Thanks very muich Bruno for your clarification. In fact, it is a long
time since I reviwed the Tutorials - hence I reviwed them again.
I reviwed the code once again and found a glitch. Modified the line
PdfWriter writer = PdfWriter.getInstance(doc, new
FileOutputStream("HTRSCertificates.pdf"));
to
PdfWriter writer = PdfWriter.getInstance(doc.baos);
the code works now.
Thanks a million to everyone who helped me in this.

I just arrived from work and I have difficulties following the track
of the question/answers. The way you put your answer is also not
very inviting to answer.
This being said, I see that you create a Document object doc and
a PdfWriter that writes to a FileOutputStream. Then you CLOSE
the document.
That finalizes the PDF Creation. You're done. Case closed.
Surprisingly you then reuse the Document instance doc to do something
else with it. Why do you expect this to work? It proves you didn't
read
(or didn't understand) the tutorial, more specifically the part about
the
5 steps in PDF creation with iText.

Bruno
