Can cocoon write pdf to a file?

[kyle koss]

Is it possible for Cocoon to do an XML+XSL -> PDF transformation, but instead of serving the PDF into the browser, writing it to a file?   What I would like to do is, take information entered into a form on a jsp page, turn it into an XML file, and then apply my XSL to it to produce a PDF which is then stored to disk on the server.   Can this be done using Cocoon, or would it be easier to just use FOP embedded in a servlet? If it can be done, what do I have to do?   Regards, Kyle Koss
