I switch from drools 5.0.1 to drools 5.1.0, the problem is resolved, I m<br>
using the bitronix transaction manager, I kept transaction-type to<br>
<div class="im">"RESOURCE_LOCAL". So every things seem to be good, I have no exception.<br>
</div>But no data is persisted in my database. So I tried to change the<br>
<div class="im">transaction type to JTA but I m getting the exception bellow :<br>

I tried to add the objects you mentioned, I added only 3, I didn’t add<br>
env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY,<br>
this.txSvc.getTransactionSynchronizationRegistry());<br>
because<br>
new InitialContext().lookup(<br>
"java:comp/env/TransactionSynchronizationRegistry" );<br>
Return null even I add<br>
javax.transaction.TransactionSynchronizationRegistry =<br>
bitronix.tm.BitronixTransactionSynchronizationRegistryObjectFactory<br>
in my jndi.properties file<br>
<br>
here is my code<br>
UserTransaction ut = (UserTransaction) new InitialContext().lookup(<br>
"java:comp/UserTransaction" );<br>
// create the entity manager factory and register it in the<br>
environment<br>
</div><div class="im"> EntityManagerFactory emf =<br>
Persistence.createEntityManagerFactory( "org.drools.persistence.jpa" );<br>
Environment env = KnowledgeBaseFactory.newEnvironment();<br>
env.set( EnvironmentName.ENTITY_MANAGER_FACTORY, emf );<br>
env.set(EnvironmentName.TRANSACTION_MANAGER,<br>
</div><div class="im">TransactionManagerServices.getTransactionManager());<br>
env.set(EnvironmentName.GLOBALS, new MapGlobalResolver());<br>
env.set(EnvironmentName.TRANSACTION, ut);<br>
//TransactionSynchronizationRegistryHelper tsr =<br>
(TransactionSynchronizationRegistryHelper) new InitialContext().lookup(<br>
"java:comp/env/TransactionSynchronizationRegistry" );<br>
//<br>
env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY, tsr );<br>
<br>
// create a new knowledge session that uses JPA to store the<br>
runtime state<br>
</div><div class="im"> StatefulKnowledgeSession ksession =<br>
JPAKnowledgeService.newStatefulKnowledgeSession( kbase, null, env );<br>
<br>
</div><div class="im"> // start the transaction<br>
ut.begin();<br>
// invoke methods on your method here<br>
</div> ProcessInstance process = ksession.startProcess(<br>
"com.sample.ruleflow" );<br>
<div><div></div><div class="h5"> ksession.signalEvent("Test", "Test", process.getId());<br>
ut.commit();<br>
ut.begin();<br>
ksession.fireAllRules();<br>
// commit the transaction<br>
ut.commit();<br>
ksession.dispose();<br>
<br>
any idea ?<br>
<br>
Thanks<br>

Subject: Re: [rules-users] Drools Human Task Service Persistence<br>
<br>
Drools Persistence JPA module must use JTA instead of local transaction.<br>
<br>
<persistence-unit name="org.drools.persistence.jpa"<br>
transaction-type="RESOURCE_LOCAL"><br>
<br>
should change to<br>
<br>
<persistence-unit name="default" transaction-type="JTA"><br>
<br>
and<br>
<br>
env.set( EnvironmentName.TRANSACTION_MANAGER, XXXXXXXXXXX );<br>
<br>
your transaction manager should be get from JNDI like<br>
<br>
UserTransaction utx = (UserTransaction)<br>
ctx.lookup("java:comp/UserTransaction");<br>
<br>
Your JBoss transaction manager component should register the UserTransaction<br>
into that JNDO name. (In some JTA implementations the UserTransaction and<br>
TransactionManager have the same interfaces). And to make Drools Persistence<br>
JPA works, you should put 4 or 5 objects into env, they are:<br>
<br>
</div></div><div class="im">env.set(EnvironmentName.ENTITY_MANAGER_FACTORY,<br>
</div><div class="im">this.defaultPersistenceSvc.getSessionFactory());<br>
env.set(EnvironmentName.APP_SCOPED_ENTITY_MANAGER,<br>
this.defaultPersistenceSvc.getCurrentSession()); // If you don't handle the<br>
EntityManager your self, you can omit this line.<br>
</div><div class="im">env.set(EnvironmentName.TRANSACTION_MANAGER,<br>
</div><div><div></div><div class="h5">this.txSvc.getTransactionManager()); // java:comp/env/TransactionManager<br>
env.set(EnvironmentName.TRANSACTION, this.txSvc.getTransaction()); //<br>
java:comp/UserTransaction<br>
env.set(EnvironmentName.TRANSACTION_SYNCHRONIZATION_REGISTRY,<br>
this.txSvc.getTransactionSynchronizationRegistry()); //<br>
java:comp/env/TransactionSynchronizationRegistry<br>
<br>
all the methods called from txSvc fetch objects from according JNDI. In my<br>
application all these JNDI objects are config-ed via Tomcat like this (in<br>
META-INF/context.xml):<br>
<br>
<Resource name="jdbc/defaultDS" auth="Container"<br>
type="javax.sql.XADataSource"<br>
factory="bitronix.tm.resource.ResourceObjectFactory"<br>
uniqueName="jdbc/defaultDS" /><br>
<br>
<Resource name="jdbc/droolsTaskDS" auth="Container"<br>
type="javax.sql.XADataSource"<br>
factory="bitronix.tm.resource.ResourceObjectFactory"<br>
uniqueName="jdbc/droolsTaskDS" /><br>
<br>
<Resource name="TransactionManager" auth="Container"<br>
type="javax.transaction.TransactionManager"<br>
factory="bitronix.tm.BitronixTransactionManagerObjectFactory" /><br>
<br>
<Resource name="TransactionSynchronizationRegistry" auth="Container"<br>
type="javax.transaction.TransactionSynchronizationRegistry"<br>
<br>
