Here is a class I have been using to manage the mappings in my applications.
It has some convenience methods so you don't have to repeat your self all
the time when you need to get an InputSource. Thought I would share it with
you in light of the current thread. All the methods are static and if you
addMapping(String s) it will clear out your mappingPath so you should all go
and put in one for a default or set it each time.
