[iText-questions] iText, Flying Saucer, and Lotus Domino agent

Tue, 30 Jun 2009 20:54:24 -0700

I am trying to convert HTML to PDF using Flying Saucer. I need to be able to use style sheet to do positioning, set font size, color, etc. From what I have searched so far, the FS is the best way to do that. I can't find a discussion forum that I can post a question to on their site, so that's why I am posting a question here. Hopefully, someone can help me here.
 
I have taken the sample code (the 99 bottles of beer) from this article:
http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer-and-itext.html
 
I got it to work in Eclipse. However, my ultimate goal is to port the code into a Lotus Domino java agent. When I do that, I get the error below. The PDF is created, but it completely ignores the CSS. It treats the style as text and it is shown as plain text on the PDF. I tried using an external style sheet, but the result is the same.
I appreciate any advice you can give me. Thanks.
 
Here's the error:
