Class FacesTilesRequestProcessor

java.lang.Object
  org.apache.struts.action.RequestProcessor
      org.apache.struts.tiles.TilesRequestProcessor
          org.apache.struts.faces.application.FacesTilesRequestProcessor

public class FacesTilesRequestProcessor
extends org.apache.struts.tiles.TilesRequestProcessor

Concrete implementation of RequestProcessor that implements the standard Struts request processing lifecycle on a request that was received as an ActionEvent by our associated ActionListener. It replaces the request processor instance normally configured by Struts+Tiles, so it must support non-Faces requests as well.

Method Detail

doForward

protected void doForward(java.lang.String uri,
                         javax.servlet.http.HttpServletRequest request,
                         javax.servlet.http.HttpServletResponse response)

                         javax.servlet.ServletException

Set up a Faces Request if we are not already processing one. Next, create a new view if the specified uri is different from the current view identifier. Finally, cause the new view to be rendered, and call FacesContext.responseComplete() to indicate that this has already been done.

Overrides:

doForward in class org.apache.struts.tiles.TilesRequestProcessor

Parameters:

uri - Context-relative path to forward to

request - Current page request

response - Current page response

Throws:

java.io.IOException - if an input/output error occurs

javax.servlet.ServletException - if a servlet error occurs

                                throws java.io.IOException

Identify and return the path component (from the request URI for a non-Faces request, or from the form event for a Faces request) that we will use to select an ActionMapping to dispatch with. If no such path can be identified, create an error response and return null.

Overrides:

processPath in class org.apache.struts.action.RequestProcessor

Parameters:

request - The servlet request we are processing

response - The servlet response we are creating

Throws:

processPopulate

protected void processPopulate(javax.servlet.http.HttpServletRequest request,
                               javax.servlet.http.HttpServletResponse response,

Populate the properties of the specified ActionForm instance from the request parameters included with this request, IF this is a non-Faces request.

Overrides:

processPopulate in class org.apache.struts.action.RequestProcessor

Parameters:

request - The servlet request we are processing

response - The servlet response we are creating

form - The ActionForm instance we are populating

mapping - The ActionMapping we are using

Throws:

javax.servlet.ServletException - if thrown by RequestUtils.populate()
