The Design of Stateful Web Services Based on Web Service Resource Framework Implemented in Globus Toolkit 4

Abstract

Web services are the technology of choice for Internet-based applications with loosely coupled clients and servers. The state is kept in an entity called resource. Web service resource framework is an open framework for modeling and accessing stateful resources using Web services. The paper approaches the main issues that should be taken into consideration during the design process of stateful Web services: using the factory design pattern for creating resources, registering resources in an index service, building a secure Web service, accessing resource properties through the methods exposed in interfaces, lifetime management and notifications
