Question

I have the following javascript function which i call on the submit button click….

function checkUser()
{
var uname=$(‘#username’).val();
var pword=$(‘#password’).val();
alert(uname);
alert(pword);

      $.getJSON("login.html",{username: uname, password: pword},
              function(message){
   alert(message);
          });
  }

i am using spring mvc 3.0….. Following is the controller that i use…

package com.web.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class LoginController
{
@RequestMapping(“/login.html”)
public @ResponseBody String getLoginStatus(@RequestParam(“username”) String username, @RequestParam(“password”) String password)
{
System.out.println(“\n\nin login controller\n\n”);
if(username==”apoorvabade” & password==”apoorva123″)
{
return “Login successful!!!”;
}
else
{
return “Login failed”;
}
}
}

when i click on the submit button, the function corresponding to the /login.html action is not invoked…. i am using the DispatcherServlet to map the requests to the following….

here is the spring-servlet.xml

http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd“>

/WEB-INF/jsp/

.jsp

web.xml:

Can anybody tell me the problem please?

It probably has to do with your submit function. You didn’t show that. I ran your function on my page. checkUser is good to go.
