Hello,
I am hoping that someone will be able to tell me what I've done wrong. I am
attempting to build a GUI interface for using FOP for a customer to publish
their XML based manuals to PDF. I am pretty green in Java, but following a few
tutorials, I have managed to create an app that 90% works. FOP is processing
the XML, but it is not rendering any of the graphics into the PDF. When I run
the same XML/XSL-FO from the CMD prompt, everything runs fine. I am using FOP
1.0.
I have attached a .txt file copy of the Java code.
I am pretty confident that it is something simple that I have omitted, or did
not realize should be included.
Thank you for your help.
Tom Furst
