    Moving JSF 1.1 application to 1.2

    Matt Choate Newbie

      We are trying to move our application from a JSF 1.1 based AS to a JSF 1.2 AS. In our current implementation we have the pattern where a XMLHttp browser request is made to a servlet which will try to reference the FacesContext in the service() method. This all worked under 1.1 just fine but when we deploy this to a 1.2 based server we get stack traces like:

      This happens in every instance where we try to reference managed beans in a servlet. Oh, and we are getting the FacesContext following this approach:

      LifecycleFactory lifecycleFactory = (LifecycleFactory)
      FactoryFinder.getFactory(FactoryFinder.LIFECYCLE_FACTORY);
      Lifecycle lifecycle = lifecycleFactory.getLifecycle(LifecycleFactory.DEFAULT_LIFECYCLE);

      // Create new FacesContext.
      FacesContextFactory contextFactory = (FacesContextFactory)
      FactoryFinder.getFactory(FactoryFinder.FACES_CONTEXT_FACTORY);
      facesContext = contextFactory.getFacesContext(
      request.getSession().getServletContext(), request, response, lifecycle);

      // Create new View.
      UIViewRoot view = facesContext.getApplication().getViewHandler().createView(
      facesContext, "");
      facesContext.setViewRoot(view);

      // Set current FacesContext.
      FacesContextWrapper.setCurrentInstance(facesContext);


      Anyhelp or advice would be most appreciated!
