Abstract: Service oriented architecture represents a model to build distributed applications by loosely integrating a number of web services. Due to the large variety of potential users and the dynamic loosely coupling nature, web services are subject to frequent evolution, which often requires to be done rapidly, and multiple versions may co-exist. In reality it is often the case that existing web services do not perfectly match user requirements in target systems. To achieve smooth integration and high reusability of web services, mechanisms to support automated evolution of web services in either functional or non-functional aspects are highly in demand. This paper advocates achieving the above evolution by applying a highly automated deep adaptation approach to the underlying components of web services. The approach works in an aspect-oriented component adaptation framework by generating and then applying the adaptation aspects under designed weaving process according to specific adaptation requirements. An expandable library of reusable adaptation aspects at multiple abstraction levels has been developed. A prototype tool is developed to scale up the approach
