Re: JESS: Is Jess still alive, and Jess In Action
Hi Paul, I have to agree with everyone here. I've enjoyed working with Jess since about version 2.0, and have been actively supporting it since 6.0 onward. Ease of use, stability, and robustness have been its hallmarks. Don't let the LISP syntax of the Jess language dissuade you. Once you do a significant amount of non-trivial development, you will come to appreciate the Jess language's LISP roots. IMHO our community is one-of-a-kind in the software world. You won't find a more knowledgeable and friendly bunch.

Hi, We're looking at a couple of Java rules engines, Jess among them. It's been a couple of years since the site has been updated - is Jess still under active development? I've started reading through Jess In Action. The book was published in 2003 - is it still applicable to the 2008 version of Jess? Thanks, Paul

Re: JESS: Is Jess still alive, and Jess In Action
Jess in Action is still valid; there are some newer features since then, and some newer best practices, but nothing in the book is *wrong*. The release notes in the Jess 7.0 manual explicitly address the 6.x - 7.x transition and things that you might want to change, so they serve as a nice addendum to the book. Jess is still supported, and occasional updates are still being made, but active development of new features is on hiatus for now.

Re: JESS: Is Jess still alive, and Jess In Action
Hi Paul, We have two applications that are deployed operationally. One is a real time data driven decision support system processing health data. Its been in operation for two years, running non-stop without an error. The second is an operational app that provides risk assessment for hospital acquired illness. It runs in a hospital environment and has been operation for just over a year. Both apps process a large volume of data. The larger rule base is just over three hundred rules and has a knowledge base of just over 800k facts. We tested a number of rule systems and found JESS to be the best suited to meet our system requirements.
