XML Based Robust Aspect Composition in Web Service

Web service technology has been successful in making business applications available through the internet to a large number of users. But because some non-functional attributes such as logging, security, transaction, etc. are scattered in web services, adaptation, composition and reusability of web service are affected. Aspect-Oriented Programming (AOP) helps us solve this problem of web services. Although AOP provides a good way to modularize concerns not designed to collaborate, conflicts may occur when multiple aspects are combined. When multiple aspects are applied to an application at a time, unexpected results can be produced because of aspect interference. Therefore, in this paper we propose a robust aspect composition in web service using XML (Extensible Markup Language). This paper focuses on the representation and composition of aspects at the shared join points.
