Method, system, and web service broker for dynamic web service invocation

摘要

A method, system and Web service broker with requester's explicit control for dynamic Web service invocation. In accordance with the method a Web service request is constructed by a Web service requester, in which invocation criteria customized by the requester are included and the Web service request is sent to a Web service broker. The Web service broker discovers and invokes Web service implementation candidates that meet the invocation criteria based on the Web service request and returns the best invocation result as well as a session identifier for identifying this service request to the requester. The requester can explicitly control the process of Web service invocations through customized Web service requests, thus delegating the whole invocation process to a Web services broker to reduce the complexity of client-side tasks. In addition, the Web service invocation allows a series of invocations with a consistent business sense to be directed to the same Web service interface.
