1. Read the documentation of ServletResponse.getOutputStream() - _first_
call setContentType(), then obtain output writer/stream - otherwise
incorrect results my occur (setContentType() may modify the type of
Writer class returned...)
2. Try to set the filename in the contenttype header - the "attachment;
filename" method normally appiles to emails only (or not ??)...
