You're using a fork to eat soup, I mean: you're using AcroForm syntax on 
an XFA form.
Please don't be surprised that this doesn't work.

If you want to set fields to read only, you need to manipulate the XML 
that is embedded in the PDF. You can do this using iText by extracting 
the XML, changing it with the XML library of your choice, and then put 
the XML back into the PDF using iText.

If you want to flatten the fields (removing all interactivity by 
rendering the XFA to PDF), you need XFA Worker:
