I didn't hit the links and I'm not sure what you mean by blank but do you set
the server's content type to
something telling your browser it is pdf? If you hit your server with something
more diagnostic than artistic,
like wget instead of IE, you can at least see what it thinks is going on- is
the byte count right etc. You may
even be able to do some diffs and determine if there is truncation or
corruption etc. Also check the servlet
debugging information which you hopefully generate :)
