This lecture describes a vision in which programs written in different languages, running on different platforms, and connected via different network transports can discover one another and communicate.

• The Vision
• SOA with publish-find-bind
• Infrastructure: SOAP, WSDL, and UDDI
• Platforms, including SAAJ and Apache Axis
• Consuming and Deploying services

• Read Chapter 9.
• Visir the xmethod site, look at some WSDL documents, and try a few services
• Examine the wsdl of the York Web Service at: http://indigo.cse.yorku.ca:4413/axis/YorkWS.jws?wsdl
• Examine the client YorkWSclient in the Resource Directory. Use a sniffer to look at the HTTP it sends and receives.
