Release 10.1A: OpenEdge Development:
Messaging and ESB

Receiving messages from a PTP queue

The following general steps outline how a 4GL application receives a message from a queue:

The application obtains a handle to the PTP Session object.
The application creates a Message Consumer object by calling the createMessageConsumer procedure.
The application calls the receiveFromQueue procedure in the Session object with the name of a queue and the Message Consumer handle as input parameters.
The application executes a WAIT–FOR statement (or a waitForMessages procedure call) and processes incoming messages and other 4GL events.
The application deletes the messages after it finishes using them.
