Class ResourceServlet

java.lang.Object
javax.servlet.GenericServlet
javax.servlet.http.HttpServlet
org.apache.myfaces.trinidad.webapp.ResourceServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class ResourceServlet

extends javax.servlet.http.HttpServlet

A Servlet which serves up web application resources (images, style sheets, JavaScript libraries) by delegating to a ResourceLoader. The servlet path at which this servlet is registered is used to lookup the class name of the resource loader implementation. For example, if this servlet is registered with name "resources" and URL pattern "/images/*", then its servlet path is "/images". This is used to construct the class loader lookup for the text file "/META-INF/servlets/resources/images.resources" which contains a single line entry with the class name of the resource loader to use. This technique is very similar to "/META-INF/services" lookup that allows the implementation object to implement an interface in the public API and be used by the public API but reside in a private implementation JAR.
