public class TilesView
View implementation that retrieves a Tiles definition. The "url" property is interpreted as name of a Tiles definition.
TilesJstlView with JSTL support is a separate class, mainly to avoid JSTL dependencies in this class.
Depends on a Tiles DefinitionsFactory which must be available in the ServletContext. This factory is typically set up via a TilesConfigurer bean definition in the application context.
A component controller specified in the Tiles definition will receive a reference to the current Spring ApplicationContext if it implements ApplicationContextAware. The ComponentControllerSupport class provides a convenient base class for such Spring-aware component controllers.
