Hi, I'm stuck on this "simple" problem for two days now and I couldn't find the answer anywhere. I have a simple ruleflow (Start -> Human Task -> End) and when I start the process it breaks like this: **************************************************************************** [2010:04:102 15:04:971:exception] Uncaught exception on Server java.lang.NoSuchMethodError: org.drools.util.ChainedProperties.<init>(Ljava/lang/String;)V at org.drools.task.service.SendIcal.<init>(SendIcal.java:73) at org.drools.task.service.SendIcal.getInstance(SendIcal.java:67) at org.drools.task.service.TaskServiceSession.addTask(TaskServiceSession.java:138) at org.drools.task.service.TaskServerHandler.messageReceived(TaskServerHandler.java:88) .... **************************************************************************** I'm using drools 5.1.0M1 and the "drools.email.conf" is in the META-INF directory.

Hmmm, it still doesn't work. The version of the drools-api.jar is 5.1.0SNAPSHOT (it's part of the "Drools 5.1.0 runtime" in eclipse 3.5.2) and the task part is drools-process-task-5.1.0.M1.jar. I'll try to compile everything from drools-5.1.0.M1-src.zip and see if that helps. -- View this message in context: http://n3.nabble.com/Drools-Flow-Problem-with-Human-Task-tp713533p715521....

OK, I fixed that problem. But now I have another one - I've set up persistence for processes (flow) just like the documentation says, there are no problems with configuration and hibernate created those 5 tables. Then I start my test (in this case my custom class, no JUnit) I get this: ************************************************************************ 14:54:58,968 WARN Configuration:490 - cannot get this JVM unique ID.

No, I have drools-process-task in my dependencies and orm.xml file is in the META-INF directory (matching versions this time :-). I've also checked orm.xml and it has all those named queries reported in error log. I'm worried about "org.hibernate.hql.ast.QuerySyntaxException: Task is not mapped" part of the error log. What can I do about that?
