The Guide shows you in Easy Steps How to Install the Latest Oracle-Sun Official Java JDK 7 Release for openSUSE 11-12 & Milestone GNOME i686 Desktop.
Especially relevant: At the Same Time I’m also illustrating here the Easiest Way of Installing the New Downloaded .rpm Packages with Dependencies on openSUSE GNOME Desktop :)
The Screenshots of Installation Correspond to the Install on a OpenSuse 12 GNOME Desktop but the Procedure on KDE, XFCE… Should be Near Identical.
So Take the Time of Carefully Reading and Executing the Instructions Contained Here and All should Work Like a Breeze :)
