Drools flow persistence - No active JTA transaction on joinTransaction call_问答_开发者

I've been trying to configure persistence to work with drools flow on JBOSS 6.0.0.Final by following the documentation Drools-Flow-Persistence but I keep getting a exception as below (although hibernate DOES create the database schema):

My code running a ruleflow:

try {
    KnowledgeBase kbase = readKnowledgeBase();
    // 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 );
    // create a new knowledge session that uses JPA to store the runtime state
    StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );
    int sessionId = ksession.getId();
    // invoke methods on your method here
    ksession.startProcess("com.sample.bpmn.hello");
    ksession.dispose();
    } catch (Throwable t) {
        t.printStackTrace();
    }

I have put the mysql-connector-java-5.0.8-bin.jar and btm-1.3.2.jar in "%JBOSS_HOME%\common\lib" directory

What am I missing? I get the above exception (even with H2 db), but hibernate does successfully generate the database schema, any help will be appreciated.

In your persistence.xml, you seem to be referencing the bitronix transaction manager while I suspect you want to use the JBoss transaction manager if you run this as an application on JBoss AS:
