It gives you the current directory of the user.

You should not depend on external variables, as it is not used if you 
use executable jars etc.

Try looking at 
MyClass.class.getProtectionDomain().getCodeSource().getLocation() (not 
compiled, just derived from javadoc) to get an URL you can work with.
