Fedora 17 - Install Java

There are two ways to install Java. The simplest is to install the open source variant from the Fedora repository.  It's easy to install, and most importantly it keeps itself up to date.

The second way is to install the official Sun Java binaries manually. The benefit is you'll be working with the official libraries.  The downside is updates are done manually, instead of automatically through the Fedora repos.

I would highly recommend using the open source Java.  Simply install it, and forget it!  I've yet to have an issue with it.
