servlet的有关问题,,会的请答,,
Java code
package Conn;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;public class Test extends HttpServlet {/*** The doPost method of the servlet. <br>16:14 2012/7/31* 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 service(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {     //处理中文问题   request.setCharacterEncoding("utf-8");   response.setContentType("text/html;charset=utf-8");   System.out.println("start............");   String username=request.getParameter("username");   String content=request.getParameter("content");   //username=new String(username.getBytes("gb2312"),"utf-8");   PrintWriter out = response.getWriter();   out.write(username);   System.out.println("username>>=="+username);   out.write(content);   out.flush();   out.close();   System.out.println("end");}}

以上是我的一个servlet,在dos窗口中编译的时候,总是报错,说找不到包,,,,,为什么呢,,,真是不明白啊。。。。急死了快,,求解答,,谢谢,,帮帮忙。。

建议把详细的报错信息贴出来

你好,这是因为找不到servlet包的原因,请在dos下键入命令
set classpath=c:\tomcat\common\lib\servlet.jar;%classpath%
记住c:\tomcat\common\lib\servlet.jar是你的jar包的地址,当然有可能你的不是servlet.jar,可能你的脚servlet-api.jar 之类的,这个你要看你的tomact的lib下的servlet包的名字,这个命令之后,再编译就可以通过了,我试过了,可以的,祝你好运,呵呵

首先你的明白:Servlet 是用来干嘛的!

推荐你先首先一下概念,这样你也慢慢首先servlet了,出现问题!就知道从那里下手找问题了!
