Abstract
Contract monitoring is a complex activity which requires code instrumentation and many additional functions to be implemented both in the client and server sides. This paper proposes an approach to simplify QoS monitoring based on the aspect-orientated paradigm. The objective of this paradigm is to increase modularity by allowing the separated expression of cross-cutting concerns and the automatic reunification of them into a whole system. We consider that an e-contract consists of collaborative partners, a business process specified in AO4BPEL and QoS attributes defined with WS-Agreement. Monitoring concerns are encapsulated into aspects to be executed when specific process points are reached. Differently from other approaches, the proposed solution requires no instrumentation, uses Web services standards, and provides an integrated infrastructure for dealing with contract establishment and monitoring. Moreover, a Business Process Management Execution Environment is designed to automatically support the interaction between customer, provider and monitor organizations.
