Install Java Browser plugin for Firefox 64-Bit in CentOS/Redhat

Download the latest 64-bit RPM package from main Java homepage. Install it as:

rpm -ivh <package-name>.rpm

And, add the plugin to Firefox with:

# cd /usr/lib64/mozilla/plugins
# ln -s $(find / -mount -name libnpjp2.so)

If 'ln -s $(find / -mount -name libnpjp2.so)' fails, then, first find the file 'libnpjp2.so' and supply the path as:

# ln -s <path-to-libnpjp2.so>

Restart your browser and you will have the working Java plugin for Firefox.
