VELOCITY (XML) - COCOON (PDF)

[Terry Anderson <ta...@highergear.com>]

Looking for help posting xml (created with velocity) to cocoon to create
a pdf. I successfully create the pdf with the file-generator (xml file
saved to disk), but having difficulty with the stream-generator. I've
attached my code for review (sorry for length).

Thanks for any assistance!   TA
