Here is a sample Java program that can load a dynamic XFA form, fill in data from an XDP or XML file and then saved the filled form.

This sample is using Qoppa’s PDF library jPDFFields. It could be simply adapted to use jPDFProcess library by replacing PDFFields with PDFDocument.

import com.qoppa.pdfFields.PDFFields;
public class ImportInXFAForm
    public static void main (String [] args)
            // Load the xfa dynamic form
            PDFFields pdfDoc = new PDFFields ("C:/test/purchase_order.pdf", null);
            // Import the fields data in XDP format
            // Save the filled form 
        catch (Throwable t)

Dynamic Forms have Dynamic Layout
These kind of forms are called dynamic because their layout can change based on the data present in the form. So for instance, when opening the filled XFA dynamic form above in Adobe Reader, one can notice that:

  • the “order” Table has grown and a second page was added to the PDF dynamically to accommodate the size of the table and the number of rows.
  • the Comments field has expanded so the all the imported text from the comments field is visible.

Importing Data
Importing data into an XFA form requires having a valid XDP XML data source that corresponds to that form, instead of an arbitrary XML data source. The difference is that an XDP data source follows the standard required format required for the XML Forms Architecture.
