AJAX to your applications.

• No other solution allows you to combine the full power of JSF with a modern Web

2.0 interface.

• No other solution has such openness, such full compatibility with all standard JSF

implementations and component libraries.

• No other solution gives you such flexibility in look and feel.

• No other solution gives you this level of power to deliver results.
