[jboss-user] [JBoss jBPM] - hibernate AnnotationConfiguration rather than Configuration

I am trying to persist an annotated @Entity object but I do not have a mapping resource foo.hbm.xml.
If HibernateHelper.java returned an AnnotationConfiguration rather than
a Configuration It would seem I could then specify a property in hibernate.cfg.xml such as

  | <mapping package="foo"/>
  | <mapping class="foo.MyAnnotatedFooClass"/>
Which then would allow my annotated class to be stored using a HibernateLongInstance
rather than as a blob (since my annotated class is Serializable)
So Then I put this at the top of jbpm.varmapping.xml (which I havent seen as example but seems to work...except for the resulting exception).

  |     <jbpm-type>
  |       <matcher>
  |         <bean class="org.jbpm.context.exe.matcher.ClassNameMatcher">
  |           <field name="className"><string value="foo.MyAnnotatedFooClass" /></field>
  |         </bean>
  |       </matcher>
  |       <variable-instance class="org.jbpm.context.exe.variableinstance.HibernateLongInstance" />
  |     </jbpm-type>

  | Interesting here is the use of AnnotationConfiguration. The packages and annotated classes are declared in your regular XML configuration file (usually hibernate.cfg.xml). 
  | Note that you can mix the hbm.xml use and the new annotation one. 
  | The resource element can be either an hbm file or an EJB3 XML deployment descriptor. The distinction is transparent for your configuration process.
Exception received when I try this strategy

  | javax.ejb.EJBException: org.hibernate.MappingException: An AnnotationConfiguration instance is required to use <mapping package="foo.MyAnnotatedFooClass"/>
