For people thinking about using Jess: Yes, it's still got a fairly tight
license. You can download and play with a binary trial version for 12 days
or so. After that you need to ask for and process a licensing agreement
stating that you're doing research or working out a means of paying for it
if you're a commercial user. My lab director and I were just discussing
how to work with the license to use Jess in a class on intelligent
systems. A servlet providing a Jess service is one of the things we're

I guess the argument is that this license allows Sandia Labs to continue
to support development of Jess. Whereas CLIPS hasn't been in active
development for years (AFAIK), a new version of Jess with significant
improvements was put out just yesterday.
