Hi Folks, The latest release of Jess, the programmer's rule engine for the Java platform, is available for download at the usual place:
http://herzberg.ca.sandia.gov/jess/download.shtml There are a number of bug fixes in this release (6.1a3) but the most exciting feature is full support for arbitrary nested conditional elements, greatly increasing the expressive power of Jess's rule language. Another useful new feature is that when you construct a Rete object, you can specify the ClassLoader that it should use to load your classes -- very handy when embedding Jess in an app server or other complex environment with multiple class loaders. >From the change log: Fixed a bug in save-facts (thanks Scott Trackman). Fixed deadlock problem in retract/undefinstance (thanks Blaine Bell.) Mihai Barbuceanu helped modernize the "bag" command. Various API enhancements. New Rete constructor with "app-object" argument. Massive refactoring of rule compiler to handle arbitrarily nested AND and NOT CEs in a new, simpler way; universal quantifiers are now handled correctly. Fixed a bug with the logical CE when adding new rules to a running system. Undefinstanced, nonserializable Beans now no longer prevent Rete serialization (thanks James Gallogly and Alan Moore. There have been a few recent administrative changes in the Jess universe: the Jess mailing list is now moderated and thus spam and virus free, and the Jess web site has a new stylesheet to make it easier on the eyes.
