Examples of javax.faces.application.Application

javax.faces.application.Application

Application represents a per-web-application singleton object where applications based on JavaServer Faces (or implementations wishing to provide extended functionality) can register application-wide singletons that provide functionality required by JavaServer Faces. Default implementations of each object are provided for cases where the application does not choose to customize the behavior.

The instance of {@link Application} is created by calling thegetApplication() method of {@link ApplicationFactory}. Because this instance is shared, it must be implemented in a thread-safe manner.

The application also acts as a factory for several types of Objects specified in the Faces Configuration file. Please see {@link Application#createComponent}, {@link Application#createConverter}, and {@link Application#createValidator}.
