Service-Oriented Architectures SOA are widely used by companies to gain flexibility. Web services are the fitted technical solution used to support SOA by providing interoperability and loose coupling. Basic Web services are being assembled to composite Web services in order to directly support business processes. However, there is much to be done to obtain a genuine flawless Web service, and current market implementations do not provide adaptable Web service behavior depending on the service contract. This paper proposes two different approaches to increase adaptability of Web services and SOA. The first approach is based on Aspect Oriented Programming AOP as a new design solution for Web services. The authors have implemented an infrastructure to enrich services with aspects and to dynamically reroute messages according to changes, without redeployment. The second approach combines Model Driven Development MDD and Context-Awareness to promote reuse and adaptability of Web services behavior depending on the service context. Parameterized transformation techniques are proposed to bind context with business logic implemented by a service. The aim is to merge the two approaches to abstract and reduce the technical complexity of aspect based service solution.
