The Research Of Implementing Enterprise Application Framework Of SOA Using J2EE Techonology

Service-Oriented Architecture (SOA) is a new architecture for the development of a new enterprise system and for distributed software development. Because of its good loosely coupled and the platform independently and other characteristics of a good solution to the system's flexibility and interoperability. In the systems based on SOA, specific application function is build up by a number of the components loosely coupled and have a unified interface(that is, service). As enterprise application integration and enterprise solutions to the main structure of the new system, SOA has very wide application. Along with the continuous deepening of enterprise application framework for SOA, the services of IT environment continue to increase. How to create a better SOA framework will be an important research topic.Traditionally, the SOA based on Web Services there is still much deficiency, only have Web Service for building SOA is not enough. If we only develop Web services and issue out these functions is not enough. We also need a correct sequence of these functions together under way, also the safety and performance is the important issue that must be considered. This paper will try to provide a practical service-oriented design method for development of service-oriented enterprise application, making construction of the SOA become well, and improve the capability of SOA.Under the guidance of the basic theory above, based on the classic object-oriented analysis and design (OOAD) and the traditional thinking about layered software architecture, construct the model and architecture based on SOA in the J2EE platform about development of enterprise application in practice, The model consists of five levels of user interface layer, the processing layer, service layer and data access layer and data layer. According to the function of each layer, divide into different services, constitute whole functions of the system and business logic through calling and compositing of services. Finally, we practiced the enterprise application development based on SOA combined with a business case in the J2EE development platform.
