Queue Sender
JMS Point-to-Point Model Features
A client uses a QueueSender to send messages to a queue. A QueueSender is
created by passing a queue to a session’s createSender method. A client also has
the option of creating a QueueSender without supplying a queue. In that case a
queue must be specified on every send operation.
A client can specify a default delivery mode, priority and time-to-live for all
messages sent by the QueueSender. Alternatively, the client can define these
options on a per message basis.
Example Code
In the BooksOnline application, new orders are to be sent to the new_orders_
queue. After creating a JMS connection and session, we create a sender:
public void enqueue_new_orders(QueueSession jms_session, BolOrder new_order)
{
QueueSender sender;
Queue queue;
ObjectMessage obj_message;
}
Queue Receiver
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);
sender.send(obj_message);
jms_session.commit();
}
catch (JMSException ex)
{
System.out.println("Exception: " + ex);
}
A client uses a QueueReceiver to receive messages from a queue. A
QueueReceiver is created using the session’s createQueueReceiver method.
A QueueReceiver can be created with a message selector. This allows the client to
restrict messages delivered to the consumer to those that match the selector.
