Open Source XML UI Toolkits in Java

CookSwing is a library which builds Java Swing GUI from XML documents. It supports all Swing components, all Swing LayoutManager (including JGoodies Forms layout), all listeners, all Swing borders (including compound borders), and internationalization and localization. XML include for templated UI layout is supported as well. CookSwing also goes beyond merely Swing since many Swing components require fairly complex configuration parameters. Java binding with components generated by CookSwing is very easy. One of the primary strength CookSwing over other XUL toolkit is being easily extensible. It has a modular design and offers great debugging capabilities. CookSwing is also well documented with its innovative tagdoc, and having lots of examples and demos.
