Dude,
I attached the java files for a struts prototype. Not to confuse you but to
give you a fresh idea of the composition of the interfaces.
I am extremely picky about clean understandable functional concise
interfaces that model the natural world.
But this is a fun task. And if you nail it (which should take no more than 3
days) you will feel proud.
Anybody that delivers incomplete code should rightfully receive a hard pie
to the face. I have your source code on my build tree but have not been
inspired enough to begin exercising those. This one may cause me to consider
your library. So you have my confidence.
Holler if you need any assistance.
Hoping for the best.
Best regards
Ken in nashua
