下面是JSP页面



<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>



<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>

    <base href="<%=basePath%>">

    

    <title>edit pet page</title>

    

	<meta http-equiv="pragma" content="no-cache">

	<meta http-equiv="cache-control" content="no-cache">

	<meta http-equiv="expires" content="0">    

	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

	<meta http-equiv="description" content="This is my page">

	<!--

	<link rel="stylesheet" type="text/css" href="styles.css">

	-->



  </head>

  

  <body>

  <form name="pet" action="DoEditPet"  >

  	

  	 pet_name:<input name="name"type="text" value="${sessionScope.petinfo.pet_name}"/><br/>

  	 pet_owner_email:<input name="email" type="text" value="${sessionScope.petinfo.pet_owner_email}"/><br/>

  	 <input type="reset" value="重置"/> <input type="submit" value="提交"/>

  	 

  </form> 

  </body>

</html>

以下是 servlet java 代码



package Contrallor;



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 javax.servlet.http.HttpSession;



import dao.impl.PetinfoEditBizJdbcImpl;



import entity.Petinfo;



public class DoEditPet extends HttpServlet {



	/**

	 * The doGet method of the servlet. <br>

	 *

	 * This method is called when a form has its tag value method equals to get.

	 * 

	 * @param request the request send by the client to the server

	 * @param response the response send by the server to the client

	 * @throws ServletException if an error occurred

	 * @throws IOException if an error occurred

	 */

	public void doGet(HttpServletRequest request, HttpServletResponse response)

			throws ServletException, IOException {



		HttpSession session = request.getSession();

		Petinfo petinfo = (Petinfo)session.getAttribute("petinfo");



		petinfo.setPet_name(request.getParameter("name"));

		petinfo.setPet_owner_email(request.getParameter("email"));

		System.out.println(petinfo.getPet_name());

		String result =  new PetinfoEditBizJdbcImpl().edit(petinfo);



		if(result.equals("success"))

			response.sendRedirect("/pet/showpet.jsp?id="+petinfo.getPet_id());

		else

		{

			request.setAttribute("errormessage", "编辑错误");

			request.getRequestDispatcher("/error.jsp").forward(request, response);

		}

	}



	/**

	 * The doPost method of the servlet. <br>

	 *

	 * This method is called when a form has its tag value method equals to post.

	 * 

	 * @param request the request send by the client to the server

	 * @param response the response send by the server to the client

	 * @throws ServletException if an error occurred

	 * @throws IOException if an error occurred

	 */

	public void doPost(HttpServletRequest request, HttpServletResponse response)

			throws ServletException, IOException {



		doGet(request,response);

	}



}

在更新成功后跳转到另外一个显示页面
