Java on Ubuntu 13.04 (Raring Ringtail)

Installing Oracle Java on Ubuntu can be a pretty daunting task. After reading the Ubuntu documentation here:

Java

I came across this nice github project:

oab-java6

Simply run

git clone https://github.com/flexiondotorg/oab-java6.git

Then cd into oab-java6 and run

sudo ./oab-java.sh

This will set up a local apt repository for Sun Java 6 and Oracle Java 7. Now run

sudo apt-get update

to add the packages from the repository. As the documentation states, you can now run

sudo apt-get install sun-java6-jre

To install Java 6 runtime environment.

One small thing to note:

I had to run

sudo update-alternatives --config java

and select the Sun JRE since the system defaulted to IcedTea.

Now do

java -version

to see what you have!
