XAL, initially developed for SNS, is a collection of tools written in pure Java and provides users with a hierarchal view of the accelerator. CSNS makes a lot of changes based on the old XAL. The fringe field is added to online model for accurate calculation of RCS/CSNS and some new database and applications are developed for beam commissioning. The modified XAL framework and example applications will be discussed in this paper. PB - JACoW CP - Geneva, Switzerland ER -
