Description

Hello,

I have the following data-module repository:

@Repository
public interface CustomerManagementRepository extends EntityRepository<Customer, BigInteger>
{
  ...
}

This repository is called from a stateless session bean, as follows:

  @Inject
  private CustomerManagementRepository repo;
  
  public List<Customer> findByFirsName(String firstName)
  {
    return repo.findByFirsName(firstName);
  }

The following CDI producer is provided as well:

public class EntityManagerProducer
{
  @PersistenceContext
  private EntityManager em;

  @Produces
  public EntityManager createEntityManager()
  {
    return em;
  }
}

When calling the staeless bean from a JAX-RS service, as follows:

  @EJB
  private CustomerManagementFacade facade;

  @POST
  @Consumes(MediaType.APPLICATION_JSON)
  public Response createCustomer(Customer customer)
  {
    Customer newCustomer = facade.saveAndFlushAndRefresh(customer);
    return Response.created(URI.create("/customers/" + newCustomer.getId())).build();
  }

the following exception is raised:

15:48:14,914 ERROR [org.jboss.as.ejb3.invocation] (default task-1) WFLYEJB0034: EJB Invocation failed on component CustomerManagementFacade for method public fr.simplex_software.customer_management.data.Customer fr.simplex_software.customer_management.facade.CustomerManagementFacade.saveAndFlushAndRefresh(fr.simplex_software.customer_management.data.Customer): javax.ejb.EJBException: org.apache.deltaspike.data.api.QueryInvocationException: Exception calling Repository: [Repository=class fr.simplex_software.customer_management.repository.CustomerManagementRepository$$DSPartialBeanProxy,method=saveAndFlushAndRefresh],exception=class java.lang.IllegalStateException,message=Could not find EntityManager with default qualifier.

What seems to happen is that the CDI producer doesn't get called. Do I do anything wrong here ? Please don't send me links to the documentation 'cause I've read it before posting.

Many thanks in advance,

Nicolas

P.S. I have the following in apache-deltaspike.properties:

globalAlternatives.org.apache.deltaspike.jpa.spi.transaction.TransactionStrategy=org.apache.deltaspike.jpa.impl.transaction.ContainerManagedTransactionStrategy
