An aspect oriented approach for context-aware service domain adapted to e-business

Abstract

This paper proposes an architecture for a high-level structure called Service Domain which orchestrates a set a of related IT services based on BPEL specification. Service Domain was developed to enhance the Web service concept to suit e-business collaboration. Service Domains are developed to be context aware. Our approach highlights the benefits of bringing Aspect Oriented Programming to ensure context aware services. Thus, context awareness is guaranteed by enhancing BPEL execution using Aspect oriented paradigms. The proposed approach is illustrated with a running example that shows how Service Domain presents different behaviours according to the context changes. © 2008 Springer-Verlag Berlin Heidelberg.
