我在jsp上想调用一个存储过程，但需要时间太长，想用个进度条提示用户，那位高手有jsp进度条的源代码啊，小弟先谢过啦
------解决方案--------------------
楼主大致 计算 一下时间用 技术显示啊
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>counter</title>
<script language="javascript" type="text/JavaScript">
function Counter(nMax,nInterval)
{
this.maxTime=nMax;
this.interval=nInterval;
this.objId="timer";
this.obj=null;

this.start=function()
{
this.obj=document.getElementById(this.objId);
if(this.num>0) setTimeout(this.run,this.interval*1000);
