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
• Expression Language (EL)
All this functionality is available using standard Java APIs and XML-based configuration

In the Java EE 6 platform, new features of JavaServer Faces include the following:
• The ability to use annotations instead of a configuration file to specify managed
beans and other components
• Facelets, a display technology that replaces JavaServer Pages (JSP) technology us-
ing XHTML files
• Ajax support
• Composite components
• Implicit navigation
The Java EE 6 platform requires JavaServer Faces 2.0 and Expression Language 2.2.
