Release 10.1A: OpenEdge Development:
Messaging and ESB

Preparing to receive messages

In the following example, the 4GL application begins listening on the queue and prepares to receive messages from the queue:

Preparing to receive messages 

RUN receiveFromQueue IN ptpsession (“myQueue", ?, consumerH). RUN startReceiveMessages IN ptpsession. /* Wait to receive the messages. */ WAIT-FOR u1 OF THIS-PROCEDURE.

The Message Consumer (consumerH handle) listens on myqueue and handles messages using the myintproc internal procedure. The startReceiveMessages procedure starts receipt of incoming messages.
