Java Installation Guide on OpenSUSE Linux

Just wanna share my experience when I installed Java on OpenSUSE linux. Before I got it, I was very confused. Because when I checked my java -version is like the old version still from OpenSUSE bringing. Follow this instructions.

1. Download java the last version, as example I use jdk-6u5-linux-i586.bin.

2. Open konsole/terminal (Alt+F2+konsole), and login to root.

3. Copy jdk-6u5-linux-i586.bin to /opt folder.

4. Change mode: linux:/home/kirman # chmod +x /opt/jdk-6u5-linux-i586.bin

5. Execute the installer linux:/opt # ./jdk-6u5-linux-i586.bin
When appear the license agreement, press Ctrl+C to finish read, press y and enter. After that you will see new folder as /jdk1.6.0_05 on /opt folder.

6. Check installation java -version. If you see like this
java version “1.5.0_12
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_12-b04)
Java HotSpot(TM) Client VM (build 1.5.0_12-b04, mixed mode)

You need to change the path installation. Before it, you need to remove /usr/bin/java by linux:/opt # rm /usr/bin/java. Because the first version java from OpenSUSE linux intallation is saved here.

7. Now we need to make link from your new installation by linux:/opt # ln -s /opt/jdk1.6.0_05/bin/java /usr/bin/java.

8. Check java -version again, if you find like this the installation is right.
linux:/opt # java -version
java version “1.6.0_05″
Java(TM) SE Runtime Environment (build 1.6.0_05-b13)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode, sharing)
linux:/opt #

9. Now we need to set classpath in order compile from any where. Make a file .bash_profile, as sample java.bash_profile. Write this one to it and safe on home folder, for example /home/kirman folder.
JAVA_HOME=/opt/jdk1.6.0_05
export JAVA_HOME
export PATH=$PATH:$JAVA_HOME/bin

10. Reboot computer and check environtment by
linux:/home/kirman # echo $JAVA_HOME
/opt/jdk-6u5-linux-i586

If the result is like that, so your installation is right.
