1. Download the JDK 6 Update 3 from Sun Microsystems. Click on this link JDK 6 Update 3.(Although the link says JDK java update 3, the link will actually give you the current update.)
   
   
2. Now click on the Download button over to the right for the JDK 6 Update 3.
   
   
   
   
   
   
3. On the next screen, click on the radio button to accept license agreement.
   
   
   
   

4. Now click on the 'Linux RPM in self-extracting file (jdk-6u3-linux-i586-rpm.bin)'. The file you download will differ in name for you depending on the java version.
   
   
   
   
5. Save the file to disk in a directory of your choice(e.g. /tmp or your Desktop, I will use the /tmp directory.
   
   
   
   
   

6. Click on Applications-System Tools-Terminal to open a terminal and then switch to root user. Make the directory /opt/java and move the java JDK file to it. Pay close attention when you run the command mv /tmp/jdk* /opt/java because it might not work if you saved the java file somewhere else. So, make sure to use the correct path of the location of the java update you downloaded.
   
   

   [jesse@localhost ~]# su - Password: [root@localhost ~]# mkdir /opt/java [root@localhost ~]# mv /tmp/jdk* /opt/java

   
   
   
7. Let's remove the 'icedtea java' because it doesn't load the applets. I could not get it to work with any applets other than with Sun's java test webpage, which displayed a dancing character. Also, JDK java plugin wouldn't work with icedtea installed. Once removed, JDK worked fine.
   
   

   [root@localhost ~]# yum list | grep icedtea | xargs yum -y remove

   
   
   

8. Now lets add all java (GNU libgcj) packages for the open source java. We want to be able to switch back and forth if need be.
   
   

   [root@localhost ~]# yum install '*gcj*'

   
   
9. Install wget just in case it is not installed and switch to repos directory.
   
   

   [root@localhost ~]# yum install wget [root@localhost ~]# cd /etc/yum.repos.d

   
   Add the JPackage key and repository.
   
   

   [root@localhost yum.repos.d]# rpm --import http://jpackage.org/jpackage.asc [root@localhost yum.repos.d]# wget http://www.jpackage.org/jpackage17.repo

   
   
10. Now disable the JPackage17 repository so it won't check it for updates. I had some problems with update dependencies coming from this repository.
    
    
    

    [root@localhost yum.repos.d]# gedit jpackage17.repo

    
    
    
11. Change the highlighted line, enabled=1 to enabled=0 and save the file and exit.
    
    
    

    [jpackage-generic] name=JPackage (free), generic mirrorlist=http://www.jpackage.org/jpackage_generic_1.7.txt failovermethod=priority gpgcheck=1 gpgkey=http://www.jpackage.org/jpackage.asc enabled=1

    
    
    

12. Now install some tools and compatibility utilities.
    
    

    [root@localhost yum.repos.d]# yum -y install rpmdevtools rpm-build compat-libstdc++-33 compat-libstdc++-296

    
    
13. Switch to directory /opt/java and run java JDK installation package. Make sure the highlighted text 6u5 matches your java version, so check your filename and change accordingly. Once you start the installation, press the spacebar until you are prompted to agree to licensing terms. Type 'yes' to answer question and hit enter.
    
    

    [root@localhost yum.repos.d]# cd /opt/java [root@localhost java]# chmod 755 jdk-6u5-linux-i586-rpm.bin [root@localhost java]# ./jdk-6u5-linux-i586-rpm.bin

    
    
14. Install the JPackage Java compatibility package for Sun's JDK
    
    

    [root@localhost java]# yum --enablerepo=jpackage-generic-nonfree install java-1.6.0-sun-compat

    
    
15. Configure JDK to be your default java.
    
    

    [root@localhost java]# alternatives --config java There are 2 programs which provide 'java'. Selection Command ----------------------------------------------- + 1 /usr/lib/jvm/jre-1.5.0-gcj/bin/java * 2 /usr/lib/jvm/jre-1.6.0-sun/bin/java Enter to keep the current selection[+], or type selection number:

    
    Enter 2 to make JDK your default java and press Enter.
    
    
    
16. Now double check to see if JDK is your default java.
    
    

    [root@localhost java]# java -version java version "1.6.0_03" Java(TM) SE Runtime Environment (build 1.6.0_03-b05) Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

    
    If you don't get the output above then something went wrong. Try retracing your steps.
    

17. Open a browser and go to a website that runs java applets. This one will work: Sun java test.
    
    
    
    
    If you see this dancing character and you see 'Java 6 update 3' then your java is configured correctly.

	It was my pleasure. I hope you enjoy Fedora. Remeber, the power is at the command prompt. The more you know, the better you will be able to control how to manage a linux environment. I love it.
