Hello list,
I am trying to extend an existing Turbine application by a "Download"
link which should result in a PDF file being served, containing the same
data as in the screen template counterpart.
Take a video database for instance, I can browse through the video
titles and have a look at specific videos by looking at their
"Details.vm" screen template which would output detail information.
Alternatively, I would like to offer a "Download as PDf" link which
should resemble the screen output, but was assembled via FOP, presenting
the video details as a sort of "video data sheet".
With regards to the PDF generation, I am presented with the same
problems as in the course of the template screen generation:
- using the l10n mechanism
- possibly using other pull tools
Therefore it would be very reasonable to use these template services in
a page which does NOT output to the HTTPServlet-request-OutputStream,
but instead is able to
- set a MIME-Type
- gather the output of the template (in which I can use the
beloved set of pull tools, e.g. for internationalization), which
delivers a FO String
- pipe the generated FO String (or Stream) through a FO->PDF
converter
- stream the PDF byte stream into the servlet output
How can I achieve this in Turbine? The FO->PDF conversion poses no
problem (in fact: is already working), but how can I tell Turbine to use
the template mechanism with all pull tools but capturing the output in
order to send it into the FO->PDF converter and stream it back?
I suppose, this has to be a special Page class capable of doing this.
Could you point me in the right direction?
TIA,
Alex
