Barry, I started a project like this, but lost the code :( The idea was to hava JavaFact interface that allowed a bean to register one or more working memories, and it would "notify" all working memories on change. The JavaFact interface would be woven into the beans at load time. I was going to take it one step further to allow systems like Spring to control the "monitoring", i.e. the spring conf file would specify which working memories would be registered on beans during construction - so spring can manage the full life cycle of working memories and facts, invisibly to the user. Maybe you could work on re-doing this work for ? :) Mark Barry Kaplan wrote: > I'm working on an implementation that uses AspectJ to introduce the > required property change listeners.
