Default implementations of each object are provided for cases where the application does not choose to customize the behavior.</p> <p>The instance of <A HREF="../../../javax/faces/application/Application.html" title="class in javax.faces.application"><CODE>Application</CODE></A> is created by calling the <code>getApplication()</code> method of <A HREF="../../../javax/faces/application/ApplicationFactory.html" title="class in javax.faces.application"><CODE>ApplicationFactory</CODE></A>. Because this instance is shared, it must be implemented in a thread-safe manner.</p> <p>The application also acts as a factory for several types of Objects specified in the Faces Configuration file.
