in the enterprise.ear, the configurations are packaged in a separate jar file called jbpm-configs.jar these are the relevant properties in the hibernate.cfg.xml <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property> | <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property> | <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property> | <property name="hibernate.connection.datasource">java:/JbpmDS</property> | <property name="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property> | <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property> | and this is the jbpm.cfg.xml part of the persistence/tx configs <service name="persistence"> | <factory> | <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory"> | <field name="isCurrentSessionEnabled"> | <true /> | </field> | <field name="isTransactionEnabled"> | <false /> | </field> | </bean> | </factory> | </service> | if you change to JTA, you might need to set the isTransactionEnabled property to true. i don't know these configs at all. i'll check the docs and get back if i find anything there.
