Hi,
can you try this piece of code
                FacesContext facesCtx = FacesContext.getCurrentInstance();
                ExternalContext ctx = FacesContext.getCurrentInstance().getExternalContext();
                String viewId = "Logout.jspx";
                ControllerContext controllerCtx = null;
                controllerCtx = ControllerContext.getInstance();
                String activityURL = controllerCtx.getGlobalViewActivityURL(viewId);
                System.out.println(":::: Current Activity URL ::" + activityURL);
                try {
                    session.invalidate();
                    ctx.redirect(activityURL);
                } catch (IOException e) {
                    log.error("error in trying to redirect to login page  " + e);
                    e.printStackTrace();
                }~Abhijit
