Advanced Queuing - Oracle

General Features of JMS
Object Message
An ObjectMessage is used to send a message that contains a serializable Java object.
It inherits from Message and adds a body containing a single Java reference. Only
serializable Java objects can be used. If a collection of Java objects must be sent, one
of the collection classes provided in JDK 1.2 can be used. The objects can be read or
written using the methods getObject() and setObject(...).To use Object
Messages, create the queue table with the SYS.AQ$_JMS_OBJECT_MESSAGE or
AQ$_JMS_MESSAGE payload types.
Example Code
public void enqueue_new_orders(QueueSession jms_session, BolOrder new_order)
{
QueueSender sender;
Queue queue;
ObjectMessage obj_message;
}
try
{
/* get a handle to the new_orders queue */
queue = ((AQjmsSession) jms_session).getQueue("OE", "OE_neworders_que");
sender = jms_session.createSender(queue);
obj_message = jms_session.createObjectMessage();
obj_message.setJMSCorrelationID("RUSH");
obj_message.setObject(new_order);
jms_session.commit();
}
catch (JMSException ex)
{
System.out.println("Exception: " + ex);
}
AdtMessage
An AdtMessage is used to send a message that contains a Java object that maps to
an Oracle Object type. These objects inherit from Message and add a body
containing a Java object that implements the CustomDatum or ORAData interface.

CustomDatum and ORAData interfaces
