servlet问题

hunterqu

为何servlet的java程序编译编译通过了，却在浏览器的地址栏输入地址后提示404错误
环境：jdk6.0+tomcat6.0
1.helloworld.java

package test;
import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class helloworld extends GenericServlet{
   public void init(ServletConfig config)throws ServletException
   {
     super.init(config);
     log("servlet has been inited now");
    }
    public void service(ServletRequest request,ServletResponse response)throws IOException,ServletException
    {
        PrintWriter out=response.getWriter();
        response.setContentType("text/html,charset=gbk");
        out.print("");
        out.print("");
        out.print("the first servlet");
        out.print("");
        out.print("");
        out.print("第一个servlet运行成功！
");
        out.print("info:"+this.getServletInfo());
        out.print("");
        out.print("");
    }
    public String getServletInfo()
    {
      return "the first servlet,by caxton!";
    }
    public void destroy()
    {
     System.out.print("the first servlet,destroyed!");
    }
}

2.编译



3. 修改web.xml
  Welcome to Tomcat
  
     Welcome to Tomcat
  
  
  helloworld
  test.helloworld


   helloworld
   >/helloworld
   

4.输入地址
http://localhost:8080/10/helloworld
显示为：
HTTP Status 404 - /10/helloworld
type Status report
message /10/helloworld
description The requested resource (/10/helloworld) is not available.
Apache Tomcat/6.0.16
