Composite Design Pattern for Feature Oriented Service Injection and Composition of Web Services for Distributed Computing Systems with Service Oriented Architecture

摘要

With the advent of newly introduced programming models like Feature-OrientedProgramming (FOP), we feel that it will be more flexible to include the newservice invocation function into the service providing server as a FeatureModule for the self-adaptive distributed systems. A composite design patternsshows a synergy that makes the composition more than just the sum of its partswhich leads to ready-made software architectures. In this paper we describe theamalgamation of Visitor and Case-Based Reasoning Design Patterns to thedevelopment of the Service Invocation and Web Services Composition through SOAwith the help of JWS technologies and FOP. As far as we know, there are nostudies on composition of design patterns for self adaptive distributedcomputing domain. We have provided with the sample code developed for theapplication and simple UML class diagram is used to describe the architecture.
