PDF document generation from gwt pages

This is more of a best practice question and seeing what solutions exist out there. We use gwt as our web framework to show custom/dynamic reports on the web, and we are always asked to provide a PDF version of the report. In the past we have used HTML unit to scrap the generated HTML page that gwt renders and do an HTML to PDF transformation on the server side using a licensed third party tool. Anyone in this group had to face this issue? Any recommendations? Using a unit test framework to solve this production problem does not seem legit.

Thanks in advance,
