Make sure it is configured and you only use ASCII characters. Will use IP address instead (unsafe for production usage!). Now i try to activate the history log like i say in my first post. But i don't know how to do this. i try with this : JbpmHelper.getKnowledgeBase().addKnowledgePackages(knowledgePackages);                                                             JPAWorkingMemoryDbLogger logger = new JPAWorkingMemoryDbLogger(JbpmHelper.getKnowledgeSession());                                                             JbpmHelper.getKnowledgeSession().startProcess("com.sample.bpmn.hello");                                                             logger.dispose(); But i have this exception: java.lang.NullPointerException           at org.jbpm.process.audit.JPAWorkingMemoryDbLogger.addProcessLog(JPAWorkingMemoryDbLogger.java:90)           at org.jbpm.process.audit.JPAWorkingMemoryDbLogger.logEventCreated(JPAWorkingMemoryDbLogger.java:65)           at org.drools.audit.WorkingMemoryLogger.filterLogEvent(WorkingMemoryLogger.java:196)           at org.drools.audit.WorkingMemoryLogger.beforeProcessStarted(WorkingMemoryLogger.java:421)           at org.drools.event.ProcessEventSupport.fireBeforeProcessStarted(ProcessEventSupport.java:40)           at org.jbpm.process.instance.ProcessRuntimeImpl.startProcessInstance(ProcessRuntimeImpl.java:167)           at org.jbpm.process.instance.ProcessRuntimeImpl.startProcess(ProcessRuntimeImpl.java:138)           at org.jbpm.process.instance.ProcessRuntimeImpl.startProcess(ProcessRuntimeImpl.java:130)           at org.drools.common.AbstractWorkingMemory.startProcess(AbstractWorkingMemory.java:1077)           at org.drools.impl.StatefulKnowledgeSessionImpl.startProcess(StatefulKnowledgeSessionImpl.java:315) Best regards, Florent -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/739721#739721] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
