I have setup a project using both Jdo and Jpa.
I used Jpa Annotation to Declare my Entity.
Then I setup my TestCases based on LocalTestHelper (from Google App
Engine Documentation).
When I run the test,
a call to makePersistent of Jdo:PersistenceManager is perfectly OK;
a call to persist of Jpa:EntityManager raised an error:
java.lang.IllegalArgumentException: Type
("org.seamoo.persistence.jpa.model.ExampleModel") is not that of an
entity but needs to be for this operation
at
org.datanucleus.jpa.EntityManagerImpl.assertEntity(EntityManagerImpl.java:
888)
at
org.datanucleus.jpa.EntityManagerImpl.persist(EntityManagerImpl.java:
385)
Caused by:
org.datanucleus.exceptions.NoPersistenceInformationException: The
class "org.seamoo.persistence.jpa.model.ExampleModel" is required to
be persistable yet no Meta-Data/Annotations can be found for this
class. Please check that the Meta-Data/annotations is defined in a
valid file location.

How can it be the case?
Below is the link to the source code to the maven projects that
reproduce that problems:
http://seamoo.com/jpa-bug-reproduce.tar.gz
Execute the maven test goal over the parent pom you will notice that
3/4 tests from org.seamoo.persistence.jdo.JdoGenericDAOImplTest
passed, while all tests from
org.seamoo.persistence.jpa.JpaGenericDAOImplTest failed.
