Harald Wellmann commented on DELTASPIKE-420:
--------------------------------------------
I can't get this to work in WildFly 8.2.0. I've tried various combinations of
TransactionStrategies and Transactional annotations (DeltaSpike vs. JTA), and
there is always some situation that fails.
My use cases:
{code}
@Repository
@Dependent
// add suitable transaction annotation here
@EntityManagerConfig(entityManagerResolver = CoreEntityManagerResolver.class)
public abstract class FooDao extends AbstractEntityRepository<Foo, Long>
{code}
I'm injecting this DAO into
1) stateless session beans
2) singleton startup beans
3) plain old non-transactional CDI beans
I'm invoking methods of the injected DAO from each of these 3 types of classes.
In cases 1) and 2), DAO methods should join the transaction of the calling EJB.
In case 3), each DAO method invocation should automagically be wrapped by a new
JTA transaction.
I'm not sure if this is a configuration issue or a bug in the
{{TransactionStategy}} implementations provided by DeltaSpike. I'd expect the
{{EnvironmentAwareTransactionStrategy}} to cover this situation, but I'm
getting an exception saying the my singleton startup bean must not access
{{UserTransaction}}.

> It's nice to get semi-automatic repositories from DeltaSpike Data, but these
> repositories would be even more fun if they were transactional, not
> necessarily by default, but at least by simple configuration.
> Possible approaches:
> 1) Add @Transactional to an abstract repository class, i.e.
> javax.transaction.Transactional in Java EE 7, or
> org.apache.deltaspike.jpa.api.transaction.Transactional otherwise.
> Currently, this does not work due to DELTASPIKE-419.
> 2) Make it easy to override the @Repository binding or the query handler, to
> add transactional behaviour.
