/**
* AbstractApplicationBean is the abstract base class for
* data bean(s) that are stored in application scope attributes. It extends
* {@link AbstractFacesBean}, so it inherits all of the default behavior
* found there. In addition, the following lifecycle methods are called
* automatically when the corresponding events occur:
*
* init() - Called when this bean is initially added as an
* application scope attribute (typically as the result of
* evaluating a value binding or method binding expression).destroy() - Called when the bean is removed from the
* application attributes (typically as a result of the application
* being shut down by the servlet container).
