"Unable to load session snapshot" To view the discussion, visit: http://community.jboss.org/message/611223#611223 -------------------------------------------------------------- Hi, i have a problem about persistence that i don't know how to resolve it. Particularly i'm not able to load a session with some facts into an entry point of working memory. I have attached a very simple eclipse project in which there is only one rule file and one java class: In the rule file i define a entry-point called "eventStream" In java class inside a single transaction i: 1. create a StatefulKnowledgeSession 2. add some facts in entry point 3. dispose session After that in another transaction i try to load the session, but the following exception is thrown java.lang.IllegalStateException: java.lang.reflect.InvocationTargetException at org.drools.persistence.jpa.KnowledgeStoreServiceImpl.buildCommanService(KnowledgeStoreServiceImpl.java:103) at org.drools.persistence.jpa.KnowledgeStoreServiceImpl.loadStatefulKnowledgeSession(KnowledgeStoreServiceImpl.java:71) at org.drools.persistence.jpa.JPAKnowledgeService.loadStatefulKnowledgeSession(JPAKnowledgeService.java:118) at jpaSession.TestJPASession.loadKnowledgeSession(TestJPASession.java:148) at jpaSession.TestJPASession.testLoadSessionWithFactsInEntryPoint(TestJPASession.java:97) at jpaSession.TestJPASession.main(TestJPASession.java:65) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:532) at org.drools.persistence.jpa.KnowledgeStoreServiceImpl.buildCommanService(KnowledgeStoreServiceImpl.java:88) ... 5 more Caused by: java.lang.RuntimeException: Unable to load session snapshot at org.drools.persistence.SessionMarshallingHelper.loadSnapshot(SessionMarshallingHelper.java:96) at org.drools.persistence.SingleSessionCommandService.initKsession(SingleSessionCommandService.java:196) at org.drools.persistence.SingleSessionCommandService.(LeftTuple.java:144) at org.drools.marshalling.impl.InputMarshaller.readLeftTuple(InputMarshaller.java:599) at org.drools.marshalling.impl.InputMarshaller.readFactHandles(InputMarshaller.java:372) at org.drools.marshalling.impl.InputMarshaller.readSession(InputMarshaller.java:220) at org.drools.marshalling.impl.DefaultMarshaller.unmarshall(DefaultMarshaller.java:92) at org.drools.persistence.SessionMarshallingHelper.loadSnapshot(SessionMarshallingHelper.java:91) ... 12 more the problem occurs only when i dispose the session with some facts in entry-point, if i insert some facts in workingmemory everything works fine. does anyone have any suggestion? i'm using jBPM 5.1 CR1 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/611223#611223] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&containerType=14&container=2034]
