To fill in my question below If I add these:
(deftemplate artifact(declare (from-class factclasses.artifact ))) (deftemplate painting extends artifact) I am getting Jess reported an error in routine Defmodule.addDeftemplate. Message: Cannot redefine deftemplate MAIN::painting. What is going wrong? Hello again, I have the Java classes painting,statue which extend the class artifact. I need to model them in deftemplates in such a way that I could get both of instances with one defrule: (defrule checkAPP "Setting a property for all instances" (artifact (OBJECT ?art) ) => (?art setDatatypeProperty_1 "OK") (update ?art) ) How I can do that? thanks in advance, John. -------------------------------------------------------------------- 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!)
