Leonard,
Are you sure? I have tried a few variations and I have not been able to get
anything to work. I now have a simple identity() routine that changes nothing.
The incoming PDF has rights that lets Reader save filled-in data. The
resulting PDF has the rights removed. As far as I can tell, I changed nothing.
What did I do wrong? Here is the code:
public static void identity()
{
PdfReader reader = new PdfReader("C:/tmp/niceForm.pdf");
reader.setAppendable(true);
XfaForm xfaForm = new XfaForm(reader);
FileOutputStream pdfOutput = new FileOutputStream("C:/tmp/newFormOut.pdf");
PdfStamper stamper = new PdfStamper(reader, pdfOutput);
xfaForm.setXfa(stamper.getWriter());
stamper.close();
pdfOutput.close();
reader.close();
}

Subject: Re: [iText-questions] How to change a PDF but preserve the rights
It _IS_ possible to fill in a PDF that has been "Reader Enabled" w/o
violating the rights - but it MUST be done in a very specific fashion using
"append mode" on the source PDF AND only modifying a limited number of objects
in the PDF.
So yes, if you are going to create a whole new PDF - you'll break the "Reader
Enabling". If you're careful about what you do, and how you do it, you CAN
accomplish your goal.

I have a PDF containing an XFA form; isXfaPresent() == true. The PDF was
authored so that it can be opened in Adobe Reader, fields in the form can be
filled, and the form can be saved by Reader to the file system.
Using iText I have read in the PDF, obtained the XfaForm, changed values in
the XML Document, and written a new PDF to the file system.
The PDF I write out contains the values I put into the XML, but the rights
to save the PDF from Reader have been lost. Is this expected? Other features
of the original PDF are also lost in the newly-written PDF.
I wrote the changed PDF to a new file. If this is the reason the save
rights were lost, is there a way I can modify the existing PDF in place so that
the rights to save the file from Adobe Reader are maintained?
