compatibility with netscape? unfortunately, that's the problem right now.
netscape has its own security architecture. to get signed applets
to work with netscape you'll have to refer to:

http://developer.netscape.com/software/signedobj/index.html

also, you can try SUN's new activator, which allows you to replace
netscape's build-in JVM with SUN's JRE, which would allow the signExample
to work. however, the activator product is currently available for
IE. a version for netscape should be out soon. for more information:

thanks,
charlie
