OpenEdge 10 supports the ability to easily invoke a Web service. Join Principal SW Engineer, Michael Resnick, as he presents the basic concepts of a web service.
Learn about the tools and the Progress 4GL constructs that you will use to invoke a Web service method. Find out the basic steps required to call a Web service from the Progress 4GL. Learn how the WSDL Analyzer makes it simple to invoke a Web services application and how the 4GL hides the complexity of dealing with SOAP messages. In addition, you'll learn how complex data is handled in the 4GL.

NOTE: As of March 2009, Google no longer supports the SOAP interface used in the example shown in this presentation.
Again, neither of these examples are current. Neither Google nor PSC have these services running.
I agree. It is very frustrating to try to learn about this stuff when the sample services no longer exist.
