InvocationTargetException on creating StatefulKnowledgeSession

lauradp Dec 5, 2013 4:56 AM

Hello everybody,

I'm facing a strange problem and I'm wondering if someone has encountered the same issue.

I'm trying to start a jbpm workflow from a jms consumer (i.e. after receiving a jms message), but on creating a StatefulKnowledgeSession

if (persistenceEnabled) {

Environment env = KnowledgeBaseFactory.newEnvironment();

EntityManagerFactory emf = Persistence.createEntityManagerFactory("org.jbpm.persistence.jpa");

KnowledgeSessionConfiguration config = KnowledgeBaseFactory.newKnowledgeSessionConfiguration(properties);

env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);

BitronixTransactionManager transactionManager = TransactionManagerServices.getTransactionManager();

env.set(EnvironmentName.TRANSACTION_MANAGER, transactionManager);

env.set(EnvironmentName.TRANSACTION, transactionManager.getTransaction());

if (sessionId == -1) {

ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env);

} else {

ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, config, env);

ksession.dispose();

ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env);

}

boolean humanTaskEnabled = properties.getProperty("taskservice.enabled", "false").equalsIgnoreCase("true");

if (humanTaskEnabled) {

String transport = properties.getProperty("taskservice.transport", "hornetq");

if ("mina".equals(transport)) {

ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new MinaHTWorkItemHandler(ksession));

} else if ("hornetq".equals(transport)) {

ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new AsyncHornetQHTWorkItemHandler(ksession, true));

} else {

throw new RuntimeException("Unknown task service transport " + transport);

}

I get a java.lang.reflect.InvocationTargetException. If I use the same code, but drive the workflow using a webService, all works fine.

See persistence.xml attacched.

Can anyone help me?

Are you sure you have properly configured transaction manager?

this line:
BitronixTransactionManager transactionManager = TransactionManagerServices.getTransactionManager();
produces your error:
javax.naming.NameNotFoundException: java:comp/UserTransaction

Hi Viktor,
Thanks for your answare. No, I get the error on this line:

ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, config, env);

How can I chack that the transaction manager is properly configured?

synclpz Dec 9, 2013 11:59 AM (in response to lauradp)

Sorry, i misunderstood the trace... Transaction manager lookup is ok, because you invoke transactionManager.getTransaction() and do not get NPE :-)

Could you check that "transactionManager.getTransaction()" does not return null? Seems like it tries to lookup java:comp/UserTransaction upon newStatefulKnowledgeSession being called. May be if env.set(EnvironmentName.TRANSACTION, transactionManager.getTransaction()); sets not null it would not try to lookup? I don't really know, but you may try...

Yes, it returns null

if I avoid passing transaction to my environment I get the same error.

Seems like issues with Bitronix. It should not return null on getTransaction() or you are not using it the right way :-)
