Question

帮我看看代码哪里有错没，Servlet ApI

FirstServlet.java
package com.demo;
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import com.demo.Student;
public class FirstServlet extends Student{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
String name;String sno;String location="";
response.setCharacterEncoding("gb2312");
response.setContentType("text/html;charset=gb2312");
name = request.getParameter("name");
name = new String(name.getBytes("iso8859-1"),"gb2312");
sno = request.getParameter("sno");
sno = new String(name.getBytes("iso8859-1"),"gb2312");
w_name(name);
w_sno(sno);
location="/SecondServlet";
RequestDispatcher dispatcher=request.getRequestDispatcher(location);
dispatcher.forward(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
doGet(request, response);
}
}
还有些代码超过字数了，到这里来看一下吧~~~tieba.baidu.com/p/2941748620

FirstServlet类要继承HttpServlet，要不然哪里来的doPost方法

你的代码编译没有出错吗？
