SMS – A Share Memory Service for Web Service Oriented Applications

Abstract

Software as services, or web service oriented application can be treated as the next evolution technology for implementing dynamic e-Business solutions. The major advantage of using web services is that they can be considered as loosely coupled dynamically bound components with great interoperability. However, it becomes complicated to implement a web service when its states or data are required either to be passed or to be shared by the other services. In this paper a new service called Share Memory Service (SMS) is proposed. It provides a mechanism for the services in a web service oriented application to pass session context and share their data or objects transparently. Web service oriented applications built upon SMS are called SMS applications. A set of API for developing SMS applications is also provided. In this research, we use Java technology to verify our proposed solution. Furthermore, in order to simplify the coding effort, five new Java pseudo- instructions are introduced. With these new instructions, developers need not use the API directly when developing an SMS application. Also the concept of the capability of using global data and objects in a web service oriented application can simplify the system design process.
