Sun JDK on Ubuntu (10.04 and later)

There is just something about using the Sun (Oracle) JDK that makes me all warm inside. So when it was pulled from standard apt repos, and being a lunix novice I was a bit irked. For some time I had stooped to simply installing it from provided binaries, which works, but is a pain in the arse. I recently discovered an article which almost gets me back to where I want to be, installing the JDK from apt. A few tweaks and here is what will get you there:
sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
sudo apt-get update
sudo apt-get install sun-java6-jdk
sudo update-alternatives --config java
Simple enough.
