[jboss-user] [JBoss jBPM] - EJB-JBPM: transaction clash (rollbacks)

[Johan.Parent]

Hi all,

I'm in desperate need for some pointers. I try to introduce jbpm (3.1.4) into an existing EJB2.X app. The jbpm code is wrapped in the thoroughly tested session bean, works. When the 2 are put together things collide. Monitoring of the db queries indicates that the business logic and jbpm are doing there work. BUT all the work is finally undone by a rollback on the db connection.

Unfortunately I can't cut&paste the logged data here. But in a nutshell: the app does a few selects then call the jbpm code to start a process. Nothing more. Any, really ANY, pointer would be welcome.

Best regards,

Johan 

The setting: 
- weblogic 8.1 
- sybase
- jbpm 3.1.4
- both apps use the same datasource
- DbPersistenceServiceFactory:

  | <field name="isTransactionEnabled"><false /></field>
  | 
- hibernate settings:

  |       <property name="dialect">org.hibernate.dialect.SybaseDialect</property>
  |     <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
  |     <property name="hibernate.connection.datasource">tx_sybase</property>
  |     <property     name="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
  |       <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.WeblogicTransactionManagerLookup</property>
