404에러

안녕하세요.

아래처럼 작성했는데 login.jsp에서 아이디/비번 입력 후 서밋 시 에러가 발생합니다.

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html>

<html>

<head>

<meta charset="UTF-8">

<title>Insert title here</title>

</head>

<body>

<form action="loginCon" method="post">

ID : <input type="text" name="mID"><br>

PW : <input type="password" name="mPW"><br>

<input type="submit" value="login">

</form>

</body>

</html>
