All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

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 instance of 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.
