Deployment failure

[Jodokus]

I have made an applet running locally without problems under windows.
After FTP-ing it to my site the applet-window stays empty.
Running locally under Ubuntu doesn't work either.
I think I checked the capitalisations of my paths.

Any suggestions how to show my applet to the world?
