Hi Paulo,
I tried it and same exception on below line.
obj_pdfWriter.addAnnotation(signature);
If I do
obj_pdfStamper.addAnnotation(signature, a_iPageNum);
Then null pointer exception occurs as:
//=============================
java.lang.NullPointerException
at com.lowagie.text.pdf.PdfStamperImp.addAnnotation
(PdfStamperImp.java:897)
at com.lowagie.text.pdf.PdfStamperImp.addAnnotation
(PdfStamperImp.java:948)
at com.lowagie.text.pdf.PdfStamper.addAnnotation(PdfStamper.java:375)
//=============================
Can you please send me some sample code to add blank signature field inside
existing PDF.
Regards,
Faisal

That exception says it all. Go to PdfAcroForm.addSignature() source and
copy what's in it. The result will be a PdfAnnotation that you can add
to the doc with obj_pdfStamper.addAnnotation(annot).
