Hi,

Regarding the "We are working on solving these interoperability issues with Netscape"
comment below, do you know in which version of Netscape and/or JDK that the
"Signed Applet Example" will work when invoked from Netscape (as it already does
from AppletViewer)? I'm using Netscape 4.04 and JDK 1.1.5.

Thanks,

Hi,

It looks like your applet when loaded into Netscape browser was not trusted
to write /tmp/foo. The reason is that the jar file is not correctly
verified by netscape jar verification mechanism. Netscape does not follow
Javasoft's jar file format completely and it only honors RSA signatures
not DSA signatures that is in the SignedAppletExample, which was generated
by Javakey.

We are working on solving these interoperability issues with Netscape.

Thanks!
