The architecture of visual process modeling tools for Web services composition based on BPEL is introduced in detail. The concepts of arcs and nodes are imported and a visual process editor is implemented. Meanwhile, graphical method and the mapping technology which maps flow chart to BPEL elements are adopted. We give the method of describing QoS ontology of Web services and propose a solution to the service query and selection based on web service QoS constraint, which makes the web services that meet the consumers' requirement be bound with the business process dynamically and flexibly.
