I don't have problem to set system properties from my applet since I have
grant the applet all permission.
The Applet need to access some ADDE files on another serve other than the
server where the applet is loaded.
The applet is on
http://virga.larc.nasa.gov/applet.html
The adde is on
adde://omega.larc.nasa.gov/text?file=RESOLV.SRV
