public interface DAO<E> {

CategoriaDAO.java

@Stateless
public class CategoriaDao implements DAO<Categoria> {

Interface Servico.java

@Local
public interface Servico<E> {

CategoriaService.java

@Stateless
public class CategoriaService implements Servico<Categoria> {

    @EJB
    private CategoriaDao categoriaDao;

CategoriaController.java

@WebServlet("/categoria")
public class CategoriaController extends HttpServlet {
    private static final long serialVersionUID = 1L;

    @EJB
    private CategoriaService categoriaService;
