You can do the first thing, or you can use two threads: one that calls Rete.runUntilHalt(), which fires all active rules, then sleeps until new activations are available, and a second thread that asserts the input data points as facts as they become available. Using two threads would be slightly more complicated, but somewhat more efficient. --------------------------------------------------------- Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- 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!)
