An Aspect Oriented Approach for Applying Features to Web Services

Abstract

Web services are required to handle non-functional concerns. Such concerns can be divided to common features (security, reliability, manageability, etc.) and business specific requirements. Many of the common features are handled by toolkits such as Microsoft Web Services Enhancements, IBM Emerging Technologies Toolkit and Apache Axis.The two main problems this paper aims to solve is the inability of current toolkits to apply a feature to multiple Web Services in a single process and the fact that current toolkits require developer's knowledge to apply features to Web Services. As a solution, this paper proposes an Aspect Oriented approach for applying features to Web Services.The aspect oriented approach presented by this paper should make the process of applying features to Web Services less resource consuming and more flexible than the approach taken by current toolkits.

Using Aspects for Platform-Independent to Platform-Dependent Model Transformations

“…The approach was motivated by weaknesses of the current composite specification, such as BPEL. In (Abu-Eid, 2007) it is presented an aspect oriented approach which aims to make the process of applying features to web services more flexible and less resource consuming. The approach introduced an aspect oriented extension module which modularizes the logic of applied features.…”

Automatic Derivation of Performance Models in the Context of Model-Driven SOA

“…In [ABU07], another aspect oriented approach aims to improve process flexibility when applying features to web services and to reduce resource consumption. To achieve the goals, the proposed approach defines an aspect oriented extension module, called aspect binding, which modularizes the logic of applied feature.…”
