Hello Mauricio,
About jpa1, I should make an error,but I say you use jpa1 because of the file : jbpm-services\jbpm-human-task-services\src\main\resources\META-INF\Taskorm.xml
wich start with :
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm orm_1_0.xsd"
version="1.0">
And the file jbpm-services\jbpm-human-task-services\src\test\resources\META-INF\persistence.xml
<persistence version="1.0"
xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:orm="http://java.sun.com/xml/ns/persistence/orm"
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 http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd">
About the persistence units :
I can't have a unique persistence unit, if human task persistence is manage inside my application. Indeed, I have a lot of mapping objects dedicated to the application that are saved in a database. And I have another database dedicated to jbpm mapping. I don't know for the moment how I will do that without the web service.
Regards,
