Java Support in Firefox

[Nathan W]

has anyone been able to get .jsp files/java applets to work in Fedora?

i'm currently using openjdk and the openjdk browser plugin, and visiting 
http://www.java.com/en/download/help/testvm.xml says that java is 
working fine, and indeed it seems to be, but the applet at 
http://www.gokgs.com/applet.jsp seems to be just a grey box :(

google's not helping, any suggestions?

thanks in advance,

nathan
