import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ShowTimesServlet extends HttpServlet {
           private static final long serialVersionUID =1L;
           protected void doGet(HttpServletRequest request,
         HttpServletResponse response ) throws ServletException, IOException{
              ServletContext context = getServletContext();
              integer times =(integer) context.getAttribute("times");
              if(times==null ){
              times=new = Integer(1);}
              else{times=new Integer(times.intValue()+1);}
              response.setContenType("text/html;charset=utf-8");
   PrintWriter out=response.getWriter();
   out.println("<html><head><title>");
   out.println("网页访问统计");
   out.println("</title></head><body>");
   out.println("当前网页被访问了");
   out.println("<font color=red size=20>"+times+"</font>次")
}
 protected void doPost(HttpServletRequest request,
 HttpServletResponse response) throws ServletException , IOException{
 this.doGet(request,response);}
