jsp用swfobject播放器播放flv文件的路径问题

<div id="container"> <a href=" http://www.macromedia.com/go/getflashplayer">Get the Flash Player </a> to see this player. </div>
<script type="text/javascript" src="../../js/swfobject.js"> </script>
<script type="text/javascript">
var s1 = new SWFObject("../../flash/player-viral.swf","ply","500","400","9","#FFFFFF");
s1.addParam("allowfullscreen","true");
s1.addParam("allownetworking","all");
s1.addParam("allowscriptaccess","always");
s1.addParam("flashvars","file=D://12343.flv");//播放的文件路径
s1.write("container");
//alert("file=${requestScope['videourl'] }");
</script>

为什么只能播放项目里的文件，怎么做才能播放项目外的其它磁盘的文件
