U don't need any signing unless u r going to install vrml97.jar as
installed extension via extension mechanism of JRE1.3. VrmlLoader
throws an exception connected with creating a new ClassLoader or smth
like that, which is not allowed 4 applet. But this happens only when
it IS loaded via Inet. But if it is in your ext dir (if u r running
JRE1.2.1 or lower, u'd copy all extensions to the lib dir as well,
since JPlugin doesn't look them up at lib/ext dir) everything should
run smoothly. So, check up whether it IS in ext dir of your JRE
_plug-in_ (not of SDK). Also check up your html code and throw out
the reference, if any, to this jar from archive property. This way u'd
be sure that vrml97.jar is not loaded via network.
