I, for one, would be very interested in making it easy/possible to uncouple
Jasper from the servlet container itself. The question I have is How much of
a scaffolding is required to use Jasper purely as a template engine without
the baggage of the servlet container per se (or at worst, by being able to
call the _jspservice method with a parameters of (HttpServletRequest,
HttpServletResponse) from within an application instead of over the wire
with http).
Is there anyone who has done this already?
