Composing Web Services Based on Agent and Workflow
نویسندگان
چکیده
. Although web service has been regarded as a basic technology to support the next generation web, there are some deficiencies in this technology. A challenge to web service is how to compose several web services according to the business requirements. A web service composition framework WASC is proposed in the paper. In the WASC, different plans are defined as ECA rule set in the service agent and each plan can include several web service invoking activities. After receiving a request, service agent can determine to invoke which service so that the service independent plan will be turned into a service dependent plan by rewriting ECA rules. At the same time, workflow is used to coordinate the actions of service agents. The structures of WASC and service agent are discussed in the paper.
