I would like to use OpenEJB in the jUnit tests of a maven based

I am using OpenJPA for my JPA implementation.
One thing to verify is that you've filled in the "unitName" attribute
of the PersistenceContext annotation and that the unit name matches a
persistence unit declared in a META-INF/persistence.xml in the
application jar.
We do validate several things about your app, but this particular one
is still on the todo list:
http://issues.apache.org/jira/browse/OPENEJB-453
Even still it should result in failure later. Hopefully we can find it.
The unit test logs the OpenEJB startup, ending with "INFO - OpenEJB
Ready.", and I can get the entityManager by creating an
EntityMangerFactory then creating the EntityManager from the factory.
I suspect a configuration error on my part.
Where should I look?
If you're persistence unit was not found when we attempted to resolve
the reference (created via the annotation) during the time the bean
as loading, we'd throw one of these which should be logged and would
fail your app:
throw new IllegalArgumentException("Persistence unit " +
contextInfo.persistenceUnitName + " for persistence-context-ref " +
contextInfo.referenceName + " not found");
If we attempted to find something for injection and it mysteriously
wasn't there, we'd log one of these:
logger.warning("Injection data not found in enc: jndiName='" +
injection.getJndiName() + "', target=" + injection.getTarget() + "/"
+ injection.getName());
If something failed to be injected (missing setter perhaps), we'd log
one of these:
logger.warning("Injection: No such property '" + property + "' in
class " + beanClass.getName());
We do have a rather large example (our test suite) that has injection
of PersistenceContext among other things:

itests-beans/src/main/java/org/apache/openejb/test/stateless/
AnnotatedFieldInjectionStatelessBean.java
http://svn.apache.org/repos/asf/openejb/trunk/openejb3/itests/openejb-
itests-beans/src/main/resources/META-INF/
Definitely let us know even if you find the issue as we really want
everything to be bullet proof. No one should be left scratching
their head even if it is there fault -- that should be one of the
advantages of embedded testing.
