Hi, Thanks for the advice, I took the code and compile it in JessTab in Protigi, and fix error from there. This is the Java code which can be compiled.

Thanks again for the pointers. r.executeCommand("(do-backward-chaining adv-type)"); r.executeCommand("(assert (adv-attr target-audience-demographically))"); r.executeCommand("(assert (adv-attr marketing-budget-less-than-RM5K))"); r.executeCommand("(assert (ask adv-type))"); r.executeCommand("(defrule rule1" + "(ask adv-type)" + "(adv-type ?x)" + "=>" + "(assert (done success2)))"); r.executeCommand("(defrule rule2" + "(need-adv-type ?)" + "(adv-attr target-audience-demographically)" + "(adv-attr marketing-budget-less-than-RM5K)" + "=>" + "(assert (adv-type newspaper-advertisement)))"); __________________________________ Do you Yahoo!?
