How to Install Oracle Java JDK 7 on Fedora 17 KDE4 32bit Linux Easy Visual-Guide

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.

1. Download Java JDK 7:

   Java JDK 7 Linux .rpm
   On the Oracle-Sun Java SE JDK Section Select the i586.rpm Release

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.

   

   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

   

   Follow to Confirm and Authorize Also if you Are Warned About Installation of Unsigned Content…

   
   

5. Updating System Java to Oracle JDK

   Checking or Setting the System Java Version in Use with.

   update-alternatives --config java

   And for the Java Compiler instead:

   sudo update-alternatives --config javac

   To Switch of Java Version Just Enter the Reference Number on First, Column. :)

6. Optionally Set Java Environment Variable.

   nano $HOME/.bashrc

   Append:
