I will contact them (PDFTron) as well, and see if they can help. > > > I missed the earlier posts but in response to this, I would just reiterate that if you go get pdfrenderer the open source java app, not only do you get a usable opensource viewwer, it is trivial to rwrite a command line app to dump your pdf as a series of images or do whatever else you can do in JAI etc. If you are really stuck and need something which can render pdf that is more suited to your needs, at least for the front end. When you want to author a pdf in an automated way ( talk about an oxymoron LOL), that seems to be better suited to itext.
