How do I configure iBiff to publish events for Messaging server?

I tried running the supplied sample programs (JBiff.java and JmsSample.java). I get the "Waiting for notification" message but no notification.

Did you load the ibiff plugin? It is not automatically enabled. Please see Appendix C of the iMS 5.2 Admin Guide, http://docs.iplanet.com/docs/manuals/messaging/ims52/ag/event.htm#17522
