Hi All, I have a problem refreshing the sateful knowledge session whenever there is a change in the rules assets int he guvnor. Below is my code used for configuration StatefulKnowledgeSession ksession = null; KnowledgeAgentConfiguration kconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); config.setOption( EventProcessingOption.STREAM ); KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase( config ); kconf.setProperty("drools.agent.newInstance" , "false"); KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("MyAgent1",kbase, kconf); kagent.applyChangeSet(ResourceFactory.newUrlResource(" http://127.0.0.1:8380/drools-guvnor/LDIChangeSet.xml")); kbase = kagent.getKnowledgeBase(); ksession = kbase.newStatefulKnowledgeSession(); I've a session where I've inserted thousands of facts. Whenever there is change in the rule base Do I need to reinsert all the facts using the new knowledgeBase? Any help would be appreciated. Thanks in advance. -- cheers Sumatheja Dasararaju
