jPlayer does not play MP3 files

I tried to set up a playlist with jPlayer, like this demo shows.

You can find my code here.

I've checked the playList var, everything is okay (it contains all mp3 URLs for each <article> element which represents a track).

The swfPath to jPlayer.swf is correct too.

So I really don't understand where is the problem ? 开发者_开发问答Any idea ?

Thank you. :-)

The Jplayer.swf is not on the same domain as the rest of the code.
