Eclipse RCP + EclipseLink

[hazzad hazzad]

Hi,

I try to use Eclipse RCP together with EclipseLink. I also followed
the tutorial at http://www.vogella.de/articles/JavaPersistenceAPI/article.html.
It's really no deal to create an java class with a main using
Eclipselink and run it as application. But as soon as I try to do this
under RCP in a view - just used the plain sample application with a
view example - I end up in:

javax.persistence.PersistenceException: No Persistence provider for
EntityManager named.....

What ever I import or do, the result is more or less the same. So far
I think it has something to do with the class loader under rcp, but my
knowledge is not good enough to verify that. I would appreciate if one
could extend the above tutorial for an simple eclipse rcp application
with a plain view.

My code always blows up when I try to create the EntityManagerFactory
instance at :

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

The identical code works for an java class with a main, running as
application...?

Many Thanks.
