Working with IBM webMethods Messaging Triggers
IBM webMethods messaging trigger subscribes to one or more publishable document types and processes instances of those document types. IBM webMethods messaging trigger can receive documents published to a webMethods messaging provider (IBM webMethods Universal Messaging or IBM webMethods Broker) or documents published locally by Integration Server on which the trigger resides.
Each IBM webMethods messaging trigger is composed of two basic pieces:
A subscription to one or more publishable document types
A service that processes instances of those publishable document types.
When IBM webMethods messaging trigger receives a document to which it subscribes from the messaging provider, Integration Server passes the document to the specified service and then invokes the service.
Note:
Prior to Integration Server and IBM webMethods Designer versions 9.5 SP1, IBM webMethods messaging trigger was called IBM webMethods Broker/local trigger.
