My pi runs a raspbian distro (2013-09-25-wheezy-raspbian.zip)

Java

What the raspberry page officially recommends is the jdk. (Source: http://www.raspberrypi.org/archives/4920).

sudo apt-get update && sudo apt-get install oracle-java7-jdk

However, this doesn't include a server on the pi. The jre needs to be installed instead.

Look at LSB init scripts for more information.

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)
