There's certainly nothing wrong with that approach.
However, the situation is not as simple as it seems. When
used in a
JTA
environment, by default an EntityManager will use a transactional
persistence context. This means that each transaction essentially
automatically gets a new
The spec defines that the way to get
application-managed EMs is via a call to
Persistence.createEntityManager(). Container-managed EMs come from
PersistenceProvider.createContainerEntityManager() (or
something like
that).
App managed em suck because you can't use JTA transactions.
1. You must use a new EntityManager for each test.
2. If you have the DataCache enabled, you'll have to clear it. You
can do that through:
((OpenJPAEntityManagerFactory) emf).getStoreCache().evictAll();
3. There is no way to clear the cache on cluster node B from cluster
node A; you have
Why not add a way to clear the cluster cache?
Any developer is free to do so.
