Which two are significant advantages of developing web applications with JavaServer Faces (JSF)?
A. JSF pages can be previewed outside the web container.
B. Backing beans can be unit tested outside the web container.
C. Client-side validation mechanisms are automatically generated.
D. JSF pages can be integrated with AJAX.
Correct Answer: CD
Explanation/Reference:
Explanation: D: JSF is often used together with Ajax, a Rich Internet application technology. Because JSF supports multiple output formats, Ajaxenabled components can easily be added to enrich JSF-based user interfaces. The JSF 2.0 specification provides built in support for Ajax by standardizing the Ajax request lifecycle, and providing simple development interfaces to Ajax events, allowing any event triggered by the client to go through proper validation, conversion, and finally method invocation, before returning the result to the browser via an XML DOM update.
Note:
* JavaServer Faces technology is a user interface framework for building web applications.
* The following features support the GUI components:
/ Input validation
/ Event handling
/ Data conversion between model objects and components / Managed model object creation
/ Page navigation configuration
All this functionality is available using standard Java APIs and XML-based configuration files.
