This is my default servlet. Code:
@WebServlet(value="/")
public class DefaultServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String contextPath = request.getContextPath();
response.sendRedirect(contextPath+"/login.jsp");
}
}login.jsp locates in WebContent.
login.jsp code :
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<body>

<form action="login" method="post" onsubmit="return checkForm();">

</form>

</body>
</html>var username_empty = "<span style='COLOR:#ff0000'><font size='2px'> × name in null！</font></span>";
var password_empty = "<span style='COLOR:#ff0000'><font size='2px'> × pass is null！</font></span>";
var info_right = "<span style='COLOR:#006600'><font size='2px'> √ </font></span>";
var pass_error = "<span style='COLOR:#ff0000'><font size='2px'> × </font></span>";
window.onload = function() {
document.getElementById("userName").focus();
};
/**
*
*
* @param {}
* target
* @param {}
* Infos
*/
function showInfo(target, Infos) {
document.getElementById(target).innerHTML = Infos;
}
/**
* check form
*
* @return {Boolean}
*/
function checkForm() {
var userName = document.getElementById("userName").value;
var userPass = document.getElementById('userPass').value;
if (userName == null || userName == "") {
showInfo("userName_notice", username_empty);
document.getElementById("userName").focus();
return false;
}else{
showInfo("userName_notice", info_right);
}
if (userPass == null || userPass == "") {
showInfo("userPass_notice", password_empty);
document.getElementById("userPass").focus();
return false;
}else{
showInfo("userPass_notice", info_right);
}
return true;
}But when I access the login.jsp,check.js 302 is found.JavaScript doesn't work. What should I do to solve this problem ? Any suggestion will be appreciated.
