Summary: The current emphasis on Service-Oriented Architectures (SOA) has put the spotlight on web services, but it's easy to get lost in all the information being bandied about. This series gives you the straight story on all of the major web service specifications, starting with Simple Object Access Protocol (SOAP) and working down to WS Business Process Execution Language (WS-BPEL). In this second installment, you'll learn about Web Services Definition Language, as the Daily Moon Classified Department uses WSDL to describe their own web service in such a way that others can easily create clients to access it from any programming language or platform.

Summary

In Part 1 of this series, the Classifieds Department of the Daily Moon newspaper learned how to use SOAP web services to connect with the newspaper's Content Management System. In this tutorial, the staff learned to use Web Services Description Language (WSDL) to describe their own services so that others could use them. The tutorial covered the basics of XML schema, along with the structure of a WSDL file so that it can be built by hand. It also discussed the differences between the various styles and encodings available. The tutorial also explained how to use the Java2WSDL and WSDL2Java tools that come with Apache Axis2 to automatically generate WSDL from Java files, and vice versa.

Part 3 of this series will look at building web service registries using UDDI.
