    Webflow integration

    eoin81 Newbie

      Hi,

       

      In Webflow 2.0.6 the integration point with RichFaces 3.3.3 was :

       

      <bean class="org.springframework.webflow.mvc.servlet.FlowHandlerAdapter">  

      <property name="ajaxHandler">

              <bean class="org.springframework.faces.richfaces.RichFacesAjaxHandler"/>                       

          </property>

      </bean>

       

      RichFacesAjaxHandler then uses org.ajax4jsf.context.AjaxContext in it's implementation.

       

      Upgrading to RichFaces 4.0.0 org.ajax4jsf.context.AjaxContext is not available.

       

      Is there a way around this? Thanks!

          Looks like this class (org.ajax4jsf.context.AjaxContext) was available in 4.X.Alpha2 (richfaces-core-api) but was not released in 4.X.Final.

           

          Was there any reason for this?

            Hi,

             

            Yes, this is a legacy class. org.richfaces.context.ExtendedPartialViewContext replaced it.

              Thanks for the clarification Nick.

               

              Spring-Faces (latest version 2.3) still references this legecy class.

               

              So i guess Integration between RichFaces 4.0.0.Final & Webflow wont be possible yet?

                That's an extension over standard PartialViewContext of JSF 2. I haven't yet checked how SWF implements integration with JSF 2, need to try that.

                 

                I've created JIRA issue to cover that: https://issues.jboss.org/browse/RFPL-1430

                  Thanks Nick.

                  I'd be interested in the outcome.

                    Hello,

                     

                    RichFacesAjaxHandler is no longer needed for RichFaces 4.0 / JSF 2.

                     

                    You can see JIRA issue which covers integration for details.

                      Hi Guys, Thanks a lot for the work on this.

                       

                      I followed the steps outlined in the JIRA issue...

                       

                      I attached the richfacesResourceHandler to the SimpleUrlHandlerMapping in my web-mvc-config.xml and that seems to work (I can see the trace output that maps the /rfRes/**=richfacesResourceHandler to the SimpleUrlHandlerMapping in the logs).

                       

                      However in Firebug (net tab) I get a bunch of 404 errors when rich faces looks for external resources (for example: **/rfRes/skinning.ecss.html?db=eAHL6rC8BQAEkAIG).

                       

                      My config looks the same (but obviously not the exact same!!) as the prototype (but I have some extra things in web xml like filters etc...).

                       

                      Do I need anything else to map the requests to resources successfully?

                        Forget that guys.

                         

                        In my web xml I map requests from: <url-pattern>/test.html/*</url-pattern> to the dispatcher servler.

                         

                        Which confuses the mappings I have registered above for /rfRes/**=richfacesResourceHandler resulting in 404 errors for all requests to rich faces external resources ....

                         

                        Editing my url pattern to <url-pattern>/test/*</url-pattern> works fine but not sure why the above is causing issues!

                          I have tried also following dispatcher servlet mapping and that worked for me without problem with resources:

                           

                           

                          <servlet-mapping>
                                              <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
                                              <url-pattern>/spring/*</url-pattern>
                                    </servlet-mapping>

                            Hi Lukáš

                             

                            This works fine:

                             

                            <servlet>
                                    <servlet-name>DispatcherServlet</servlet-name>
                                    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                                    <init-param>
                                        <param-name>contextConfigLocation</param-name>
                                        <param-value>
                                            /WEB-INF/config/web-application-config.xml                
                                        </param-value>
                                    </init-param>
                                    <load-on-startup>1</load-on-startup>
                                </servlet>
                            
                                <servlet-mapping>
                                    <servlet-name>DispatcherServlet</servlet-name>
                                    <url-pattern>/test/*</url-pattern>
                                </servlet-mapping>
                            

                             

                            This dosent work:

                                    <servlet-name>DispatcherServlet</servlet-name>

                                    <init-param>
                                        <param-name>contextConfigLocation</param-name>
                                        <param-value>
                                            /WEB-INF/config/web-application-config.xml                
                                        </param-value>
                                    </init-param>
                                    <load-on-startup>1</load-on-startup>
                                </servlet>
                            
                                <servlet-mapping>
                                    <servlet-name>DispatcherServlet</servlet-name>
                                    <url-pattern>/test.html/*</url-pattern>
                                </servlet-mapping>
                            
                            
                            

                             

                             

                            By not working I mean, with the second mapping above, requests to external rich faces resources are not found (404).
