request.getRequestDispatcher is not working and shows no errors

Question

I have a problem in request.getRequestDispatcher("Valida.jsp"). forward(request, Response); from my non-forward Folder to the Valida.js page. I need to go from an HTML to a javascript (by Ajax) that passes the Infos to a Servlet and this Servlet saves the data in a Javabeans and foward to a jsp to show the data. No console or build error. It simply sits on the main html page.

My Servlet is like this:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    Beans beans = new Beans();
    String email = request.getParameter("email");
    String senha = request.getParameter("senha"); 
    String Pnome= request.getParameter("Pnome");
    String Mnome= request.getParameter("Mnome");
    String Snome= request.getParameter("Snome");

    beans.setEmail(email);
    beans.setSenha(senha);
    beans.setPnome(Pnome);
    beans.setMnome(Mnome);
    beans.setSnome(Snome);

    request.setAttribute("beans", beans);
    request.getRequestDispatcher("Valida.jsp").forward(request, response);
    System.out.println("passou do forward");
}

My JAVASCRIPT

count = 0;
onload = inicia;

function inicia() {

  document.getElementById("idCadastra").addEventListener("click", conecta, false);
}

function conecta() {

  var email = document.getElementById("idEmail").value;
  var senha = document.getElementById("idSenha").value;
  var Pnome = document.getElementById("idPrimeiroNome").value;
  var Mnome = document.getElementById("idNomeDoMeio").value;
  var Snome = document.getElementById("idSobreNome").value;

  if (email != "" && senha != "" && Pnome != "" && Snome != "") {
    console.log("entrou na conexão")
    httpRequest = createRequest();
    httpRequest.open("GET", "Servlet?email=" + email + "&senha=" + senha + "&Pnome=" + Pnome + "&Mnome=" + Mnome + "&Snome=" + Snome, true);
    httpRequest.onreadystatechange = function() {
      if (httpRequest.readyState == 4) {
        if (httpRequest.status == 200) {

        }
      }
    }
    httpRequest.send(null);
  }

}
