Message Transformation with JMS AQ
}
publisher = jms_session.createPublisher(topic);
/* set the transformation in the publisher */

Receiving Messages from a Destination Using a Transformation
A transformation can be applied when receiving a message from a queue or topic.
The transformation will be applied to the message before returning it to JMS
application.
The transformation can be specified using setTransformation( ) interface of the
AQjmsQueueReceiver, AQjmsTopicSubscriber and
AQjmsTopicReceiver.
Example Code
Lets say the Western Shipping application retrieves messages from the OE_
bookedorders_topic. It specifies the transformation ’OE2WS’ to retrieve the message
as the WS_order ADT.
Lets say that the WSOrder Java class has been generated by Jpublisher to map to the
Oracle Object WS.WS_order
public AQjmsAdtMessage retrieve_booked_orders(TopicSession jms_session)
AQjmsTopicReceiver receiver;
Topic topic;
Message msg = null;
try
{
/* get a handle to the OE_bookedorders_topic */
topic = ((AQjmsSession)jms_session).getTopic("OE",
"OE_bookedorders_topic");
/* Create a receiver for WShip */
