Course Description
Web services enable computer programs to communicate with each other across application, operating system, hardware and organizational boundaries via XML documents and open standard Internet protocols. This course covers the basic standards that enable web services: SOAP, WSDL, and UDDI. It describes proper design of web services and applications to use them within a service-oriented architecture. Programming techniques for consumption and implementation of web services are demonstrated. The roadmap and motivation of future web services standards is laid out. Over the course of the semester students will build a significant web service project and incrementally enhance it as new techniques and web service standards are learned. The course will be graded on the basis of this project as well as midterm and final exams.

Topic Review and Mobile Web Services
I distributed Sprint 6700 Windows Mobile 5 devices to all project teams before class. Then I lectured on remaining material in UDDI lecture and about asynchronous web services. Finally I showed building a sample mobile app to consume web services from a Windows Mobile 5 device.

This class shows how to create web services with: - confidentiality - encryption via WS-Security and XML Encryption - integrity - signing via WS-Security and XML Signature - compliance with security policies - negotiated via WS-Policy and WS-SecurityPolicy We also describe methods of securing your web service assuming that you do not have the ability to use a WS-Security supporting SOAP implementation.
