Simple invoice generator in Java. Made using Swing and iText.
Hey, it works ;). Even on multiple platforms (Windows and Linux) Attached is the .jar, but you can check out the code yourself and make artifacts.
Note to self:
Should probably make tests or something, wouldn't be the first ones I make. Could also be more ObjectOriented, since it is Java at the end of the day. The UI sucks, but then again, it works :).
