audio and firewalls

[owls]

I am trying to play a simple wave file in an applet on my system that contains a firewall. I read that is a firewall is in place that the sound may not play. I am assuming this is my problem since the same code at home plays the sound. What do I have to do with my code to get around the firewall?

My code is as simple as it gets

jButton1_actionPerformed(ActionEvent e){
play(getDocumentBase(),"songname.wav&quot
}
