Bpel Service Composition Technology In The Logistics System Design And Realization

Web services technologies has been completed the stage of infrastructure development and the concept promotion. Now it is a massive business applicat-ions developed rapidly, but because of lack of coordination mechanism on the internet, it become isolated logical unit of data, and cannot effectively integrate d. how to break through the isolation, integrate effectively commercial applicat-ion, reuse existing web service, and generate new services through controllable and automate way to combinate services to meet enterprise need of dynamic, which has become a Web Service technology evolving extensions momentum of development and research hotspot.Application SOA (Service-Oriented Architecture) framework is an efficient way of constructing loose coupling Web service composition system, SOA is design oriented service, instead of the traditional technical architecture design. This thesis is concentrated on exploring the Web service composition technolo-gy application in SOA architecture, and based on logistics information platform as a background, based on the SOA as thought frame, on the basis of Web service, putting forward a kind of BPEL service composition mechanism design mode, in order to improve the service reusability and reduce software develop-ment costs. First, this paper introduces briefly the main Web service technology, Web service design and description:to Web service as a Server Publishing, se-rvice registration, service search technology, all the functions are defined as in-dependent service, which is fine granularity, loose coupling, heterogeneous, and all fine granularity services are integrated into the enterprise service bus ESB, which provide Unified platform with monitoring and management; Then, puts f orward the design of BPEL service Composition mechanisms:To a fine granul arity Web service as basis components, integrating it with BPEL Service Com-position technology. Using WS-BPEL process designer design CarSheetAccountb usiness process, configurate artificially static port address of service invoked, so that can execute dynamic orderly business process of on-demand orchestra-tion. and some fine granularity service are integrated coarse granularity service; Finally, accomplish the publishing and testing of CarSheetAccount process in logistics system:test, monitor and manage all of the process by the WS02-BPS platform, meanwhile, process is published as a service, which make calls quick flexible and return timely information for external users. In the cases of without rewriting the code, application of BPEL technology can form business process of enterprise flexible application, and approach business process config-urable, service reusable effect.
