Abstract

This chapter presents our research initiative known as aspect-oriented framework for Web services (AoF4WS). This initiative looks into the role of aspect-oriented programming in enhancing Web services with nonfunctional properties that are orthogonal to the primary functional properties of Web services, without the need for extensive reprogramming. This enhancement achieves a separation between the functional and nonfunctional aspects of Web services, thereby resulting in easier adaptability and maintainability. We have initially chosen to focus on security and self-healing nonfunctional requirements. The AoF4WS initiative is therefore demonstrated using two projects, SC-WS and SHWS, which respectively stand for security concerns of Web services and self-healing Web services. Our contributions are relevant to the design phase in an aspect-oriented software development lifecycle.
