Hi, Thank you for the response. In our case most of the calculations are on the RHS side of the rule. Does that mean we should write our calculations/formulas in Jess? Also, we are very familiar in Java than in Jess. At this point we are hard pressed for time. That is the reason we are trying to understand if there are any performance implications in using java/jess.

If the computations are non-trivial and called often -- especially from the left-hand-sides of rules -- then the performance will be better if the calculations are written as Java Userfunctions. Jess was designed to make it easy to extend; writing Userfunctions is very simple, so there's little reason not to do it. --------------------------------------------------------- Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://www.jessrules.com -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
