Research On The Construction Of SOA Platform Based On J2EE

In the process of enterprise informationization,a great deal of information islands has been formed because of the lack of overall planning in the development of IS.As the time of E-Commerce has now come,traditional complex systems can not adapt the fast changing of requirements.So a more effective and flexible integration model is needed for the demand of E-Commerce.The conception of SOA is more and more widely researched and used with the developing of distributed software and middleware technology.Its goal is to provide a smart and unlimited integration environment to realize the most reuse of enterprise IT assets.This paper firstly introduces the development of Java network applications as well as relevant web technologies on the basis of Java language,and then elaborates the famous J2EE platform.On the basis of this,the paper makes a study and analysis about SOA's features and essentials for implementation.Web Service and ESB are introduced,which support the implementation of SOA.Later,this paper analyses the mechanism of JWSDP,JAX-RPC and JAXR.After this,a J2EE model with 4 layers is put forward,which reformed J2EE by using SOA conception and realized Web Service standards.The system can be easily adjusted when the requirement changes.Finally,this paper designs the system of a home appliance shop online and separates it into 3 independent parts according the needs of both actors and business. Then this paper makes a detailed design of the system with Struts and gets it implemented by using Websphere server and Services Integration Bus.The structure of the system with SOA used on it is proved to have good agility and ability to adapt the environment.
