java.sql.SQLException

[rubbaninja]

Having problems access a Java applet through our Proxy or ISA server.

Here is the error:
Opening

http://xxx/xxx/servlet/ThinAccessServlet

Connecting

http://xxxxx/xxx/servlet/ThinAccessServlet

with proxy=172.24.254.80:80
java.sql.SQLException: java.io.FileNotFoundException

http://xxx/xxxx/servlet/ThinAccessServlet

at EqeMain.init(EqeMain.java:520)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
Modality pushed
Modality popped

Logs anywhere and everywhere show nothing wrong... If I go straight through the firewall and avoid the proxy or ISA server it will work just fine. Could it be a cache issue on the proxies? Is it attempting to connect back on 443?
The techs at the site we are trying to get to have NO clue.

Additional info:
