Popis: | Service-Oriented Architecture (SOA) is intended for the integration of heterogeneous applications. Complex business processes can be composed by a group of concrete Web services using WS-BPEL (Business Process Execution Language), and these Web services may be designed by the enterprise itself or provided by some third-party services providers. Today there are many WS-BPEL engines available that support the deployment and execution of WS-BPEL processes. However, WS-BPEL activities have to be pre-defined, and if at runtime a Web service invocation fails, the entire process is pronounced to be failed, thereby jeopardizing the reliability of SOA. Although WS-BPEL supports compensation and fault-handling mechanism, it is complex and not flexible. In this work, we propose a process design model to support dynamic Web services selection that eases the designer's job. This model has been implemented, and the prototype is evaluated to demonstrate that it indeed improves the overall business process reliability. |
