Render Page to file, etc
I have a need to make my Tapestry 4.1 Pages available in pdf format but
having no luck to-date on my own.
My apologies if soliciting this list is inappropriate here, but I do have a
consulting budget available to get this done if anyone is interested.

#1 is the real trick. The way I finally got a working implementation was to
simply establish an HttpSession to Tapestry to call up the Page requested.
Basically mimicing a web browser. I can then capture the OutputStream that
way and convert to String, etc for rendering to pdf.
There's extra overhead, plus special account handling for this "worker"
session since the Tapestry application is user restricted, but it works.
Time permitting, I'll investigate the blog you reference since it might be a
cleaner solution.
Thanks for the pointers!

The process should be:
1) render the page to a String, perhaps
http://www.behindthesite.com/blog/C1931765677/E2094832857/index.html can help
2) convert the html String to pdf, see
http://www.javaworld.com/javaworld/jw-04-2006/jw-0410-html.html and/or
http://codedeliver.blogspot.com/2009/07/converting-xhtml-html-to-pdf-with-css.html
So, it's possible to create a Tapestry service that will do the above
and write the pdf
to the output stream... or, perhaps even better, write a ServletFilter
that swaps the
response stream with its own, forwards to the Tapestry servlet and
when that returns
does the post-processing (of converting the contents of its internal
stream from html to
pdf)
