[rules-users] How to add more knowledge to Stateful session, post start-up

At present I set up a ksession like this: KnowledgeBase kbase = < call method that loads several rule files and process flow files via kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()) > StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); Then I set globals, start one of the processes, assert facts, fire rules etc etc Later on rules fire that start some or all of the remaining pre-loaded processes, as required Is the best way to do it? Instead should I be loading additional rule and/or process files in to the ksession on the fly, rather than at the beginning, for performance/scalability reasons? (I couldn't work out how to do this without overwriting ksession). Thanks in anticipation, John Shepherdson
