Did you set the event mask? (jess.Rete.setEventMask(JessEvent.FACT)
YOu have to set the event mask to specify what kind of events you want
to receive.

Hi,
I am developing an academic application with Jess & Jade.
Is there any simple way to get all facts which are just inserted?
Iterating over all the facts in working memory would be very
inefficient, right?
I actually tried to add a JessListener
public class KitchenJessListener implements JessListener{
public void eventHappened(JessEvent event) throws JessException {
Object o=event.getObject();;
if(event.getType()== JessEvent.FACT) {
o=event.getObject();
}
System.out.println("event:"+o.toString());
}
} using addJessListener function,
but the function is never invoked, though I insert new facts to the
working memory in run time.
