We have many forms that have been Extension Enabled from Adobe Reader Extension Server. Forms were created using Acrobat 5. They are completed (filled-out along with digital sigs) and uploaded by Java app using ENCTYPE="multipart/form-data". We parse Http Request and pull out pdf. Have tried to also include parse of key/value pairs (form data) using FDF toolkit in same upload process without success. Have had success including Submit button on form and extracting form data that way but that's not current workflow. Any suggestions on how to extract form data from upload process?
Use itext (http://www.lowagie.com/iText/)
It's a Java PDF Library.
