FDF file import questions

[Harrison Kim <ha...@gmail.com>]

I am in need of filling out a PDF form via FDF file using the command line
on Amazon Linux distro. Is your software capable of doing this?

I had been using PDFtk to accomplish this, but there is no support for
libcgj on amazon linux. Thank you

Please try the ImportFDF.java program in the tools package. Source code 
below. Btw, next time please post to the user mailing list. dev is for 
PDFBox devs.
