February 1st, 2013 by Regaz



The Guide Shows You Step-by-Step How-to Install and Getting-Started with the Latest Oracle-Sun Official Java JDK 7 32bit Release for Fedora Linux 18 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 the Easiest Way of Installing the New Downloaded .rpm Packages with Dependencies on Fedora 18 KDE4 Desktop :)

The Screenshots of Installation Correspond to the Install on a Fedora 18 KDE4 Desktop but the Procedure on Gnome, Xfce, Lxde… Should be Just the Same.

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

Java Baloon
  1. Download Oracle-Sun Java SE JDK 7:

    Oracle JDK x86.tar.gz
  2. Double-Click on Archive and Extract into /tmp Linux KDE4 JDK Extraction
  3. Open Terminal Window
    (Press “Enter” to Execute Commands)
    Fedora Linux16-17-18 Kde4 Open Terminal
  4. Relocate Oracle Java JDK
    su 

    If Got “User is Not in Sudoers file” then Look: Solution

    if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi

    The above command is used to create a jvm directory if not already there.

    chown -R root:root /tmp/jdk1.7*

    Reiterate the Execution Permission over the Java binaries

    chmod -R +x /tmp/jdk1.7*/bin

    Finally Shift the Java content with

    mv /tmp/jdk1.7* /usr/lib/jvm/
  5. Updating System Java to Oracle JDK
    update-alternatives --install \
    /usr/bin/java java /usr/lib/jvm/jdk1.7*/bin/java 1065
    update-alternatives --install \
    /usr/bin/javac javac /usr/lib/jvm/jdk1.7*/bin/javac 1065
    update-alternatives --install \
    /usr/bin/jar jar /usr/lib/jvm/jdk1.7*/bin/jar 1065
    update-alternatives --install \
    /usr/bin/javaws javaws /usr/lib/jvm/jdk1.7*/bin/javaws 1065

    Checking or Setting the System Java Version in Use with

    update-alternatives --config java

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

  6. Optionally Set Java Environment Variable

    su <myUser>
    nano $HOME/.bashrc

    Append:

    export JAVA_HOME=/usr/lib/jvm/jdk1.<X.Y_uZ>

    Ctrl+x to Save & Exit from nano :)

    source $HOME/.bashrc
