iText, Flying Saucer, and Lotus Domino agent

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: 06/30/2009 03:37:21 PM HTTP JVM: Jun 30, 2009 3:37:08 PM org.xhtmlrenderer.util.XRLog log INFO: Using CSS implementation from: org.xhtmlrenderer.context.StyleReference 06/30/2009 03:37:21 PM HTTP JVM: Jun 30, 2009 3:37:08 PM org.xhtmlrenderer.util.XRLog log WARNING: Could not parse default stylesheet java.lang.NullPointerException at org.xhtmlrenderer.simple.extend.XhtmlCssOnlyNamespaceHandler.getDefaultStylesheetStream(XhtmlCssOnlyNamespaceHandler.java:407) at org.xhtmlrenderer.simple.extend.XhtmlCssOnlyNamespaceHandler.getDefaultStylesheet(XhtmlCssOnlyNamespaceHandler.java:372) at org.xhtmlrenderer.context.StyleReference.getStylesheets(StyleReference.java:242) 06/30/2009 03:37:21 PM HTTP JVM: Jun 30, 2009 3:37:09 PM org.xhtmlrenderer.util.XRLog log INFO: TIME: parse stylesheets 156ms 06/30/2009 03:37:21 PM HTTP JVM: Jun 30, 2009 3:37:09 PM org.xhtmlrenderer.util.XRLog log INFO: media = print 06/30/2009 03:37:21 PM HTTP JVM: Jun 30, 2009 3:37:09 PM org.xhtmlrenderer.util.XRLog log INFO: Requesting stylesheet: http://www.w3.org/1999/xhtml 06/30/2009 03:37:22 PM HTTP JVM: Jun 30, 2009 3:37:09 PM org.xhtmlrenderer.util.XRLog log WARNING: (http://www.w3.org/1999/xhtml) Found < (other) where one of a hex color, ., [, or : was expected at line 1.

Sorry, but it's virtually impossible to help from this mailing list. FS wraps iText in its own classes. You'll need to pursue this with them.
