hi all,
well this is kind of general question but as there are Java APIs for this i would like to put it here.
my questions are,
1. what is a 'rule engine'?
2. what are good ones available in the market? (paid or free)
3. how much research has gone into Java based rule engines?
4. what are the points/issues we should consider when we want to evaluate a given rule engine?
if anybody have any link or pointers , it would be a great help.
meanwhile, i am with my best friend looking for more information - Google..he he :-)
regards
maulin.

I don't know too much about it, but check out Jess. To be honest I only became aware of it because Manning is coming out with a book on it.

Rules engines are very cool beasts. They are very complicated but a well written one is extremely flexible. The idea behind a rules engine is to provide a framework for creating business rules.

thanks Jason.
i'm trying to obtain paper by Dr. Charles Forgy about the Rete Algorithm if i can get it from anywhere. Rete is the algorithm used by almost each rule-based system originally deviced by Dr. Charles Forgy and it is the most efficient algorithm so far in rule-based systems.
just wondering - why they named the project as "Jess"?
regards
maulin.

Hey Thomas,
Could you point us to some literature on the subject?

My guess is that it has something to do with Java Expert System, but that's just a guess.
