I am getting this error on using post method in my form-- HTTP Status 405 - HTTP method POST is not supported by this URL.

我register.html文件如下：

Register form

Name:

Email ID:

Password:

我Register.java servlet代碼是如下

package Glassfish;

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.*;

import javax.servlet.*;

import javax.servlet.http.*;

import java.sql.*;

/**

* @author Intel I 5

*/

public class Register extends HttpServlet {

@Override

protected void service(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

doPost(request, response);

response.setContentType("text/html;charset=UTF-8");

PrintWriter out = response.getWriter();

String name = request.getParameter("name");

String email = request.getParameter("email");

String pass = request.getParameter("pass");

try{

//loading drivers for mysql

Class.forName("com.mysql.jdbc.Driver");

//creating connection with the database

Connection con=DriverManager.getConnection

("jdbc:mysql://localhost:3306/test","user","pass");

PreparedStatement ps=con.prepareStatement

("insert into register values(?,?,?)");

ps.setString(1, name);

ps.setString(2, email);

ps.setString(3, pass);

int i=ps.executeUpdate();

if(i>0)

{

out.println("You are sucessfully registered");

}

}

catch(Exception se)

{

se.printStackTrace();

}

}

我的web.xml文件如下

Register

Glassfish.Register

Register

/Register

我已經嘗試了HTTP錯誤405中提供的所有實例，用于堆棧溢出中的post方法但沒有用。
