Warning: Can't read AppletViewer properties file: /root/.hotjava/properties Using defaults.
Exception in thread "main" java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
Why are you running this as root? Simply run it from a konsole, as user "knoppix".
If you need root privilege, issue "xhost +" from a knoppix session, to allow other accounts to use the X display.
You also need to have the variable DISPLAY defined, "export DISPLAY=:0" shoudl do (but is unnecessary for user "knoppix").
