Core idea behind Real World Web Services is simple: after years of hype, what the major players really doing with web services? The core of this book is a series of projects, demonstrate the use and integration of Google, Amazon, eBay, PayPal, FedEx, and many more web services. Some vendors have been very successful with their web service deployment: for example, eBay processes over a billion web service requests a month! The author focuses on building 8 fully worked out example web applications that combine the best web services available today. This book really documents how to add functionality like automating listings for auctions, dynamically calculating shipping charges, automatically sending faxes to your suppliers, using an aggregator to pull data from various news and web service feeds into a single format or monitoring the latest weblog discussions and google search web site to keep visitors on topics of interest-by integrating APIs from popular websites most people are familiar with. For each application instance, the author provides a thorough overview, architecture, and full working code examples. This book does not engage in intellectual debate about the rightness of web services on a theological level.
