What is the cause for an HTTP 405 Error in GAE application?

I'm using eclipse to develop a Google App Engine application. I am on a login page, but I click login, then it shows "Error 405 HTTP method POST is not supported by this URL"?

Here is my servlet code:

my LgServlet.java:

package com.lan;

import java.io.IOException;
import javax.servlet.http.*;

public class LgServlet extends HttpServlet {
    /**
     * 
     */
    private static final long serialVersionUID = 1L;

    @Override
    public void doPost(HttpServletRequest req,HttpServletResponse resp)
            throws IOException {
                check(req,resp);
            }
    @Override
    public void doGet(HttpServletRequest req,HttpServletResponse resp)
            throws IOException {
                check(req,resp);
                }

    public void check(HttpServletRequest req,HttpServletResponse resp)
            throws IOException {
        if(req.getAttribute("userID").equals("admin")&&req.getAttribute("userPassword").equals("123456")){
            resp.setContentType("text/plain");
            resp.getWriter().println("Hello Admin");
        }
}

}

my web.xml:

<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5">
    <servlet>
        <servlet-name>lg</servlet-name>
        <servlet-class>com.lan.LgServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>lg</servlet-name>
        <url-pattern>/lg</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

part of index.jsp:

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

I hope someone can help explain to me why I'm getting this error?

Thanks!

Try changing 

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

to 

<form action="/lg" method="post">

Nothing else looks out of place. I got this error recently, but it was because i was calling super.doPost() in my doPost call.
