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 Detail |

void include(RenderRequest request, RenderResponse response) throws PortletException, IOException
The included servlet cannot set or change the response status code or set headers; any attempt to make a change is ignored.
This method is kept in order to provide backward compatibility with version 1.0. Please use include(PortletRequest, PortletResponse)
instead of this method.
request
- a RenderRequest
object that contains the client request. Must be either the render request passed to the portlet in render
or a wrapped version of this render request.response
- a RenderResponse
object that contains the render response. Must be either the render response passed to the portlet in render
or a wrapped version of this render response.PortletException
- if the included resource throws a ServletException, or other exceptions that are not Runtime- or IOExceptions.IOException
- if the included resource throws this exceptionvoid include(PortletRequest request, PortletResponse response) throws PortletException, IOException
The included servlet cannot set or change the response status code or set headers; any attempt to make a change is ignored.
request
- a PortletRequest
object that contains the portlet request. Must be either the original request passed to the portlet or a wrapped version of this request.response
- a PortletResponse
object that contains the portlet response. Must be either the portlet response passed to the portlet or a wrapped version of this response.PortletException
- if the included resource throws a ServletException, or other exceptions that are not Runtime- or IOExceptions.IOException
- if the included resource throws this exceptionvoid forward(PortletRequest request, PortletResponse response) throws PortletException, IOException
The forward
method should be called before the response has been committed to the portlet container (before response body output has been flushed). If the response already has been committed, this method throws an IllegalStateException
. Uncommitted output in the response buffer is automatically cleared before the forward.
The request and response parameters must be either the same objects as were passed to the calling portlet or be wrapped versions of these.
request
- a request object that represents the request to the portletresponse
- a reponse object that contains the portlet responsePortletException
- if the included resource throws a ServletException, or other exceptions that are not Runtime- or IOExceptions.IOException
- if the included resource throws this exceptionIllegalStateException
- if the response was already committed
