/**
 * Convenience subclass of UrlBasedViewResolver that supports InternalResourceView
 * (i.e. Servlets and JSPs), and subclasses like JstlView and TilesView.
 *
 * The view class for all views generated by this resolver can be specified
 * via setViewClass. See UrlBasedViewResolver's javadocs for details.
 *
 * 
BTW, it's good practice to put JSP files that just serve as views under
 * WEB-INF, to hide them from direct access (e.g. via a manually entered URL).
 * Only controllers will be able to access them then.
 *
 * Note: When chaining ViewResolvers, a InternalResourceViewResolver always
 * needs to be last, as it will attempt to resolve any view name, no matter
 * whether the underlying resource actually exists.
