One version of the Change notification framework is here: http://www.wirehose.com/download/ And "ERChangeNotificationJMS contributed by Tatsuya Kawano. Adaptation of David Neuman's change notification framework except instead of having every WOApplication broadcast to every other WOApplication using a WOHTTPConnection this implementation uses a JMS publish/subscribe system. This version uses Exolab's OpenJMS implementation although it should be fairly straight forward to adapt to any other JMS provider." here: http://wonder.sourceforge.net/ (You have to poke around a bit...)
