Yes i know that the question of jpa/support was evocated then abandoned for the new 4.x architecture.
I was already disapointed at that time... ;-(

Nonetheless, until 4.3, we were able to inject the underlying hibernate session factory in jbpm classes

In 3.x we used this kind of adaptator:

public class AdaptedJbpmFactoryBean extends LocalJbpmConfigurationFactoryBean {
 @PersistenceContext
 private EntityManager em;
 public void afterPropertiesSet() throws Exception {
  try {
   Session session = (Session) em.getDelegate();
   setSessionFactory(session.getSessionFactory());
   super.afterPropertiesSet();
  } catch (Exception e) {}
 }

In 4.1-2 we rely on:
 
/** */
public class SpringJpaConfiguration extends SpringConfiguration {
 /** */
 @PersistenceContext
 private EntityManager em;
 /** */
 public SpringJpaConfiguration(String jbpmConfigurationLocation) {super(jbpmConfigurationLocation);}
 /** */
 public void initSessionFactory(){
  setHibernateSessionFactory(((Session) em.getDelegate()).getSessionFactory());
 }
 
the classes are loaded and initialized during ApplicationContext loading
Spring transaction management is used,
 
JBPM mapping files are loaded with an added xml persistence unit (jpa)
 
<?
 
xml version=+"1.0"+ encoding=+"UTF-8"+?><
 

persistence version=+"1.0"+ 
xmlns=+"http://java.sun.com/xml/ns/persistence"+ xmlns:xsi=+"http://www.w3.org/2001/XMLSchema-instance"+ 
xsi:schemaLocation=+"http://java.sun.com/xml/ns/persistence+http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
++ 
++>
 
 
 
<!-- ###################### -->
 
<!-- # jbpm mapping files # -->

<persistence-unit name=+"xxxx"+ transaction-type=+"RESOURCE_LOCAL"+>

<mapping-file>jbpm.identity.hbm.xml</mapping-file>
 
 
<exclude-unlisted-classes>true</exclude-unlisted-classes>
 
 
</persistence-unit></
 

persistence> 
 

 

In 4.3, we can't find a way to do something similar in org.jbpm.api.ProcessEngine
jta should be a solution... but we are not working on a full jee stack, 
so we have to make it by hand(?), indeed, if nothing else is found.
