Ola tudo bem? Toda vez que eu tento usar o plugin vraptor-jpa ou mesmo crio um EntityManager Producer ele não funciona, mas já verifiquei umas 500x todas as classes e até fiz rastreamento de bug e mostrou que o EntityManager Está Vindo nulo. Aqui estão alguns códigos: Um exemplo de DAO
package br.com.jamalxvi.dao;
import java.util.Collection;
import java.util.List;
import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.Query;
import br.com.jamalxvi.modelo.Estado;
public class EstadoDAO {
private EntityManager manager;
public EstadoDAO(){
this(null);
}
@Inject
public EstadoDAO(EntityManager manager){
this.manager = manager;
}
public Collection<Estado> listar()
{
Query query = manager.createQuery("Select e from Estado e", Estado.class);
Collection<Estado> estados = query.getResultList();
return estados;
}
