About this tutorial

Purpose of this tutorial

Learn how to create a Web service that provides a DVD rental service and a client for that service. The next two tutorials will cover some additional services as outlined below:

• Two DVD rental services
• A rental service search aggregator service

The two DVD rental services have slightly different interfaces to show you how the search aggregator can search two (slightly) disparate sources. Initially we only focus on the client side of the Web service, which will access the aggregator that searches for and sends rental recommendations. The next 2 tutorials will cover the aggregator and DVD Rental provider's interfaces more in depth.

About the labs in this series

All of these tutorials focus on a DVD rental search engine that aggregates search results from one or more DVD rental shops that have made their catalogs available online. The use case we address, Rental Recommendation , involves allowing users to submit the movie category they would like to rent and, based on their rental history, using Web services to suggest other movies. In the first tutorial ("Build SOA with Web services using WebSphere Studio, Part 1: Introduction to SOA and Web services," see Resources), we simply created a simple Web service and ran it. In this secod tutorial, you can expand your exploration of working with Web services with three labs:

• Lab 1: Build and deploy a Web service -- In this lab you create and deploy a simple Web service that your aggregator will expose for the client.
• Lab 2: Exchange complex SOAP objects -- In this lab you can enhance your Web service by allowing it to return more complex SOAP objects for your rental client to use.
• Lab 3: Dynamic Web service client -- In this lab you can dynamically create a Web service client for consuming the complex SOAP objects.
