progressbarjsp.jsp

这个是用jsp做的一个系统。不过我没调出来

<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%!
int counter = 1;//注意：多用户将共享此变量，此进度条只适合单用户
%>
<%
 String task = request.getParameter("task");
        String res = "";
        
        if (task.equals("create")) {
            res = "1";
            counter = 1;
        }
        else {
            String percent = "";
            switch (counter) {
                case 1: percent = "10"; break;
                case 2: percent = "23"; break;
                case 3: percent = "35"; break;
                case 4: percent = "51"; break;

                case 7: percent = "89"; break;
                case 8: percent = "100"; break;
            }
            counter++;
                
            res = "<percent>" + percent + "</percent>";
        }
        
       // PrintWriter out = response.getWriter();
        response.setContentType("text/xml");
        response.setHeader("Cache-Control", "no-cache");
        out.println("<response>");
        out.println(res);
        out.println("</response>");
        out.close();
