Chapter 02: Install Java

Well, this is the shortest chapter of them all, as I decided to give the standard OpenJDK a shot. Install it the simple way (through the command line) with:

$ sudo apt-get install icedtea6-plugin openjdk-6-jre openjdk-6-jdk ant

If you are using another operating system than Ubuntu, please visit http://www.oracle.com/technetwork/java/javase/downloads/index.html and download the appropriate installation package from there.

Observe that you need the "JDK" package. Only the "JRE" is not sufficient.
