[seam-dev] Let me know what you need for a first stab at the PDF/Mail port from Seam 2

Sat May 22 17:29:31 EDT 2010

In Seam 2 there was the DocumentServlet that Excel and PDF output used for
content delivery (conversation scoped, generate data and redirect). Is there
any need for this step? And if so, should we use JSF 2 resource handling for
it?

I played around with mojarra 2 examined it for possibilities of loosening
the servlet dependencies but it turned out the ServletContext was used about
everywhere internally.
