The Research Of Global XML Web Services Protocols

XML (Extensible Markup Language) Web services have become the fundamental building blocks for integrating applications as organizations have begun to use distributed computing on the Internet. Web services are successful for two reasons: They are based on open standards that make them interoperable, and the technology that is used to implement them is ubiquitous.The Simple Object Access Protocol (SOAP), the Web Services Description Language (WSDL), and the Universal Description, Discovery, and Integration (UDDI) specifications constitute a set of baseline specifications that provide the foundation for integrating and aggregating applications. But, as organizations develop Web services, their solutions have become more complex and their need for standards beyond this baseline has increased. Higher-level functionality such as security, routing, reliable messaging, and transactions in proprietary and often non-interoperable ways becomes increasingly important.Accord to the requirement, this article provides analysis and research of Global XML Web Services protocols, (GXA Web Services: WS-Security, WS-Routing, WS-Referral), and the content is as below: Analyze limitations inherent to the specifications with which today's Web services are built. Analyze the design principles and specifications of (GXA). Analyze Web service application scenarios that Web Services Routing Protocol (WS-Routing) and Web Services Referral Protocol (WS-Referral) make possible. Explain how to use Web Services Security Language (WS-Security) to perform authentication and authorization for Web services. Design Web services that anticipate and can leverage the features that GXA will offer when released.
