flash在jsp中不能显示?

flash在jsp中不能显示?代码如下:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>小海个网站</title>
</head>


<body>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cabversion=7,0,19,0" width="100%" height="100%">
<param name="movie" value="./img/123.swf"></param>
<param name="quality" value="high"></param>
<embed src="./img/123.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="100%" height="100%">
