public class ResourceServlet

extends HttpServletBean

Simple servlet that can expose an internal resource, including a default URL if the specified resource is not found. An alternative, for example, to trying and catching exceptions when using JSP include.

A typical usage would map all URLs with a .res extension onto an instanceof this servlet, and use the JSP include action to include with the resource parameter (specificed in a jsp:param sub-action) indicating the actual path in the WAR.

The defaultUrl bean property must be set to the internal path of the default (placeholder) URL.
