in the distributed application. This folder should not contain any test code, such

All source will be contained within the org.apache.ibatis.jgamestore base pack-
age. Each package beneath the base package categorizes components of the appli-
The subpackages will be as follows:
domain —This package will contain DTO/POJO classes that are the transient
objects in the application. These objects will be passed among and used by
