Research And Application Of The Web Composition

In recent years, Web services gradually became the main tool for cross-platform applications, but with the people in-depth understanding of Web services technology, a single Web services, which led to the small size of their services, limited scope of application of this defect gradually exposed, in order to address the deficiencies raised by the trade will be a single Web services portfolio of services to meet the growing needs of enterprises. To this end this paper introduces the service composition language BPEL specification proposes a standard portfolio of services based on this model. The service composition model mainly uses a combination of semi-automatic method, while using convenient service options and dynamic binding technology to enhance their service portfolio flexibility; when the business processes in a Web services where there is an exception, BPEL execution engine can be registered on the UDDI Center query, replace the unusual dynamic Web services, to avoid interruption of business processes. Service composition based on this model and building a service portfolio of business processes through the system validation, we can see in this paper the design process easy Web service composition reuse existing services, reduce unnecessary duplication of function of the preparation of the code, which greatly improves the software production efficiency.
