Hi all,
I have been looking for a solution to something similar. I think the objective is to have an identifying property (an ID maybe) in all the beans. This is more related to his (Krishna Chaitanya's )first question. If we can get handle to individual objects we can track them using that property.
His second question though seems to be geared toward getting a list of partially satisfied rules. For goal oriented rules maybe. (?)

Subject: Re: JESS: Question about Defrule
The getToken() method of Activation returns a jess.Token, which is
basically a list of facts that match a rule's LHS.
There is no way to get a list of all the rules for which at least one
fact is matched. Jess just doesn't work like that.
I should ask you, though, why you want to do all this? Maybe you'd be
more successful if you told us what you wanted to accomplish in more
general terms. There's probably a better way to do whatever it is.
