InvalidStateException
I get this message when trying to persist an Entity:
Exception in thread "AWT-EventQueue-0" <openjpa-1.0.1-r420667:592145 nonfatal user error> org.apache.openjpa.persistence.InvalidStateException: Can only perform operation while a transaction is active.
What does it mean?

I don't know what is inside "getEntityManager()" but the error suggests to
me that it might be returning a different entity manager instance at each
call, and hence you are committing outside a transaction which is what this
error is telling you.
I would code it like this:
EntityManager em = getEntityManager();
em.getTransaction().begin();
em.persist(legalEntity);
em.getTransaction().commit();

FWIW, Chris seems to have performance issues instantiating EMs, but I don't.

RE: InvalidStateException
Posted by C N Davies <cn...@cndavies.com>.
I keep is simple by implementing an EntityService and let it handle the
errors and such, so I can standardise error handling, persisting or merging
decisions etc. Then I just have a private static instance of the factory so
it gets shared application wide. Also for perfomance purposes I keep a cach
of entity managers so I don't have to continually instantiate new ones
because of the performance hit of doing so.

Thanks Chris, now I see the problem.
So my approach is not correct!
Should it be:
EntityManagerFactory -- ServletContext[by a filter or listener]
EntityManager -- page [by request or session]
Can anyone point me the right direction on the ServletContext[by a filter or
listener] implementation example?
Thanks again,

You are creating a new entity manager each time you retrieve an entity
manager, hence you will never have a transaction. Use my sample code and it
will work.

my guess is that it means you haven't started a transaction yet.
