Hello,
i followed the steps to upload an applet to my server.
When i start it, it shows a loading screen and popups.
After accepting the security hints, the dimensions i set for my applet are completely white.
So practically, i have a whitescreen after loading the project.
Check it yourself: http://baalbaki.de/bpa/run-applet.html
Same for the jMonkey demo applet: http://jmonkeyengine.org/demo/applet/
Does one of those applets run for you?
Sincerly yours,
Marcel Baalbaki
