<%@ page language="java" contentType="text/html; charset=GB18030"
pageEncoding="GB18030"%>

</body>
</html>

TextServle的代码
package com.lizhe;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.li.UserManager;

public class TextServle {
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String username = request.getParameter("username");
UserManager lo = new UserManager();
lo.add(username);
request.getRequestDispatcher("/add_success.jsp").forward(request, response);;
}

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request,response);
}
}

web.xml
的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
