Research on Dynamic Web Services Composition Based on BPEL and QoS
Shi Weifeng · Computer Technology and Development · 2009
By using BPEL,Web services can be composed into complex business processes.However,the BPEL does not support modifying Web services during the execution of business processes.Although the BPEL has fault handling and compensation mechanisms,the efficiency of business process execution will be affected if the business process could not be continued.In order to solve this problem,give a dynamic Web services composition framework based on the BPEL and QoS.By using the dynamic binding function of QoS components and the dynamic UDDI discovery of Web service,the business process run-time dynamic selection of Web service will be realized,and the efficiency in the execution of business processes will be improved as well.
