It is similar to the programming model found in desktop GUI-based applications.feature- richXULXHTML

3. What is ZK?  ZK takes the so called server-centric approach  licensed under the GPL (GNU Public License).  ZK's AJAX engine consists of both client and server components that communicate with one another.  ZK provides two sets of user interface components.

4. What is ZK?  ZK supports a markup language for rich user interface definition called ZUML.  ZUML (ZK User Interface Markup Language) is a markup language for rich user interfaces definition.  ZUML is designed for non-programmer developers to design user interfaces intuitively.  ZUML allows developer to meld different markup languages, such as Mozilla XUL language and XHTML, seamlessly into the same pageMozilla
