presistence.xml with j2se

[tibocu]

Hi,

I run a j2se application with jax.persistence, but I cannot get the EntityManagerFactory declared in the persistence.xml file.

My code:
factory = Persistence.createEntityManagerFactory("em");

I get: No Persistence provider for EntityManager named em

The persistence.xml file is located in src/META-INF/persistence.xml

The application is compiled in the classes directory, with the META-INF/persistence.xml copied.

The application is not packaed in a jar.

Shoudl works ?

Tks

Maybe you have not declared the name of your persistence unit in your persistence.xml file:

<persistence>
 <persistence-unit name="em">
 <jta-data-source>java:/DefaultDS</jta-data-source>
 [...]
 </persistence-unit>
</persistence>
