public interface: PortletRequestDispatcher [javadoc | source] The PortletRequestDispatcher interface defines an object that receives requests from the client and sends them to the specified resources (such as a servlet, HTML file, or JSP file) on the server. The portlet container creates the PortletRequestDispatcher object, which is used as a wrapper around a server resource located at a particular path or given by a particular name.
