The Guide Shows You Step-by-Step How to Install Oracle-Sun Java JDK 7 x64 Release for Linux CentOS 6 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 Installing the Tomcat7 Java Web-Server for CentOS Linux Distro.

The Screenshots of Installation Correspond to the Install on a CentOS 6 Gnome Desktop but the Procedure on KDE, Xfce… Should be Near Identical.

Following the Easiest and Practicable Way I have Expressly Excluded the Use of Terminal Commands here.

So Take the Time of Carefully Reading and Executing the Instructions Contained Here and All should Work Like a Breeze :)
