If i do this, Acrobat reader does not validate the signature. Maybe I'm
missing something. The problem sounds like

You generate the hash on the server. You send the hash to the client
to be signed (since that;s the data actually being signed). The
"signed data & cert" are sent back to the server where iText can
embed it into the PDF. It's not unlike the existin
Sorry, the PDF lives on the server. Both unsigned and signed files should be
on the server. The certificate is on the client computer.. smartcard, p12..
We want an applet to do the signing job for example. But keeping objects and
files open on the server waiting for the signature is not an option.
So the PDF lives on the client computer or the server? Where does
the user's certificate live - desktop or server?
And why would there a delay between the two operations?

Consider the following scenario. A hash is computed, as indicated in the
