In JSFUtils there is a getPageURL method. it will give the whole URL of your page. you can play with the URL string to get the part you need.
   * Method to create a redirect URL. The assumption is that the JSF servlet mapping is
   * "faces", which is the default
   * @param view the JSP or JSPX page to redirect to
   * @return a URL to redirect to
  public static String getPageURL(String view)
    FacesContext facesContext = getFacesContext();
    ExternalContext externalContext = facesContext.getExternalContext();
    String url =
      ((HttpServletRequest) externalContext.getRequest()).getRequestURL().toString();
    StringBuffer newUrlBuffer = new StringBuffer();
    newUrlBuffer.append(url.substring(0, url.lastIndexOf("faces/")));
    newUrlBuffer.append("faces");
    String targetPageUrl = view.startsWith("/")? view: "/" + view;
    newUrlBuffer.append(targetPageUrl);
    return newUrlBuffer.toString();
  }
