You know, it's funny, but I've never seen an ILOG JRules question here at the Ranch. I suspect it's actually because their sales model is like Oracle's -- they want to sell you not only a product, but also (mostly?) consultants who implement it for you.
Anyway, we
do get a steady trickle of questions about
Jess (a competing rule engine) in the JavaRanch "Other Java Products and Servers" forum, and those tend to get answered quickly. I'll move this over there for you, and we'll see how you make out.
