I'm running Fedora, and, despite the fact that I have java installed, java appletts are not coming up correctly. A box comes up that says "[t]his page contains information of a type (application/x-java-vm) that can only be viewed with the appropriate Plug-in. " Would anyone have any advice as to how to get this problem fixed?

what browser ??
i can only give my example and my systems a little strange
basically you have to make a symbolic link in the mozilla and/or firefox plugin drectory
that points to the java plugin
mine is
/opt/firefox-0.8/lib/mozilla-1.6/plugins/libjavaplugin_oji.so -> /opt/j2sdk/j2sdk-precompiled/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

i have another link in /usr/lib/mozilla-1.6/plugins
put one for each browser

do
ln --help
for the syntax for making links
generally do
ln -s TARGET [LINK_NAME]
make sure you don't get target and linkname reversed or you errase something important

opera is a little different for old 6 or pre 6 versions you put the path to jre/plugin/i386/ns4
in the plugins config thing

Ah, sorry, I'm using Mozzilla 1.4.1.

Thansk for the advice...I'm assuming that it all still applies? I'm sorry, I'm still a bit new to this.
