I am trying to validate the login and password of the user, in that if not enter the login fields and password will appear a message in the screen "Please fill in the fields of login or password" or if the user type the wrong username or password will appear an "Incorrect Login or Password" screen message but it does not show the messages.
Why does not it show the message on the jsp page?

Instead of validating HTML Form Using Controller/Servlet You Can use 'REQUIRED' tag in html as follow.
Login:<input type="text" id="login" name="login" Required><br/><br/>
Senha:<input type="text" id="senha" name="senha" Required><br/>
And Displaying message on JSP from servlet use below code
for Servlet
if(login_validacao.getLogin()==null && login_validacao.getSenha()==null)
{
response.sendRedirect("login.jsp?vazio=" + URLEncoder.encode(vazio, "UTF-8"));
}
else if(login_validacao.getLogin().equals(request.getParameter("login"))
& login_validacao.getSenha().equals((request.getParameter("senha"))))
{
RequestDispatcher rd=request.getRequestDispatcher("/index.jsp");
rd.forward(request, response);
}
else
{
response.sendRedirect("login.jsp?incorretos=" + URLEncoder.encode(incorretos, "UTF-8"));
}
FOR JSP
<c:if test="${!empty vazio}">
<p style="color:red;" align="center">${param.vazio}</p>

Is there any way that I can do it this way and if so is there a solution to the error I have?
I think you do not want the http:// in there, for a proper URL you would want either MySQL:// -OR- http:// not both.
I am guessing your proper string is going to be :
jdbc:mysql://danu6.it.nuigalway.ie:3306/mydb1899/players
jdbc:sqlserver://[serverName[\instanceName][:portNumber]][;property=value[;property=value]]
That is the format for connection URLs. Does yours work with that?

You only seem to have one handler mapping, and it's POST. Add another handler mapping for the same url path with GET. Consider the "POST Redirect GET" pattern as well.
In my web application, I have a home page where the options available to the user are placed in a fixed sidebar in the top of the screen, and each one of this options are opened inside of a tag <div> in this same page.
My problem is: when this content is a form, and I submit it to the server, after the processing, the output page isn't opened in this <div>, but in the entire navigation space. What I want is a way of capture this return and display it in the same <div> it was originated.
the code for my home page is:

I am using Spring, and the pages linked here are handled by Controller. By example,the page "cadastra_evento.html" is:
<%# page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Lista de Eventos</title>
<link href="css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<div class="alert alert-info">
<strong>Eventos</strong> Segue a lista de eventos cadastrados.
</div>
<div class="container">
<div class="row">
<div class="col-md-3">Nome</div>
<div class="col-md-3">Descrição</div>
<div class="col-md-3">Periodo</div>
<div class="col-md-3">Duração</div>
</div>
<c:forEach var="item" items="${lista}">
<div class="row">
<div class="col-md-3"><c:out value="${item.nome}"/></div>
<div class="col-md-3"><c:out value="${item.descricao}"/></div>
<div class="col-md-3"><c:out value="${item.data_inicial}"/> - <c:out value="${item.data_final}"/></div>
<div class="col-md-3"><c:out value="${item.duracao}"/></div>
</div>
</c:forEach>
</div>
<div class="alert alert-info">
<strong>Novo</strong> Cadastre um novo evento.
</div>
<form method="post" action="cad_evento.html">
<input type="text" name="nome" placeholder="Nome" size=20 maxlength=40> <br/>
<input type="text" name="descricao" placeholder="Descrição" size=30 maxlength=100> <br/>
<h3>Periodo da Data</h3>
inicio: <input name="data_inicial" placeholder="DD-MM-AAAA" required pattern="\d{2}-\d{2}-\d{4}" /> <br/>
final: <input name="data_final" placeholder="DD-MM-AAAA" required pattern="\d{2}-\d{2}-\d{4}" /> <br/>
<h3>Periodo do Horário</h3>
inicio: <input name="hora_inicial" placeholder="HH:MM:SS" required pattern="\d{2}:\d{2}:\d{2}" /> <br/>
final: <input name="hora_final" placeholder="HH:MM:SS" required pattern="\d{2}:\d{2}:\d{2}" /> <br/>
<input type="text" name="duracao" placeholder="duração" size=20 maxlength=2> <br/>
<button type="submit" class="btn btn-lg btn-primary">Cadastrar</button>
</form>
</body>
</html>
To finish, the page "cad_evento.html" used as action for the form above, is handled by method of same name from Controller:
#RequestMapping(value="/cad_evento", method=RequestMethod.POST)
public ModelAndView cadastra_evento(#RequestParam("nome") String nome, #RequestParam("descricao") String descricao, #RequestParam("data_inicial") String data_inicial, #RequestParam("hora_inicial") String hora_inicial, #RequestParam("data_final") String data_final, #RequestParam("hora_final") String hora_final, #RequestParam("duracao") int duracao) {
if(sessao != null)
{
if(sessao.getUsuario().temAutorizacao("cad_evento"))
{
Date d_inicio = new Date(Date.parse(data_inicial));
Date d_final = new Date(Date.parse(data_final));
Time h_inicio = new Time(Time.parse(hora_inicial));
Time h_final = new Time(Time.parse(hora_final));
EventoDAO evento = new EventoDAO(nome, descricao, d_inicio, d_final, h_inicio, h_final, duracao, sessao.getUsuario());
int saida = evento.cadastra();
if(saida == 0)
{
ModelAndView mav = new ModelAndView();
mav.addObject("message", "Erro ao cadastrar o evento");
return mav;
}
else
{
ModelAndView mav = new ModelAndView();
mav.setViewName("/listagem_evento");
return mav;
}
}
else
{
ModelAndView mav = new ModelAndView();
mav.addObject("message", "Usuário sem permissão de acesso");
return mav;
}
}
else
{
ModelAndView mav = new ModelAndView();
mav.setViewName("/usuario_login_page");
return mav;
}
}
Someone have any thoughts about how to do that?
Well, spring mvc just open new page with a content you set in ModelAndView. If you want to load somthing just in some part of page ( in this case ) there pure javascript / jquery ajax is needed. So steps needed here:
Add javascript which will do ajax request to controller
Controller need to return JSON ( #ResponseBody can help you )
You have to do some DOM manipulation using javascript/jquery to put JSON answer to your div.
