Bob, My requirements in order:
1) Ease of use (many times the ultimate users of infrastructure code are not that advanced) 2) Speed is a factor, however it will be qualitative. (slow will depend on the user) In my case with the shopping cart that has a volume restriction. Speed will be an issue, but how much depends on the feel of it.

I haven't benchmarked drools at all against JEOPS, Jess or JRules. I imagine that possibly drools will be slow in comparison, due to the run-time interpreted nature of the condition matching and action execution. Quick straw poll: What's the most important factor to each of you? a) Speed of matches (ie, how long does assertObject(...) block, when the asserted object does and does not create a rule match). b) Ease of use. c) Run-time extensibility. d) Other? (Please specify) Note that possibly many times, an assertObject(...) call will simply drop an object in, but not actually create a match. Sometimes it will, and then the Action portion of the match will take the most time. Since we use Rete (actually, Rete-OO), we are following the efficient algorithm for matching, and avoid execution redundant predicates repeatedly. Anyhow, folks? Which do you consider the most important? -bob _______________________________________________ drools-interest mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/drools-interest _______________________________________________ drools-interest mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/drools-interest
