To enable Messaging Server to produce notifications to Message Queue or the Event Notification Service, you must configure a plug-in for that service:
The JMQ notification plug-in allows you to deliver notification messages to the Message Queue broker.
The iBiff plug-in allows you to publish notification events to the Event Notification Service.
For information on how to load the iBiff plug-in and configure the Event Notification Service, see “Appendix B: Administering Event Notification Service in Messaging Server,” in the Sun Java System Messaging Server Administration Guide.
