Would that be possible that you have drools dependencies twice? (just an idea...) -----Message d'origine----- De : rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] De la part de timpe Envoyé : vendredi 28 mai 2010 10:50 À : rules-users(a)lists.jboss.org Objet : [rules-users] History log with mySQL Database I'm trying to establish a history log for my Flow. I'm using version 5.0.1 and I set up my project with maven. So I'm using drools-bam-5.0.1.jar Inside this archive there is a META-INF folder containing the hibernate-instructions. How can I reconfigure these settings? I tried to put the hibernate.cfg.xml and the AuditLog.hbm.xml into the META-INF-folder in my root Project without success (default Settings from jar-file are used). While using the drools-bam archive (jar from the maven-repository), I got the following error: Not supported session in logger: class org.drools.process.command.impl.CommandBasedStatefulKnowledgeSession I debugged it and found out that he jumps out in WorkingMemoryLogger in Line 136: else if (session instanceof CommandBasedStatefulKnowledgeSession) { WorkingMemoryEventManager eventManager = ((CommandBasedStatefulKnowledgeSession) session).getCommandService().getSession(); eventManager.addEventListener( (WorkingMemoryEventListener) this ); eventManager.addEventListener( (AgendaEventListener) this ); eventManager.addEventListener( (RuleFlowEventListener) this ); eventManager.addEventListener( (RuleBaseEventListener) this ); } else { The Session is an instance of org.drools.process.command.impl.CommandBasedStatefulKnowledgeSession When I add the source-File of the WorkingMemoryLogger into my project, then this error does not occur. Any Ideas? Thanks Timo -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/History-log-with-mySQ...
