JAVA - Ajuda em Paginação

Caros amigos, saudações.

Estou escrevendo um Sistema em JAVA Web e estou encontrando um problema para fazer Paginação.

O sistema informa o Limite de registro por página, mas não mostra abaixo da tabela a paginação.

Alguém pode me ajudar ?

Posto o Código abaixo.

Controller - Servlet

package br.com.rc.controlador;

import br.com.rc.modelo.Cargo;
import br.com.rc.modelo.dao.CargoDAO;
import java.io.IOException;
import java.util.List;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
* Servlet
*/
public class srvCargos extends HttpServlet {

 private CargoDAO crgDao = new CargoDAO();

 private final String pagListar = "/views/cargos/cargos.jsp";
 private final String pagNovo = "/views/cargos/cargoNovo.jsp";
 private final String pagEditar = "/views/cargos/cargoEditar.jsp";

 protected void processRequest(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html;charset=UTF-8");

 String accion = request.getParameter("accion");

 switch (accion) {
 case "listarCargos":
 listarCargos(request, response);
 break;
 default:
 throw new AssertionError();
 }
 }

 protected void listarCargos(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html;charset=UTF-8");

 int paginaActual = 1;
 int registrosPorPagina = 5; // Qtde por Tabela

 if (request.getParameter(pagListar) != null) {
 paginaActual = Integer.parseInt(request.getParameter(pagListar));
 }

 int offset = (paginaActual - 1) * registrosPorPagina;

 List<Cargo> lista = crgDao.ListarTodos(offset, registrosPorPagina);
 int totalRegistros = crgDao.contarTotal();
 int totalPaginas = (int) Math.ceil((double) totalRegistros / registrosPorPagina);

 request.setAttribute("cargos", lista);
 request.setAttribute("totalPaginas", totalPaginas);
 request.setAttribute("paginaAtual", paginaActual);

 request.getRequestDispatcher(pagListar).forward(request, response);

 }

 @Override
 protected void doGet(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }

 @Override
 protected void doPost(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }

 @Override
 public String getServletInfo() {
 return "Short description";
 }// </editor-fold>

}

	 

	Classe DAO

	 

package br.com.rc.modelo.dao;

import br.com.rc.config.Conexion;
import br.com.rc.modelo.Cargo;
import java.sql.*;
import java.util.ArrayList;
import java.util.List;

/**

*/
public class CargoDAO {

 private Connection cn = null;
 private PreparedStatement ps = null;
 private ResultSet rs = null;

 private int noOfRecords;

 public ArrayList<Cargo> ListarTodos(int offset, int noOfRecords) {
 ArrayList<Cargo> lista = new ArrayList<>();
 try {
 cn = Conexion.getConnection();
 String sql = "select * from Cargo ORDER BY nombreCargo ASC limit " + offset + ", " + noOfRecords;

 ps = cn.prepareStatement(sql);
 rs = ps.executeQuery();

 while (rs.next()) {
 Cargo obj = new Cargo();
 obj.setIdCargo(rs.getInt("idCargo"));
 obj.setNombreCargo(rs.getString("nombreCargo"));
 obj.setEstado(rs.getBoolean("estado"));
 lista.add(obj);
 }
 } catch (Exception ex) {
 ex.printStackTrace();
 } finally {
 try {
 if (cn != null) {
 cn.close();
 }
 if (rs != null) {
 rs.close();
 }
 if (ps != null) {
 ps.close();
 }
 } catch (Exception ex) {

 }
 }
 return lista;
 }

 public int contarTotal() {
 String sql = "Select Count(*) From Cargo";
 try (PreparedStatement ps = cn.prepareStatement(sql)) {
 ResultSet rs = ps.executeQuery();
 if (rs.next()) return rs.getInt(1);
 } catch (SQLException e) { e.printStackTrace(); }
 return 0;
 }

 public int getNoOfRecords() {
 return noOfRecords;
 }
