Hello,

I want to deploy JBPM in production using persistence of processes and human tasks in an Oracle database. I have changed in  the persistence.xml and hiberante.cfg.xml file the H2 database connection configuration  by Oracle configuration. 
We encounter the  following exceptions  while listing Processes in the jbpm-console :

Caused by: javax.persistence.PersistenceException: [PersistenceUnit: org.drools.persistence.jpa] Unable to build EntityManagerFactory
...
Caused by: org.hibernate.HibernateException: The chosen transaction strategy requires access to the JTA TransactionManager
What is the jar involved ?

The JBPM 5 involved a lot of components. For production use, we want a minimal deployment at first time.
We want to cut dependency with a drools-guvnor repository,  and obtain the processes definition from file system. 

How can we achieve that ?
Can we change only the ChangeSet.xml in jbpm-gwt-core-5.0.0.jar ?

Thanks in advance,
