Based On The J2ee Architecture Of Ofbiz Technology Research And Application Of The B / S System

The development of internet has pushed the wide use of Web. As more and more computer systems apply B/S framework. It is becoming harder and harder for the simple J2EE framework to fulfill some large-scale systems that perform complicated programs. Thus operating framework like OFBiz which formed by taking the technological framework as the fulcrum has got widely application.OFBiz (Open For Business) is a famous open source project which provide the framework that the framework is used to build the Web application, which is based on the newest rule and technique standard of J2EE/XML and construct large or middle scale distributed multi-tier Web applications, which is platform-independent, and can be deployed across different databases and application servers.This thesis gives a general profile of J2EE at the beginning, enlightening the reader the functions of separate parts and the relations between the different parts. And based on the J2EE, this thesis analyzes thoroughly the present multi-division of B/S framework, putting forward the opinion of separately designing each layer of the five layers of B/S framework, discussing the main technologies that can be applied to each layer. Then studys the technical idea and concept of OFBiz and several key technologies of this framework. After that based on the plan of designing five layers separately and demand analysis of investing risk management system, this thesis design a set of framework that applicable to this system and explain every layer of this framework. Finally combining the characteristics of OFBiz framework, this thesis expatiates the executive progress of the above-mentioned investing risk management system. During the process of executing the system, the technical characteristics and advantages of OFBiz have been fully showed. OFBiz offered an ideal basic framework on which development based. This system makes it possible for the developer to customize abide by their request and this system is also easy to be assembled and is friendly used.
