            </datasources>



The code lists the objects is as follows:
Code:
package br.jrm.academico.curso;


import java.util.List;

import javax.inject.Inject;
import javax.persistence.EntityManager;

import br.jrm.pojo.curso.NivelCurso;

public class NivelCursoEntityController {
   
    @Inject
    private EntityManager entityManager;
   
    @SuppressWarnings("unchecked")
   public List<NivelCurso> listarNiveisCurso(){
       return entityManager.createQuery(" FROM NivelCurso ORDER BY nome ").getResultList();
    }
}



Thanks for the help.
