Hi All,
follwoing is the code i used to get the session using JPAKnowledgeService.newStatefulKnowledgeSession.
table for the mentioned classes are getting created, after that JPAKnowledgeService.newStatefulKnowledgeSession() method throws following exception....
EntityManagerFactory emf = Persistence.createEntityManagerFactory( "org.drools.persistence.jpa" );
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
env.set( EnvironmentName.TRANSACTION_MANAGER, TransactionManagerServices.getTransactionManager() );
StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );
-------------------------
persistence.xml
i copied only persistent unit part...
