I got a applet which access the java.vendor variable in two method,
these two method is called by javascript.
when I try to run it at netscape6, the following error appear. As
java.vendor should not be a protected property, so I don't know why I
will have such security error, please help.

java.security.AccessControlException: access denied
(java.util.PropertyPermission java.vendor read)

I think there is a bug in LiveConnect: javascript doesn't have any
applet security so that all security checks fail. Wayde Wyatt noticed
that LiveConnect can't load images in applets either.
