Patent number: 11205150Abstract: A model-driven and QoS-aware infrastructure facilitates the scalable composition of Web services in highly dynamic environments. An exception management framework supports two modes of exception management for business processes, providing a novel policy-driven approach to exception management implemented in the system infrastructure. Exception management is implemented in the system infrastructure, with exception handling policies supplied by individual business processes. Using the exception management framework, developers define exception policies in a declarative manner. Before a business process is executed, the service composition middleware integrates the exception policies with normal business logic to generate a complete process schema. This policy driven-approach can significantly reduce the development time of business processes through its separation of the development of the business logic and the exception handling policies.Type: GrantFiled: April 2, 2008Date of Patent: December 21, 2021Assignee: International Business Machines CorporationInventors: Jun-Jang Jeng, Hui Lei, Liangzhao Zeng, Hung-yang Chang, Santhosh Kumaran, Jen-Yao Chung
