ZK is an AJAX-based, event-driven, XUL-compliant, all Java framework to enable rich user interfaces for Web applications. With ZK, you represent your Web application in feature-rich in XUL and HTML components, and manipulate these components by listening to events triggered by users, all at the server, as simple and rich as you did for years in desktop applications.
No JavaScript and AJAX for application developers. No need to replicate business logic at the clients. No proprietary components. No compilation. Just manipulate in a markup language, ZUL, deriving from XUL. Just POJO (Plain Old Java cOdes). ZK works with existent frameworks and technologies, such as JSF and Portals, so the pace of adapting it is all under your control. It is GPL. More details are available at http://zk1.sourceforge.net. You could try the features online without installation at http://www.potix.com/zkdemo/userguide. Welcome your input. Please forward to anyone who might be interested. Thanks and Regards, Tom Yeh The ZK project
