I am using Drools 5.5 with persistence. If I create a session like: ksession = kbase.newStatefulKnowledgeSession(null,env); My logger works as expected: KnowledgeRuntimeLogger klogger = KnowledgeRuntimeLogger.newFileLogger(ksession,"run") HOWEVER, if I create the ksession like: ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase,null,env) my klogger file (run.log) is never created. Is this expected? Is there a way to get a runtime log using persistence? Thanks! -- View this message in context: http://drools.46999.n3.nabble.com/Does-KnowledgeRuntimeLogger-work-with-p...
