  With the advent of newly introduced programming models like Feature-Oriented
Programming (FOP), we feel that it will be more flexible to include the new
service invocation function into the service providing server as a Feature
Module for the self-adaptive distributed systems. A composite design patterns
shows a synergy that makes the composition more than just the sum of its parts
which leads to ready-made software architectures. In this paper we describe the
amalgamation of Visitor and Case-Based Reasoning Design Patterns to the
development of the Service Invocation and Web Services Composition through SOA
with the help of JWS technologies and FOP. As far as we know, there are no
studies on composition of design patterns for self adaptive distributed
computing domain. We have provided with the sample code developed for the
application and simple UML class diagram is used to describe the architecture.
