Hello,

I want to do Xa transaction with jBPM and another Datasource of my application. Both cases, I am using only Hibernate, no spring.

I started with UserTransaction, then started normal hibernate operation, here DS for Normal Hibertane is XA and JTA is the transaction mode and I am using Weblogic 10 AS.  

Now my normal Hibernate transaction using JTA is working fine, but jBPM part is not working fine, I can commit both the DS together, but if there is any exception in my Normal DS, jBPM still commits which is WRONG. I stringly believe I made a mistake somewhere in jBPM configuration. Can anyone tell me where am I wrong?

Here is my code base :-

jbpm.cfg.xml









<
jbpm-configuration>

<!--The default configurations can be found in org/jbpm/default.jbpm.cfg.xml
Those configurations can be overwritten by putting this file called
jbpm.cfg.xml on the root of the classpath and put in the customized values.
-->


<jbpm-context>
<service name="persistence">
<factory>
<bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
<field name="isTransactionEnabled"><false /></field>
<field name="isCurrentSessionEnabled"><true /></field>
<field name="sessionFactoryJndiName">
<string value="java:/myHibSessFactJndiName" />
</field>
<!--<field name="sessionFactoryJndiName">java:/myHibSessFactJndiName</field>-->
</bean>
</factory>
</service>
</jbpm-context>
<string name="resource.hibernate.cfg.xml" value="hibernate.cfg.xml" /></jbpm-configuration>
