That sample is somewhat irritating. I would have expected at least one
additional revision after the original signed one but in your case the
signed revision is the last one.
Thus, just to make sure, in your code
LtvVerification v = stamper.getLtvVerification();
AcroFields af = stamper.getAcroFields();
for (String sigName : af.getSignatureNames()) {
[...]
}
v.merge();
which PdfStamper stamper do you work on? Is it the PdfStamper you retrieved
to create the signature with or is it a stamper you opened for the already
signed file?
Using that code on the PdfStamper you create the original signature with
won't work because the code adds validation related information for already
existing signatures only.
If you used that code on a PdfStamper working on a PdfReader containing the
PDF already containing the original signature, please post more of the code
doing that...
Regards, Michael
