The situation would be that objects _created in the Java-side of the application_ would be "used" in the rules, that includes method calls. In my example external objects were consumer and market. Since I don't know whether this is relevant, let's add the complexity that we are iterating over a collection of consumer agents in the Java code and firing that rule in each iteration. Could the corresponding Jess variables be instantiated with each corresponding JavaBean in each iteration? -- fxn -------------------------------------------------------------------- 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!)
