Web Services Technology Infrastructure

Web Services using eXtensible Markup Language (XML) based standards are becoming the new archetype for enabling business to business collaborations. This paper describes the conceptual architecture and semantics of constructing and consuming Web Services. It describes how Web Services fit into the enterprise application environment. It discusses Web Services security. Finally, it outlines the flaws of Web Services in their current state

Towards a service-oriented e-infrastructure for multidisciplinary environmental research

Research e-infrastructures are considered to have generic and thematic parts. The generic part provids high-speed networks, grid (large-scale distributed computing) and database systems (digital repositories and data transfer systems) applicable to all research commnities irrespective of discipline. Thematic parts are specific deployments of e-infrastructures to support diverse virtual research communities. The needs of a virtual community of multidisciplinary envronmental researchers are yet to be investigated. We envisage and argue for an e-infrastructure that will enable environmental researchers to develop environmental models and software entirely out of existing components through loose coupling of diverse digital resources based on the service-oriented achitecture. We discuss four specific aspects for consideration for a future e-infrastructure: 1) provision of digital resources (data, models & tools) as web services, 2) dealing with stateless and non-transactional nature of web services using workflow management systems, 3) enabling web servce discovery, composition and orchestration through semantic registries, and 4) creating synergy with existing grid infrastructures

The Conceptual Design and Implementing Web Services Security Framework for Ministry of Information and Communication Technology in Thailand

This research aims to present a Web Services Security Framework for Ministry of Information and Communication Technology (MICT) in Thailand as referred to international standard BS7799 on information security management. With a pilot development of web services which based on e-government, the researcher used Ministry of Information and Communication Technology as a case study. In order to understand the developmental pilot, it’s crucial to realize particularly in web services security and to determine proposed or existing system. Finally, it can be as standard guideline for Thai public organization for developing web services security framework

Tackling Interoperability in Composite Applications from an Enterprise Mash-up Perspective

The idea of a global mesh of enterprise composite applications is being impeded by the delay of next-generation interoperable mash-up platforms, providing intuitive human-guided resource interaction, reuse and composition. In this paper we revisit current mash-up platforms and analyze their major shortcomings with regard to the development of real composite applications. Then, we elaborate on a novel reference architecture for a mash-up platform called EzWeb/FAST. EzWeb/FAST facilitates the establishment of a user-centered mesh of interoperable resources that can be composed flexibly and easily to create and execute composite applications based on complex mashupable gadgets. The release of EzWeb/FAST will help enterprises to realize how SOA front-end innovations could make them more productive, responsive and, ultimately, more competitiv

Control Synchronous Web-Based Training Using Web Services

With the rapidly advancing technologies, training has been vital to keep companies competitive. Web-based training grows rapidly and attracts more attention for its most flexible manner. Virtual classroom is a form of synchronous web-based training. It provides real-time interactivity in learning process. I have developed a virtual classroom that uses Web services to control the audio/video transmission, chat box, whiteboard, and synchronous HTML presentation. Compared to an early implementation of the virtual classroom based on the Jini network, my Web-service based implementation has a significantly different control structure. My implementation has better interoperability
