The view-handler element contains the fully qualified class name
of the concrete ViewHandler implementation class that will be called
during the Restore View and Render Response phases of the request
processing lifecycle. The faces implementation must provide a default
implementation of this class.
To add a view handler:
Select faces-config.xml in the Project Explorer of the J2EE perspective.
The JSF Application Configuration editor opens.
Select the Other tab of the editor.
The Other page appears.
Expand the View Handler section.
The Find Type dialog box appears.
Type the first letter of the type you want to use in the Select a type field.
A list of available types beginning with the letter you typed
appears in the Matching types list.
Select the type that you want to use and click OK.
The view handler is added to the list.
