[rules-users] Drools Human Task Service Persistence

[loumimi]

Thank your for your quick reply,

I'm using only the jboss transaction manager, it works fine for me now, I
can create the session but I have now another bug, it  appear when I start
the workFlow

ksession.startProcess( "com.sample.ruleflow" );

Here is my stacktrace

java.lang.NullPointerException

I think It happen  because I did not define a transaction manager in my code
env.set(EnvironmentName.TRANSACTION_MANAGER, XXXX); 

I don't know what can I put in instead EnvironmentName.TRANSACTION_MANAGER
of XXXX. Do you have any idea ?

EntityManagerFactory emf =  Persistence.createEntityManagerFactory(
"org.drools.persistence.jpa" );
Environment env = KnowledgeBaseFactory.newEnvironment();
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );
//env.set(EnvironmentName.TRANSACTION_MANAGER, XXXX); 
StatefulKnowledgeSession ksession =
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );
ksession.startProcess( "com.sample.ruleflow" );
ksession.fireAllRules();
ksession.dispose();

Thank you very much

Regards
