Invoking flash(swf) file in jsp, Not working when accessed from external network

hi guys,

i got a flash swf file embeded in my jsp. The flash files reads a xml file and displays a chart based on values retrieved from xml file.

This procedure works fine when accessed from any machine on my local network.

BUT, the flash file doesnt load the xml file to display chart when accessed from a machine in the external network.

Please suggest.

This is how i embed the flash file in my jsp :
 
  <object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" name="gm" width="100%" height="100%" id="gm">
    <param name="movie" value="chart.swf">
    <param name="quality" value="high">
    <param name="menu" value="false">
    <embed src="chart.swf" width="100%" height="100%" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" menu="false" name="gm"></embed>
