Servlet: 

@WebServlet("/AdicionaContato")
public class AdicionaContatoServlet extends HttpServlet {
    @Override
    protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        //busca o writter
        PrintWriter out = response.getWriter();

        //busca parametros
        String nome = request.getParameter("nome");
        String endereco = request.getParameter("endereco");
        String email = request.getParameter("email");
        String dataEmTexto = request.getParameter("DataNascimento");

        //Converter data
        Calendar dataNascimento = null;
        try {
            Date date = new SimpleDateFormat("dd/MM/yyyy").parse(dataEmTexto);
            dataNascimento = Calendar.getInstance();
            dataNascimento.setTime(date);
        } catch (ParseException e){
            out.println("Erro na conversão da data");
            return;
        }
    }
}

After using SimpleDataFormat and set date with getInstance / setTime was not it to be populated?

My HTML page that makes subbmit 

<!DOCTYPE html>
<html>

The% of the input of the date of birth is different from the name used in name .

One looks like this: getParameter(String) , and the other is like this: dataNascimento DataNascimento is Case Sensitive .

Make sure this is not the cause of the problem.

Make a regex to remove characters Difference between "iostream" or "stdlib.h stdio.h" in #include
