hi all,

I want to call the jbpm CommandServiceBean in a UserTransaction. But the problem is, jBPM doesn't optain the transaction. So the database values has been changed before the commit.

Here's the code

UserTransaction transaction = sessionContext.getUserTransaction();
transaction.begin();
//JNDI look up the get CommandServiceBean
// creation of an Command, to create new process instance and start it.
commandService.execute(command);
transaction.commit;

The jbpm.cfg.xml I use.

...
 <jbpm-context>
 <service name="persistence">
 <factory>
 <bean class="org.jbpm.persistence.jta.JtaDbPersistenceServiceFactory">
 <field name="isTransactionEnabled"><false /></field>
 </bean>
 </factory>
 </service>
 ...
 </jbpm-context>
...

And the hibernate.cfg.xml

<!-- JTA transaction properties (begin) -->
 <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
 <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
 <!-- JTA transaction properties (end) -->

I have to admit that I can see the changes in the jbpm database not until the transaction commits. But the changes on the database i call during the workflow are directly persistent.

How can configure jbpm?

Thanks in advance.
