Populating Component Tree Values from Servlet

[Elam Daly]

Hi all,

I got the code below from the JSF spec, and it works fine except for the fact that I don't know how to put values recieved from the query string of a servlet into my Managed beans so that they are displayed when the first page initially comes up.  In fact, I can't get a childCount from the UIViewRoot component till after the call to lifecycle.render(), which calls the render response phase, which is the last phase in the cycle.

Any help is much appreciated.

public class RedirectServlet extends HttpServlet {

       protected void doGet( HttpServletRequest request, HttpServletResponse response) {
          
LifecycleFactory lifecycleFactory = (LifecycleFactory) FactoryFinder.getFactory(
                       FactoryFinder.LIFECYCLE_FACTORY);
           Lifecycle lifecycle = lifecycleFactory.getLifecycle(
                   LifecycleFactory.DEFAULT_LIFECYCLE);

           FacesContextFactory facesContextFactory =
               (FacesContextFactory) FactoryFinder.getFactory(
                       FactoryFinder.FACES_CONTEXT_FACTORY);
           FacesContext facesCtx = facesContextFactory.getFacesContext( getServletContext(),
                   request, response, lifecycle);
          
                      // Create new view

                      // 2.4.2.1
           Application app = facesCtx.getApplication();
           ViewHandler viewHdlr = app.getViewHandler();
           UIViewRoot viewRoot = viewHdlr.createView( facesCtx, requestedView);
                      // 2.4.2.2: we accept the default renderkit
                      // 2.4.2.3: we'll let Faces handle the
                      //   component tree

                      // 2.4.2.4: store view into context
           facesCtx.setViewRoot( viewRoot);
           lifecycle.render( facesCtx);
