To enable the Java plugin in Firefox under our Fedora 64 or 32 bits, this is what we need to do, a simple symbolic link:
64 bits: ln -s /usr/java/latest/jre/lib/amd64/libnpjp2.so /usr/lib64/mozilla/plugins
32 bits: ln -s /usr/java/latest/jre/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins/
This is assuming that we have properly installed JDK first. If you see, we are pointing to the latest java instalation, this will be usefull when we update our java version.
We can check if everything worked out fine over here:
If everything is working correctly, we should see an output like this:
Hope this works for you.
