There are different ways to submit a form:
- HTML parameters
- FDF
- XFDF
- PDF (only from Adobe Acrobat)

The error message says that you assume that the font submits FDF, but... 
there are three other possibilities. Maybe the form submits XFDF.

Or maybe something is wrong in your Servlet; have you tried writing the 
data sent to the Request to a String. I'm sure it's not an FDF file.
