Thanks Michael. I read through the forums and was planning to use the "reuse
the stamper" approach. Unfortunately, though neither the stamper nor the
signature appearance objects are serializable and therefore can't be stored
in my HTTP session for reuse.
I've tried to find the sample implmentation for the "compromise" approach
you said Andreas had done but haven't had any luck finding it. I could use
some help either finding this code or with a bit more information on how it
works so that I can attempt it myself.
Specifically, I'm not sure how to "insert that signature manually".
Thanks again for the help.
