Description copied from interface: PortletRequestDispatcher

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.

Specified by:

include in interface PortletRequestDispatcher

Parameters:

req - a RenderRequest object that contains the client request

resp - 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
