install java on ubuntu

Hi all,
Let us install sun-java6-jdk on ubuntu.

On Ubuntu 10.04:
Now This are the standard method to install it.
Open your terminal by Ctrl+Alt+T

$sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
$sudo apt-get update
$sudo apt-get install sun-java6-jdk

Now I guess You will encounter with this problem in last step.

Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jdk has no installation candidate

Now the solution to this is:

$sudo add-apt-repository ppa:ferramroberto/java
$sudo apt-get update
$sudo apt-get install sun-java6-jdk

And finally you have installed sun java6 on your ubuntu 10.04

Open your terminal by Ctrl+Alt+T
Enter following commands and you will get sun java6 installed on your system.

$wget https://github.com/flexiondotorg/oab-java6/raw/0.2.6/oab-java.sh -O oab-java.sh

This will download the script to install sun java.
After that provide executable permission to that script.

$chmod +x oab-java.sh

And after that execute the script

$sudo ./oab-java.sh

I don’t know who is the author of this script, but hats off to that guy, that made our work so easy to install java.
