We have hundreds of formulae/calculations to be performed during the process of costing. We were just wondering if these formulae/ calculations should be coded in JESS or as JAVA functions and then be called from 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.
