Hi Christian!
We might need to tweak the docs a bit. using @PersistenceContext for injecting
an EM will give you a 'container managed EM' if you run that code in an EE
server like WS8, JBossAS, etc. Those EMs _only_ work together with EJBs.
If you need JTA then you can use a PersistenceContextType.EXTENDED
EntiryManager and a UserTransaction. Our @TransactionScoped is able to handle
that.
If you just have a single database and don't like to use JTA, then you can
simply create the EM yourself inside the producer [1]. Please note that you
need to add the 'resource-local' to your persistence.xml if you like to be 100%
spec conform:
<persistence-unit name="yourunit" transaction-type="RESOURCE_LOCAL">...
In our real world application we have an own EntityManagerFactoryProducer which
not only creates the EntityManagerFactory but also acts as a central point for
all the configuration.
The extended persistence context will do it hopefully. But by the way,
if I use TransactionScoped for an entity manager and try to use that
entity manager in a method that does not use @Transactional I get an
error that the context is not active, is that expected?

Subject: JPA Module Problem with Websphere 8
Hey guys!
I tried to use the JPA Module today within Websphere 8 and faced a problem.
I have a class that produces an entity manager as described in the documentation
and I am using the transaction scope like the following:
@PersistenceContext(
unitName = "ClevercureNew")
private EntityManager em;
@Produces
@TransactionScoped
protected EntityManager createEntityManager(){
return em;
}
protected void closeEntityManager(@Disposes EntityManager em){
if(em.isOpen()){
em.close();
}
}
When I start the application I fire a CDI Event to some observers, that my
application has been started. Some of these observers use JPA to persist some
things and therefore I use the Transactional interceptor. Unfortunately I
receive an error from the transactional interceptor:

Besides this error at application startup, I can see that the resource local
transaction strategy is used as default. Shouldn't the default be the
environment aware strategy or have I missed to configure something?
The last problem occurs at the "normal" usage scenario where I just
try to query something with the entity manager.

Can anyone help me with that please?
