There's a wide range of Java solutions: http://www.manageability.org/blog/stuff/rule_engines/view Most of them are over-specified for our relatively modest requirements. Plus, I've never really looked into the practicality of using Java libraries with Php 4. The only practical option I've found is this project: http://sourceforge.net/project/showfiles.php?group_id=117793 ... but it's only got a couple of developers and I'm wary of betting my business on a library like this. Do you know a better way? With our modest needs, I'd much prefer to find a native solution, (if such a thing exists) rather than add a layer of complexity and potential unreliability by inter-operating with the Java VM. -------------------- Geoff Caplan Creative Living -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
