*/ 
public HelloWorldServlet() { 
    super(); 
    // TODO Auto-generated constructor stub 
} 

/**

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
    PrintWriter out = response.getWriter(); 
    out.println("Hello World"); 
}

你可以发布你的代码和mot图片吗？这会让阅读更容易。代码粘贴 – 2013-02-10 04:51:52

@junaidp您使用JDK 7还是JDK 6？你用tomcat6吧？ – erhun 2013-02-10 13:15:23

删除您的bin目录，并重新编译您的项目。同时检查新生成的班级是否放在垃圾桶中
