Re: [rules-users] Drools Human Task Service Persistence

Hello, I switch from drools 5.0.1 to drools 5.1.0, the problem is resolved, I m using the bitronix transaction manager, I kept transaction-type to "RESOURCE_LOCAL". So every things seem to be good, I have no exception. But no data is persisted in my database. So I tried to change the transaction type to JTA but I m getting the exception bellow : SEVERE: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session) org.hibernate.AssertionFailure: Transaction MARKED_FOR_JOINED after isOpen() call at org.hibernate.ejb.AbstractEntityManagerImpl.joinTransaction(AbstractEntityManagerImpl.java:465) at org.hibernate.ejb.AbstractEntityManagerImpl.postInit(AbstractEntityManagerImpl.java:82) at org.hibernate.ejb.EntityManagerImpl.<init>(EntityManagerImpl.java:61) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:39) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:34) at org.drools.persistence.session.DefaultJpaManager.getApplicationScopedEntityManager(DefaultJpaManager.java:37) at org.drools.persistence.session.SingleSessionCommandService.<init>(SingleSessionCommandService.java:124) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at org.drools.persistence.jpa.impl.KnowledgeStoreServiceImpl.buildCommanService(KnowledgeStoreServiceImpl.java:119) at org.drools.persistence.jpa.impl.KnowledgeStoreServiceImpl.newStatefulKnowledgeSession(KnowledgeStoreServiceImpl.java:57) at org.drools.persistence.jpa.JPAKnowledgeService.newStatefulKnowledgeSession(JPAKnowledgeService.java:109) at com.sample.ProcessTest.main(ProcessTest.java:69) java.lang.IllegalStateException: java.lang.reflect.InvocationTargetException at org.drools.persistence.jpa.impl.KnowledgeStoreServiceImpl.buildCommanService(KnowledgeStoreServiceImpl.java:133) at org.drools.persistence.jpa.impl.KnowledgeStoreServiceImpl.newStatefulKnowledgeSession(KnowledgeStoreServiceImpl.java:57) at org.drools.persistence.jpa.JPAKnowledgeService.newStatefulKnowledgeSession(JPAKnowledgeService.java:109) at com.sample.ProcessTest.main(ProcessTest.java:69) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at org.drools.persistence.jpa.impl.KnowledgeStoreServiceImpl.buildCommanService(KnowledgeStoreServiceImpl.java:119) ... 3 more Caused by: java.lang.RuntimeException: Could not commit session at org.drools.persistence.session.SingleSessionCommandService.<init>(SingleSessionCommandService.java:135) ... 8 more Caused by: org.hibernate.AssertionFailure: Transaction MARKED_FOR_JOINED after isOpen() call at org.hibernate.ejb.AbstractEntityManagerImpl.joinTransaction(AbstractEntityManagerImpl.java:465) at org.hibernate.ejb.AbstractEntityManagerImpl.postInit(AbstractEntityManagerImpl.java:82) at org.hibernate.ejb.EntityManagerImpl.<init>(EntityManagerImpl.java:61) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:39) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:34) at org.drools.persistence.session.DefaultJpaManager.getApplicationScopedEntityManager(DefaultJpaManager.java:37) at org.drools.persistence.session.SingleSessionCommandService.<init>(SingleSessionCommandService.java:124) ... 8 more I tried to add the objects you mentioned, I added only 3, I didn't add env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY, this.txSvc.getTransactionSynchronizationRegistry()); because new InitialContext().lookup( "java:comp/env/TransactionSynchronizationRegistry" ); Return null even I add javax.transaction.TransactionSynchronizationRegistry = bitronix.tm.BitronixTransactionSynchronizationRegistryObjectFactory in my jndi.properties file here is my code UserTransaction ut = (UserTransaction) new InitialContext().lookup( "java:comp/UserTransaction" ); // create the entity manager factory and register it in the environment 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()); env.set(EnvironmentName.GLOBALS, new MapGlobalResolver()); env.set(EnvironmentName.TRANSACTION, ut); //TransactionSynchronizationRegistryHelper tsr = (TransactionSynchronizationRegistryHelper) new InitialContext().lookup( "java:comp/env/TransactionSynchronizationRegistry" ); // env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY, tsr ); // create a new knowledge session that uses JPA to store the runtime state StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env ); // start the transaction ut.begin(); // invoke methods on your method here ProcessInstance process = ksession.startProcess( "com.sample.ruleflow" ); ksession.signalEvent("Test", "Test", process.getId()); ut.commit(); ut.begin(); ksession.fireAllRules(); // commit the transaction ut.commit(); ksession.dispose(); any idea ?

(In some JTA implementations the UserTransaction and TransactionManager have the same interfaces). And to make Drools Persistence JPA works, you should put 4 or 5 objects into env, they are: env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, this.defaultPersistenceSvc.getSessionFactory()); env.set(EnvironmentName.APP_SCOPED_ENTITY_MANAGER, this.defaultPersistenceSvc.getCurrentSession()); // If you don't handle the EntityManager your self, you can omit this line. env.set(EnvironmentName.TRANSACTION_MANAGER, this.txSvc.getTransactionManager()); // java:comp/env/TransactionManager env.set(EnvironmentName.TRANSACTION, this.txSvc.getTransaction()); // java:comp/UserTransaction env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY, this.txSvc.getTransactionSynchronizationRegistry()); // java:comp/env/TransactionSynchronizationRegistry all the methods called from txSvc fetch objects from according JNDI. In my application all these JNDI objects are config-ed via Tomcat like this (in META-INF/context.xml): <Resource name="jdbc/defaultDS" auth="Container" type="javax.sql.XADataSource" factory="bitronix.tm.resource.ResourceObjectFactory" uniqueName="jdbc/defaultDS" /> <Resource name="jdbc/droolsTaskDS" auth="Container" type="javax.sql.XADataSource" factory="bitronix.tm.resource.ResourceObjectFactory" uniqueName="jdbc/droolsTaskDS" /> <Resource name="TransactionManager" auth="Container" type="javax.transaction.TransactionManager" factory="bitronix.tm.BitronixTransactionManagerObjectFactory" /> <Resource name="TransactionSynchronizationRegistry" auth="Container" type="javax.transaction.TransactionSynchronizationRegistry" factory="bitronix.tm.BitronixTransactionSynchronizationRegistryObjectFactory" /> <Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction" /> <Transaction factory="bitronix.tm.BitronixUserTransactionObjectFactory" /> -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Human-Task-Service-Persistence-t...
