Research On Enterprise Integration Technology Based On J2EE And Web Services

The enterprise information system is more and more important for theenterprise's business today such as financial system, enterprise resource plansystem. Sometimes the enterprise can't effectively work without the supportof the information system. However Because of various reasons, these informationsystems are constructed based on different platforms and different technologieswhich result in the difficulties for the systems to exchange information witheach other. Each system becomes an information island. The situation has hinderedthe development of the enterprise seriously as the enterprise collaboration witheach other closely. Thus the integration of the enterprise systems has becomea major problem for the enterprises. EAI is a solution to this problem.The classic EAI technologies such as the point to point integration can notsolve the problem effectively, the technology based on agents is difficult tomanage and to extend, and furthermore the prices based on these technologiesare very high. How ever the Web services is a simple, flexible, and extensiveintegration technology, it is more and more used to solve integration ofdifferent platform.This paper firstly analyzes the classic EAI technologies such as CORBA,DCOM and their characters, then the Web services structure and its keytechnologies are studied, it has the character of traversing different platformbecause it based on open protocol such as xml,soap. The integrity plan basedon web services is a very good choice for the enterprise.Secondly this paper analyzes the distributed enterprise structureand gives a structure of integration based on web services which is extensibleand widely applicable to the need of integration. Then this paper compares theJ2EE and .NET platform and studies the realization of the web servicesintegration structure based on J2EE. The enterprise integration become easy using the technology plan and can save much time. Finally the order integrationssystem is solved using the web services plan based on J2EE.
