Interface PortletRequestDispatcher

All Known Implementing Classes:: PortletRequestDispatcherImpl

public interface PortletRequestDispatcher

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.

Method Summary

void include(RenderRequest request, RenderResponse response)
Includes the content of a resource (servlet, JSP page, HTML file) in the response.

Method Detail

include

public void include(RenderRequest request,
                    RenderResponse response)
             throws PortletException,
                    java.io.IOException

Includes the content of a resource (servlet, JSP page, HTML file) in the response. In essence, this method enables programmatic server-side includes.

The included servlet cannot set or change the response status code or set headers; any attempt to make a change is ignored.

Parameters:: request - a RenderRequest object that contains the client request; response - a RenderResponse object that contains the render response
Throws:: PortletException - if the included resource throws a ServletException, or other exceptions that are not Runtime- or IOExceptions.; java.io.IOException - if the included resource throws this exception
