Hi JBPM,

i meet these Exception while i try to get a Session:

EntityManagerFactory emf = jbpmEMF;

KnowledgeBase kbase = this.getKnowledgeBuilder().newKnowledgeBase();

Environment env = KnowledgeBaseFactory.newEnvironment();

env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );

env.set( EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager() );

env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() );

StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
