Install Oracle JDK 7 on Oracle Linux 6.X GNOME 64-bit
The Guide shows you Step-by-Step How to Install Oracle-Sun Java JDK 7 x64 Release on a Oracle-Linux 6.x GNOME 64-bit desktop.
After Installing you will need to Use the update-alternatives Tool to Update your System Java to Sun SE JDK 7.
To the Post Bottom you Find Link to Guide on Installing Tomcat7 Java Web-Server for Oracle-Linux Distro.
The Screenshots of Installation Correspond to the Install on a Oracle Linux 6 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 :)
