Abstract: This article design the exercise and exam system by applying four-layer open architecture based on J2EE. To reinforce the system’s flexibility and expansibility,several design modes are used to build up the whole architecture and assure the system’s availability and validity. It is proved that J2EE is validated in designing the exercise and exam system’s architecture during the development.
