I got the solution. Problem was below:

When getting an object of 'PdfStamper', two different constructors are
provided.
  (Method-1)   obj_pdfStamper = new PdfStamper(obj_pdfReader, obj_fos);
  (Method-2)   obj_pdfStamper = new PdfStamper(obj_pdfReader, obj_fos,
obj_pdfReader.getPdfVersion(), true);

In a PDF form if there are multiple interactive fields with same name then
these are of one group.
If field is a check box, I was updating the values using the following code
with perticular field dictionary.

  pdfDic.put(PdfName.AS, new PdfName(str_newValue));

I noticed that when I was using (Method-1), new value was not saved while by
using (Method-2), new value was saved.

But problem to follow (Method-2) is that it corrupted the already signed PDF
signatures.

Now I am using following way and there seems to be no problem:

  obj_pdfStamper.getAcroFields().setField(str_fieldName, str_newValue);

Faisal
