Tapestry and PDF

I was wondering if anyone used Tapestry with PDF generation frameworks? 
SourceForge mailing lists are really "searchable", so I can't tell if this 
was discussed in the past.

Anyway, just checking what potential problems I might have.

PDF generation is a part of a bigger Cayenne/Tapestry application. We are 
using iText as PDF generation framework. It seems to be more solid than 
things like FOP.

Tapestry PDF pages override "beginResponse" to set the right HTTP headers 
and push the PDF content directly to HttpServletResponse. Unfortunately 
this brings Tapestry down to simple servlet API. And using iText XML 
options (with XML generated by Tapestry, and then fed to PDF generator) 
seem like big performance overhead. Anyone has any experience with such setup?

Thanks
Andrus
