Hi Pierce, You may be violating the Zen Of Jess http://herzberg.ca.sandia.gov/jess/zen.shtml here. :-D The Rete.defclass method is intended for creating a deftemplate of a JavaBean to be "shadowed" in working memory as a "shadow fact". Note that the private fields of a JavaBean correspond to the slots in a shadow-fact, and that Jess is expecting your class to be like a JavaBean (proper field names, getters and setters, etc. so that Jess can use reflection to "read" the bean) -- you certainly shouldn't pass Rete.defclass an Integer and expect this to work. Once Jess "knows" how to store your bean as a fact, then you can use that deftemplate to add shadow-facts to working memory using Rete.definstance. If you really want to try this via the API now, I recommend reading Jess In Action section 6.5 or click here http://herzberg.ca.sandia.gov/jess/docs/61/language.html#definstance_facts and work through the examples. If you do that, I'll be happy to hack through some examples with you afterward. IMHO - You're always better off learning Jess from the command line using the Jess language before trying to program Jess's API directly. Why? Because you'll develop a better feel for when it's more efficient to write Jess script, when to program the API itself, or when to integrate the two. This flexibility is what separates Jess from other rule languages and shells. Hope this helps!
