Hello,
You are right, only using overcontent did the trick and my
header/footers are now appearing on every page.
Thank you guys for your efficient help.
I am guilty of copy/pasting googled examples without a good
understanding of the whole thing.
I will stick to your advices, clean up my code, use a newer version,
and invest more time to understand concepts and good practises.
Regards

Hello,
Below is a method to add headers and footers to an existing document.
Please remove all references to Document and PdfCopy (to start with).
There are other problems in your code; most of them can be solved by
cleaning up your code.
It works fine on most document but sometimes, on some pages,
especially if they seem to have been scanned, the header/footer is
not displayed.
It seems to be here because a selection on something invisible can be
performed. There must be a foreground/background issue there but I
was unable to find any clue to make sure the my header/footer are
guaranteed to appear.
You're using a very old version of iText:
import com.lowagie.text.*;
Recent versions use com.itextpdf.text.*
Recent versions contain plenty of bug fixes.
You should upgrade!
You don't need a Document, do you?
Document underdocument = null;
Document overdocument = null;
You only need a PdfStamper and a PdfReader:
PdfStamper pdfstamper = null;
PdfReader reader;
Why do you need undercontent?
Remove:
PdfContentByte undercontent ;
Keep:
PdfContentByte overcontent ;
This is wrong:
underdocument = undercontent.getPdfDocument();
overdocument = overcontent.getPdfDocument();
You need to get the MediaBox or CropBox from the PdfReader object,
NOT from the Document object!
This is also wrong:
fret = pdffooter.writeSelectedRows(0, -1, 0,
underdocument.bottom(), undercontent);
Seems like your adding the footer under the visible area of the page.
Also: add the content on top of the existing content, not under it
(replace undercontent with overcontent).
