 * <p>Do not forget to register this servlet instance as application listener on the
 * created context (for triggering its {@link #onRefresh callback}, and to call

 * before returning the context instance.
 * @param parent the parent ApplicationContext to use, or {@code null} if none
 * @return the WebApplicationContext for this servlet
