Combined with a practical scientific research item: YZ-ERP for Yueyang Paper Industry Group, it summarizes the management actuality of Yueyang Paper Industry Group, requirements and conceptual design, and puts forward an solution of YZ- ERP based on the J2EE in B/S mode and the realization of YZ- ERP with some related technique.While ERP as the foundation of theory and J2EE as the foundation of technique, the development, trend, some basic concepts and the applications of overseas are first introduced. The J2EE is a kind of structure to simplify the solution of problems, such as the development, deployment and management for the business enterprises. The technologic constitutes, characteristics and principles are studied in this paper.Based on the conceptual design, this paper subdivided the function mold of every subsystems. It delivered the methods to some business process, such as Master Production Planning, Material Requirements Planning, tasks of plants and management of plants' materials and so on. The modeling proceed of database is detailed described. In the part of system's realization, it put great emphasis to discussing the MVC, being a mode of development in software field.

Module, View, Controller and the used technique, such as BC4J, JavaBeans, JSP, JavaScript, CSS, Servlet...etc, are described in details. Finally with an ensample of sale subsystem of YZ- ERP, the operating and realizing processes of the system are present. These analyzed and proved the feasibility and practicability of the MVC mode.
