There seem to be two issues here.. - one is that loading is "too slow" for a "large number" of rules --> could you provide some figures? :) There may also be ways to reduce the number of rules, but we'd need to know more about your usecase. Please also consider that Drools is optimized for execution, so the tradeoff is a heavier startup phase, where many optimizations are pre-calculated - the other is that you don't want to restart the application server when you change the rule --> please read the manual at the "KnowledgeAgent" section and see if that helps Best Davide -- View this message in context: http://drools.46999.n3.nabble.com/Loading-a-large-number-of-rules-is-too-...
