Check whether controller is null or whether getKelompokBiayaJpaController() method returns null. Based on your error message (I presume that you showed the root cause correctly) the controller object is null. So you have to find out why either MasterBiyanMbean is not present or why fetching the object does not work. Very basic stuff (null checks and all).
