Java Code to Work With MillennialMedia, SMAATO and NexAge Web Advertising APIs

I wrote yesterday about [link id='434' text="my (mostly) negative experience working with these companies"], but some of you might give it a try and maybe your results will be much better or maybe things have actually improved lately. In any case, the code here should get you up to speed covering most of the dirty work of working with these companies' APIs.

I will post 4 classes here:
