Bpel4ws-based Portfolio Of Services Technology In The Enterprise Application Integration

With the development of Internet technology, how to implement flexible,convenient Enterprise business information system integration is still a core problem in the information technology field. The traditional Enterprise Application Integration technology can not effectively contact the enterprise background business application with the external enterprise customer dynamically. With the appearance of technology and criterion, for example Web Services, it takes the new progress to Enterprise Application Integration. Enterprise Application Integration has already turned to service oriented integration.At present, Web Services is still a unit of logic program in the internet. It can not integrate with each other very well. So how to break such isolation, integrate each web services and come into being enterprise distributing application system is a very important problem of the web services development. For solving this problem, there is a new development orientation; it is Business Process Execution Language for Web Services, BPEL for short. It wants to be the criterion of web services composition. The development of Enterprise Application Integration based on the Service Composition Technology of BPEL4WS has already become to the mainstream of the development of application system using web services. So the research about how to using the web services composition technology into the enterprise application integration and how to supply a solution framework about using web services to enterprise have practical meaning.This paper base on the BPEL4WS technology, and research how to using it into Enterprise Application Integration. It introduces some conceptions about EAI, development status and some problems. It also describes the basic conception and theory of web services and BPEL4WS, and how to using BPEL4WS technology into the intelligent information system. With the development process of this system, this paper introduces the BPEL4WS technology, and discusses how to using BPEL4WS technology into the J2EE framework from the requirement,high level design,low level design and coding. This paper aims to supplying application pattern for implementing enterprise application integration, using BPEL4WS technology in J2EE field.
