access DeltaSpike Data repository as EJB
Need to move my JPA and DeltaSpike repositories to EJB EAR module to allow
access from two different WARs in the same EAR
What is recommnded approach to access DeltaSpike repository as EJB ?
For adhoc I created PersonService class annotated with @Stateless
@Stateless
public class PersonService {
@Inject PersonRepository personRepository;
public PersonRepository getRepository(){
return personRepository;
}
}
Do you have some other ideas ?

Agreed. If you need transactions, you should be able to use our
@Transactional interceptor. If you're trying to use a distributed
architecture using remote EJBs, I would recommend putting facades in front,
but maybe ideally expose a REST API instead?

Hi Paweł,
just a 'dumb' question: does it needs to be an EJB? this information you
need can't be exposed as a REST service? I'm saying that because I've been
there and migrate lots of ears to wars and ejb modules to rest
service...maybe it apples for your case too.

Hi John,
It works as you said. I don't know how since it is in separate EJB module
but it works :)
Just in case if the JPA / DeltaSpike module is in separate Server/JVM then
how to access the repositories as EJB ?
best regards

Temat: Re: access DeltaSpike Data repository as EJB
Hi Pawel,
Creating them as EJBs shouldn't be required. They're still CDI beans. In
the JAR that you expose, make sure the various deltaspike extensions are
activated in your javax.enterprise.inject.spi.Extension file. Make sure
you have a valid beans.xml to discover all beans.
At a minimum you need the repository extension and bean provider. You
should then be able to inject them. Please do post back if this gives you
some trouble, happy to help.

Hi Pawel,
Creating them as EJBs shouldn't be required. They're still CDI beans. In
the JAR that you expose, make sure the various deltaspike extensions are
activated in your javax.enterprise.inject.spi.Extension file. Make sure
you have a valid beans.xml to discover all beans.
At a minimum you need the repository extension and bean provider. You
should then be able to inject them. Please do post back if this gives you
some trouble, happy to help.
