	XAL is an application programming framework initially developed at the Spallation Neutron Source (SNS). It has been employed as a part of control system via con-nection to EPICS to provide application programs for beam commissioning at the China Spallation Neutron Source (CSNS). Several XAL-based applications have been developed for Beam Transport line at CSNS and successfully applied in the MEBT and DTL-1 beam commissioning. These applications will be discussed in this paper.
