As a developer new to Web Services, how do you make sense of this emerging framework so you can start writing your own services today? This concise book gives programmers both a concrete introduction and a handy reference to XML web services, first by explaining the foundations of this new breed of distributed services, and then by demonstrating quick ways to create services with open-source Java tools.Web Services make it possible for diverse applications to discover each other and exchange data seamlessly via the Internet. For instance, programs written in Java and running on Solaris can find and call code written in C# that run on Windows XP, or programs written in Perl that run on Linux, without any concern about the details of how that service is implemented. A common set of Web Services is at the core of Microsoft's new .NET strategy, Sun Microsystems's Sun One Platform, and the W3C's XML Protocol Activity Group.In this book, author Ethan Cerami explores four key emerging technologies:
XML Remote Procedure Calls (XML-RPC)
SOAP - The foundation for most commercial Web Services development
Universal Discovery, Description and Integration (UDDI)
Web Services Description Language (WSDL)
For each of these topics, Web Services Essentials provides a quick overview, Java tutorials with sample code, samples of the XML documents underlying the service, and explanations of freely-available Java APIs. Cerami also includes a guide to the current state of Web Services, pointers to open-source tools and a comprehensive glossary of terms.If you want to break through the Web Services hype and find useful information on these evolving technologies, look no further than Web Services Essentials.

Ethan Cerami is a Senior Software Engineer at the Center for Computational Biology at Memorial Sloan Kettering Cancer Center, and an adjunct faculty in the Department of Computer Science at New York University. He is the author of Web Services Essentials (O'Reilly), and is currently hard at work on "XML for Bioinformatics" (O'Reilly).
Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Web Services Essentials is a spiny lobster (also known as a rock lobster). There are about 45 species of spiny lobster worldwide, ranging in size from 2 to 26 pounds. Spiny lobsters have spine-studded shells and long antennae. However, unlike American lobsters, they have no large front claws. Spiny lobsters also have larger tails than American lobsters. They are colorfully marked with bright green, blue, and yellow spots on an orange or brown shell. Spiny lobsters inhabit shallow-watered, rocky environments in tropical and subtropical waters worldwide, as well as in cold waters of the southern hemisphere. Spiny lobsters usually remain concealed in rock crevices during the day and come out to feed at night. They eat a wide variety of foods, including shellfish, crabs, small fish, sea urchins, and sometimes algae and seaweed. They reach sexual maturity at 7 to 10 years and can live for over 30 years.Although they are reclusive, spiny lobsters seem to be more social than American lobsters and often share their dens in coral reefs. One of the stranger sights reported by fishermen and divers is the so-called "March of the Spinys," which is a mass migration of hundreds or even thousands of spiny lobsters that often takes place in October or November, usually after a period of prolonged storminess. During this time, spiny lobsters swim in single-file columns, moving from shallow to deeper waters. Although the lobsters are nocturnal creatures, these marches sometimes occur in broad daylight. To date, there is no scientific explanation for this phenomenon. Claire Cloutier was the production editor and copyeditor for Web Services Essentials. Rachel Wheeler was the proofreader. Sarah Sherman and Jeffrey Holcomb provided quality control. Phil Dangler, Edie Shapiro, Sarah Sherman, and Derek Di Matteo provided composition assistance. Nancy Crumpton wrote the index.Ellie Volckhausen designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1, using Adobe's ITC Garamond font.David Futato designed the interior layout. Mihaela Maier and Neil Walls converted the files from Microsoft Word to FrameMaker 5.5.6, using tools created by Mike Sierra. The text font is Linotype Birka; the heading font is Adobe Myriad Condensed; and the code font is LucasFont's TheSans Mono Condensed. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. The tip and warning icons were drawn by Christopher Bing.

This is a very good book for the novice of web service.
Except that I found an error in the example of XML-RPC, the Area example at page 40, the AreaServer.startServer method lacks an start(). it should be corrected to adding server.start() to start the webserver.
Otherwise, the book has a very clear description of web services, and I spent only 4 days from knowing-nothing to a webservice developer with this book.
I am new to the web services and decade old to programming. This book starts with the introduction to web services and continues with xml-rpc and an example java. Next chapter is SOAP and has instruction to install and configure Apache SOAP and continues with WSDL and UDDI. Each chapter has enough examples in java to understand how to write each of the above components. I would say this is best book to introduce to web services.
I was dissapointed by this book because it lacked any clear insight or coverage of the conceptual features of Web Services technology. I got the impression the author had little experience of other distributed RPC protocols/frameworks before coming to web services.
* Coverage of the difficult issue of marshalling objects between different languages and type systems was scare and scattered.
* Contained too many blocks of bland XML data and screenshots of Internet Explorer that added little value.
* Did not mention any problems/issues with Web Services technology, and came across a little evangelical.
