Re: Minimalistic JPA in GWT 2.1.0.M3

persistence.xml has <persistence-unit name="Domain">.
I tried @PersistenceContext, @PersistenceUnit and
Persistence.createEntityManagerFactory() without any result.
The problem is it does not matter what I type in persistence.xml,
jetty does not see the file.
I'm doing something fundamentally wrong, I'll try this again tomorrow
with a fresh head.
Thanks for sticking with me!
