Is Jess The Best Rules Engine Fit For J2EE?

I’m a little disappointed that no real straight answers came from my last
entry: Uncommented
Bytes: Jess Architecture in a J2EE Environment

So now I’m lead to believe that Jess may truly be difficult to integrate into our
highly scalable, distributed, enterprise architecture. Wrapping Jess in a custom RMI server
doesn’t seem very elegant to me, but as of now it looks like the only solution. As I mentioned
in the comments of my other post, if Jess is the reference implementation for JSR 94, wouldn’t
they come up with a better way to integrate into a J2EE environment?
