I thought of sharing some interesting information regarding XFA Forms and places where consideration has to be taken when you attempt to convert XFA forms into Java based swing components. Please read this article on XFA Components and Structure to help grasp the basic structure of XFA.
1. TextEdit field in XFA:
The XFA Text Edit field behaves very similar to the JTextField in swing, At the same time TextEdit may also function as swing text area. “MultiLine” attribute in TextEdit node decides whether the text field has to be text area or not. As I mentioned in my previous article on XFA structure, Field objects can also be designed to be dynamic. Dynamically designed TextField’s height is expandable to room data contents.
2. Other TextFields
XFA forms contains NumericEdit, DateTimeEdit, PasswordEdit and customized text components in addition to TextEdit, These components can be built using the same JTextField in swing and regular expressions need to be used to ensure data input.
3. Radio Buttons
Unlike swing radio buttons the appearance of XFA radio buttons can be either round or box, It is worth investigating “ExclGroup” tag before deciding swing form allocation. (Ususally radio buttons are created inside ExclGroup tag). Name of ExclGroup can be utilized to name the group of radio buttons if it accommodated under ExclGroup.
Most of the field components may have a caption which acts as JLabel but is a part of Form. The location of caption is not stick to one place and may vary.
6. ImageEdit (Image Field) and Signature field
Both the fields mentioned above act similar to file upload in Swing.
I believe this information may useful for you prior to making any design decisions from XFA to swing components.

IDRsolutions develop a Java PDF library, a PDF forms to HTML5 converter, a PDF to HTML5 or SVG converter and a Java Image Library that doubles as an ImageIO replacement. On the blog our team post about anything interesting they learn about.
