way to deliver a JMS message at some point in time by setting the producer:
          ((weblogic.jms.extensions.WLMessageProducer) qsender).setTimeToDeliver(cal.getTime().getTime());
          However, I do NOT want to affect every message sent by the producer, as this method seems to do.
          I want to be able to set a time of delivery for individual messages. Is this the purpose of the DeliveryTime header? How do I set this properly; will this work:
          objectMessage.setLongProperty("DeliveryTime", deliverDate.getTime())
          thanks!

This is how I've solved the problem of setting a delivery time for individual messages. My unit tests confirm it works as expected, it just feels like a hack.
          public void publish(Message message, Date absDeliveryTime) {
          // reset the timeToDeliver for the publisher
          // as the previous call may have set this
          ((WLMessageProducer) publisher).setTimeToDeliver(-1);
          if (absDeliveryTime != null) {
          Date timeNow = new Date();
          ((WLMessageProducer) publisher).setTimeToDeliver(
          absDeliveryTime - timeNow.getTime());
          }
