Installing Java on your Ubuntu system is quite easy. Just follow the instruction below.

First download the latest JDK (SE or EE) from Sun Microsystem, In this tutorial we are use the JDK SE 6u21. Your downloaded file will look something like this jdk-6u21-linux-i586.bin

After you finish the downloading, unpack the .bin file using the Broune Shell (sh) command. Assuming that you download the .bin file on your Desktop.

cd ~/Desktop
sudo chmod a+x *.bin
sudo sh ./jdk-6u21-linux-i586.bin

Rename the unpacked folder to something like JDK6u21 and move the directory to your desire place of your JDK.

sudo mv jdk-6u21-linux-i586 /home/greatxam/JDK6u21

Now, update your system so it will recognize your new Java installation.

sudo update-alternatives --install /usr/bin/java java /home/greatxam/JDK6u21/bin/java 300
sudo update-alternatives --config java

And add Java Run-Time Environment (JRE) plugin to your browser.

sudo ln -s /home/greatxam/JDK6u21/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/firefox/plugins
