Hello everybody,

I need an application-managed EntityManagerFactory, because I have to control the transactions manually.

So I create the EntityManagerFactory via

EntityManagerFactory emf = Persistence.createEntityManagerFactory("wfmsem");

but I get the following exception:

javax.persistence.PersistenceException: No Persistence provider for EntityManager named wfmsem
 at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:41)

my persistence.xml looks like:

<persistence>
 <persistence-unit name="wfmsem" transaction-type="RESOURCE_LOCAL">

 </persistence-unit>
</persistence>

What is wrong? I use jboss version 4.0.3SP1


Thans in advance!

Regards,
Arthur
