WELD-001408 Unfulfilled dependencies when entering EntityManager

I have a @Statelessbean that implements two interfaces (remote and local). I also added an announcement @LocalBeanfor access to a bean with a view without an interface.

@Stateless
@LocalBean
public class WeatherDataBean implements WeatherDataBeanRemote, WeatherDataBeanLocal {
    @Inject
    private EntityManager entityManager;

    public WeatherDataBean () {

    }
    // ....attributes, getter & setter methods ....
}

I use @Injectfor this reason from this J8SS AS7 quick start example :

We use the Resource Maker pattern from CDI to the alias of the old-fashioned entity manager @PersistenceContext injection to the CDI style injection. This allows you to use a consistent embedding style (@Inject) throughout the application.

Now previously I used:

@PersistenceContext(unitName="WeatherStationJPA")
private EntityManager entityManager;

In EJB and it works without any problems. But with annotation, @InjectI get this error:

WELD-001408 [EntityManager] [@Default] [[field] @Inject private ejb.WeatherDataBean.entityManager]

:

public class Resources {
     @SuppressWarnings("unused")
     @PersistenceContext(unitName="WeatherStationJPA")
     @Produces
     private EntityManager entityManager;

     @Produces
     FacesContext getFacesContext() {
         return FacesContext.getCurrentInstance();
     }
}

, ?

EDIT: @LightGuard , , :

  • WeatherDataBean :

    import javax.ejb.LocalBean;
import javax.ejb.Stateless;

  • :
