Release 10.1A: OpenEdge Development:
Messaging and ESB

Creating a message handler process

A message handler process the incoming message from the Message Consumer. When an incoming JMS or error message is received, the message handler is called automatically so that the application can process the message. The 4GL programmer creates a message handler using the messageHandler procedure. The 4GL application passes context to the message handler using the setApplicationContext procedure.

Table 4–21 lists procedures for getting message handler properties and type of message being handled:
