ZK has the following characteristics.
- XUL-based Components. Over 55 feature-rich XUL components are supported. No proprietary components.
- Event Driven Model. Simple and intuitive as what we enjoyed in developing desktop apps.
- Representation in XUL. No programming knowledge required. Leveraging XUL community and resources.
- Script in Java and EL Expressions. Quick prototyping and customization. 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.
