You have created a PDF with signature fields like this:

But somehow you've missed the example that follows right
after the one mentioned above:
http://1t3xt.info/examples/browse/?page=example&id=252
And if you need two signatures, you'll need to read even
further and have a look at:
http://1t3xt.info/examples/browse/?page=example&id=253
Especially where it says:
PdfStamper stamper = PdfStamper.createSignature(reader,
os, '\0', null, true);
Otherwise the second signature will invalidate the first one.
