Develop apps with Web services and the eBay SDK, Part 1: Build an eBay search engine

Alex Garrett (ljagged@thinkpig.org), Senior Consultant, Isthmus Group, Inc.
After pursuing an undergraduate degree in classics, linguistics, computer science, psychology, and literature, Alex finally settled on a B.S. in philosophy from the University of Wisconsin. His professional career is as checkered as his academic one. He has been the e-commerce architect for a GE Capital company, a lecturer at a University of Wisconsin school, a systems administrator, an acquisitions editor for a small technical publishing company, and a code toad, among other things. Currently, he's a senior consultant with a Madison, WI-based firm and a proud new father.

Summary:  The face of eBay® that most people are familiar with is the company's Web presence. Learn how to write a small application that allows users to execute ad hoc queries against eBay through eBay's SOAP API. The application uses the eBay Java™ SDK. The use case is targeted at a small subset of the API, but you can generally apply the principles.

Wrap-up

Conclusion

This tutorial demonstrated that the eBay SDK is fairly straightforward to use. It's mostly a matter of finding the correct call class, setting its attributes with the appropriate parameters, and invoking it. You don't need to mess with the SOAP pieces. However, it's a bit ingenuous to imply that building eBay applications with the SDK is easy. If it were, the SDK wouldn't ship with a 958-page PDF document; and the developer site wouldn't have forums, and FAQs, and a knowledgebase, and whitepapers, and sample code, and application development classes in streaming video. The eBay SDK is a bit like XML -- it's easy to learn, but it's hard to understand and use well. The good news is that eBay has made available all the resources just mentioned to help make your life as an eBay application developer easier. As I mentioned earlier, the company has a vested interest in getting developers to write applications that use its Web service API, and it will make the process as easy as possible for you. Take advantage of the situation and jump in with both feet.
