Hello Mauricio,

I have install jbpm-human-task-services and jbpm-human-task-workitems.
And finally change to a persistence.xml as yours :

</persistence>


But the application fail to deploy with this error :

I have this message for each EntityManager wich is Inject.
In my application I use :
protected @PersistenceContext(unitName="org.jbpm.task") EntityManager em;

and I have no error. 

Do you no if it is a dependency problem, or what I can do for this please?

Regards,
