The Guide shows you Step-by-Step How to Install Oracle-Sun Java JDK 7 32-bit Release for Fedora 17 KDE4 i686 Desktop.

After Installing you will need to Use the update-alternatives Tool to Update your System Java to Sun SE JDK 7.

Especially relevant: at the Same Time I’m also illustrating here How to Install the New Downloaded .rpm Packages with Dependencies on Fedora 17 KDE4 Desktop :)

The Screenshots of Installation Correspond to the Install on a Fedora 17 KDE Desktop but the Procedure on GNOME, 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.

Java Baloon
  1. Download Java JDK 7:

    Java JDK 7 Linux .rpm
  2. Select the Open with Package Installer Option or Double-Click After

    We Suppose that you Browser like Firefox will Prompt you About the Downloading Procedure to Follow like Here.

    Install the Latest Java on Fedora 17 KDE 1

    If Not Prompted then Double Click on the Downloaded tar.gz Archive…

  3. When the Download is Achieved you will be Automatically Prompted for Installing

  4. After all the Dependencies are Fulfilled Java is Ready to Be Installed

    Checking or Setting the System Java Version in Use with.
