How to Install Java JDK 7 X64 on Linux Fedora 17 Gnome3 64-bit Easy Visual-Guide

Hi! The Tutorial shows you Step-by-Step How to Install and Getting-Started with the Oracle-Sun Java JDK 7 x8664 Release for Fedora 17 GNOME3 x8664 Desktop.

Especially relevant: at the Same Time I’m also illustrating here How to Install the New Downloaded .rpm Packages with Dependencies on Fedora 17 GNOME3 Desktop :)

The Screenshots of Installation Correspond to the Install on a Fedora 17 GNOME Desktop but the Procedure on KDE, XFCE… Should be Near Identical.

Finally, to the article Bottom Link to the Installation Guide for Apache Tomcat7 Server Java JEE on Fedora Linux.

1. Download Oracle Java SE JDK 7:

   JDK 7 x64 tar.gz
   On the JDK Section Select the x64.tar.gz Release

2. Open Terminal Window
   (Press “Enter” to Execute Commands)

   

   In case first see: Terminal QuickStart Guide.

3. Installing Oracle-Sun Java JDK

   If Got “User is Not in Sudoers file” then see: How to Enable sudo

   cd /[path2]/jdk*.rpm

   YUM will Automatically Manage and Download the Eventual Dependencies Also for Local Packages :)

   You Can Safely Ignore Eventual Installation Errors: “Could not open input file…”.
