I'm bumping this question for general interest on other possible solutions, and to give my two cents. The closest I was to getting this feature in Drools 6 from the public APIs, is to use a persistent session. Then, when I loaded an existing session, I would pass a newly created KieBase, like this KieStoreServices kstore = KieServices.Factory.get().getStoreServices(); KieBase kbase = ...; //create a Kie Base Environment env = ...; //create an environment KieSession ksession = kstore.newKieSession(kbase, null, env); Integer sessionId = ksession.getId(); KieBase kbase2 = ...; //updated Kie base KieSession ksessionReloaded = ks.loadKieSession(kbase2, null, env); ksession and ksessionReloaded would be the same working memory and agenda, but the kie base they work with would change. Hope this helps, but I hope more for an alternative -- View this message in context: http://drools.46999.n3.nabble.com/Dynamically-loading-rules-in-KieBase-tp...
