DAO not injecting with @EJB annotation

I am making a request for "/ counter / {id}" by PostMan and when the code arrives at notificationAdobe.controller (id) , I get the error message saying notification is null .

PS: I'm using Wildfly 11 with Eclipse Oxygen

Controller

import javax.ejb.EJB;
import javax.ejb.LocalBean;
import javax.enterprise.context.RequestScoped;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;

@Path("ejb/notificacao")
@Stateless
@LocalBean
public class NotificacaoControladorEJB {


    SmartJava smartjava = new SmartJava();
    @EJB
    NotificacaoDAOEJB notificacaoDAO;


    @GET
    @Produces("application/json; charset=UTF-8")
    @Path("/contador/{id}")
    public Notificacao contadorGet(@PathParam("id") int id) {
        long quantidade;
        try {
            quantidade = notificacaoDAO.contador(id);

            return new Notificacao(quantidade);
        } catch(Exception e) {
            quantidade = 0;
            System.err.println(smartjava.getFullStackTrace(e));

            return new Notificacao(quantidade);
        }
    }
