mandar.jagtap,
Here is some code I wrote based on the iText examples.
I am pretty sure if you use PdfReader and PdfStamper you will keep all your
bookmarks, etc.
but you have to extract them from the reader and add them to the stamper.
I have tested this with success on PDFs rendered from FOP, Word Perfect, and
XSL Formatter.
All links and bookmarks are retained. (code below)
Anyway, I modified code I found in the iText examples and read the portions in
the iText book.
My intention here was to add Metadata tags to the PDF.
All you need is to extract the dictionary from the reader [ reader.getInfo() ]
then put it back into the stamper [stp.setMoreInfo() ] .
Sincerely,
-mike

No, but there are alternatives.

It's a bug that could be easily fixed.
