Ah - now I see the problem (or at least I think I do).

I suspect that you are using Adobe Reader, and not Adobe Acrobat, as  
your PDF viewer.  And you are expecting to be able to add comments,  
digitally sign, etc.   HOWEVER, Adobe Reader does NOT support such  
operations on a normal PDF (as you have).  In order to gain such  
rights, you must ADD THEM to the PDF using an Adobe application (such  
as Acrobat or LiveCycle).  It is not possible to add them with iText  
or other 3rd party solutions.
