I found the message from Omni's WebObjects-Dev list I mentioned on
Apple's WebObjects-Dev list last night. Looks like Alexander Lamb has
been able to integrate the Jess rule engine into a WebObjects
application.
The link he's replying to has a list of rule engines, which you might
also find useful if a rule engine (instead of a full Lisp/Prolog
implementation) will serve your application's needs.
Good luck!

Salut Joel!
We tried Jess. It integrates perfectly well with WebObjects.
Obviously, the
problem will be more "what are you trying to achieve with a rule
engine"
than "how does it integrate". Indeed, Jess being pure Java and having
all
its interface exposed in Java, integration is not a problem.
For our tests, we decided to use on Java objects as assertions in Jess
and
not Jess asserts. The rules where in Jess and operating on the Java
objects
that had been asserted.
The problem you might run into is: since Jess (like other rule engines)
don't handle transactions, when do you run the rule engine and how do
you
avoid collision between several session in an app sharing a Jess
database.
Obviously you can have one Jess database per session but it seems a
not very
good idea in most cases.
You may want to look at the discussion list archive (you'll find a link
somewhere at http://herzberg.ca.sandia.gov/jess/) and look at my posts
which
(sometimes naively) explore those issues.
Hope this helps,
Alex

Experiences and advices would be greatly helpfull. Thanks!
