服务端flash不能显示

Question

用swfobject.js嵌入flash，在本地的html里可以正常显示，但是放到服务端就不能显示？
如果不使用swfobject.js,直接使用object标签是可以正常显示的。`

var swfVersionStr = "10.0";
var xiSwfUrlStr = "playerProductInstall.swf";
var flashvars = {};
var params = {};
params.quality = "high";
params.bgcolor = "#ffffff";
params.play = "true";
params.loop = "true";
params.wmode = "transparent";
var ctlAttrs = {};
ctlAttrs.id = "controlBar";
ctlAttrs.name = "controlBar";
swfobject.embedSWF(
    "controlBar.swf", "flashContent",
    "75", "160",
    swfVersionStr, '',
    flashvars, params, ctlAttrs);  
var turnAttrs = {};
turnAttrs.id = "mapTurn";
turnAttrs.name = "mapTurn";
swfobject.embedSWF(
    "mapTurn.swf", "Div2",
    "120", "55",
    swfVersionStr, '',
    flashvars, params, turnAttrs);`
