Dynamic Web Service Deployment Using WSPeer

This paper describes how WSPeer, a framework for deploying and invoking Web services, allows application code to host and invoke Web services. We show how the mechanisms used by WSPeer shield applications from implementation changes and enable applications to easily expose elements of themselves as Web services. The mechanisms described differ from usual Web service deployment scenarios in which a service is deployed into a container framework which manages the service environment. Instead WSPeer leaves control in the hands of the application. This allows Web services to be created and deployed that can respond dynamically to application requirements.
