While the above steps result in a working Java install it can cause
problems if you want to switch back to the Fedora supplied GCJ etc.

The recommended approach is to download the nosrc.rpm file from
jpackage.org and then use these to convert the Sun package 
into an installable RPM by following http://www.jpackage.org/nosrc.php

The file you want is probably:
http://www.jpackage.org/browser/rpm.php?jppversion=1.7&id=7539
