This discusses the overall roadmap of topics for the course. Describes what web services are and what they are for. Provides a brief introduction to SOAP and WSDL. It also introduces the concept of the projects and their basic structure.

Resources

Detailed discussion of the SOAP and WSDL specifications. Includes several examples of each. Also demonstrates the Google and Amazon web services APIs and describes their WSDL definitions

Resources

This lecture describes at a high level that various styles of web services: RPC, document, wrapped and message-oriented. We then concentrate on showing how to both build and use simple RPC style web services. We demonstrate this using Visual Studio (consuming an existing web service from xmethods.net and creating a new web service), Systinet WASP and Apache Axis. The demonstrations are not fully contained in the slides.

This lecture describes how to build more advanced, coarse-grained, asynchronous web services with direct control of the XML payloads. Specifically this class:

• - will show how to build and consume asynchronous web service with .NET and Java web service products
• - describes how to build message style web services with Java tools (Axis and Systinet) and .NET
• - present API alternatives for creating and consuming XML documents for web services payload
• - describe some general design guidelines for more scalable, performant web services

This class first describes the requirements for a web service registry, and why a location to publish (possibly internally only) the availability of a web service is crucial to realizing the promise of web services. We then detail how UDDI was originally built to address these requirements. We present the current design of the UDDI V3 specification in detail. We describe various technical notes that are additive to the UDDI specification to make it work well with other web service standards. Future plans for UDDI are summarized.
