I am using FBML to embed a swf file into my facebook application, but it shows the message that movie is not loaded. The piece of code that I am using for this is:
echo ”
< fb:swf
imgstyle=\”border-width:3px; border-color:white;\”
swfsrc=’apsolute url of the .swf in the server where I am hosting’
width=’340′
height=’270′
flashvars=”
swfbgcolor=’333333′
wmode=’opaque’
/>”;
If you don’t need your flash application to interact with Facebook, there’s an easy workaround to your problem: http://anandnalya.com/2009/01/15/embedding-flash-object-in-facebook-apps-fbml/
