Adam , This post is old, but I am still facing problems using the watermark, and I need it badly.
I have created a Microsoft word doc file with a watermark and I saved it as a PDF file, and it appears just as I want. Now I am looking for a way for how to do this with PDFBox. You can check this 1 page sample PDF : http://www.4shared.com/document/rQ2berMh/pdf_with_watermark.html Any help would be appreciated.
