Same way as you would on a Windows machine. Remember, Java is platform independent.

The java compiler can be used like
javac /pathToJavaFile

You'll most likely have to download the Sun JDK as it's not packaged with Ubuntu by default due to licensing issues. You can get the JDK from java.sun.com

Once you've installed the JDK you will probably need to use update-alternatives from the terminal to set your shiny new JDK as the default target for all calls to java and javac otherwise it will still be pointing to the old non-Sun JRE.

After that all should be well and you should be away!

you can also install sun java 6 from the repos, provided you enable the universe and multiverse repos.

sudo aptitude install sun-java6-jdk sun-java6-jre sun-java6-bin sun-java6-plugin
