Product Description
“Every developer working with the Web needs to read this book.” — David Heinemeier Hansson, creator of the Rails framework “RESTful Web Services finally provides a practical roadmap for constructing services that embrace the Web, instead of trying to route around it.” — Adam Trachtenberg, PHP author and EBay Web Services Evangelist You’ve built web sites that can be used by humans. But can you also build web sites that are usable by machines? That’s where the future lies, and that’s what RESTful Web Services shows you how to do. The World Wide Web is the most popular distributed application in history, and Web services and mashups have turned it into a powerful distributed computing platform. But today’s web service technologies have lost sight of the simplicity that made the Web successful. They don’t work like the Web, and they’re missing out on its advantages. This book puts the “Web” back into web services. It shows how you can connect to the programmable web with the technologies you already use every day. The key is REST, the architectural style that drives the Web. This book: Emphasizes the power of basic Web technologies — the HTTP application protocol, the URI naming standard, and the XML markup language Introduces the Resource-Oriented Architecture (ROA), a common-sense set of rules for designing RESTful web services Shows how a RESTful design is simpler, more versatile, and more scalable than a design based on Remote Procedure Calls (RPC) Includes real-world examples of RESTful web services, like Amazon’s Simple Storage Service and the Atom Publishing Protocol Discusses web service clients for popular programming languages Shows how to implement RESTful services in threepopular frameworks — Ruby on Rails, Restlet (for Java), and Django (for Python) Focuses on practical issues: how to design and implement RESTful web services and clients This is the first book that applies the REST design philosophy to real web services. It sets down the best practices you need to make your design a success, and the techniques you need to turn your design into working code. You can harness the power of the Web for programmable applications: you just have to work with the Web instead of against it. This book shows you how.

Product Description
“Other books claim to present the complete Web services platform architecture, but this is the first one I’ve seen that really does. The authors have been intimately involved in the creation of the architecture. Who better to write this book?” –Anne Thomas Manes, Vice President and Research Director, Burton Group “This is a very important book, providing a lot of technical detail and background that very few (if any) other books will be able to provide. The list of authors includes some of the top experts in the various specifications covered, and they have done an excellent job explaining the background motivation for and pertinent details of each specification. The benefit of their perspectives and collective expertise alone make the book worth reading.” –Eric Newcomer, CTO, IONA Technologies “Most Web services books barely cover the basics, but this book informs practitioners of the “real-world” Web services aspects that they need to know to build real applications. The authors are well-known technical leaders in the Web services community and they helped write the Web services specifications covered in this book.Anyone who wants to do serious Web services development should read this book. ” –Steve Vinoski, Chief Engineer, Product Innovation, IONA Technologies “There aren’t many books that are as ambitious as this one is.

Michael Guttman, Object Management Group authority on Model Driven Architecture (MDA) and coauthor, Real-Life MDA
“Gives programmers and managers a friendly and rapid introduction to service-oriented architecture, with practical examples.” —Frank Cohen, author, FastSOA
“Margolis and Sharpe (both, IBM) provide a very comprehensive introduction to Service Oriented Architecture (SOA) for programmers. Highly recommended.” —Choice
Product Description
Service-Oriented Architecture (SOA) is a way of organizing software. If your company’s development projects adhere to the principles of SOA, the outcome will be an inventory of modular units called “services,” which allow for a quick response to change.
This book tells the SOA story in a simple, straightforward manner that will help you understand not only the buzzwords and benefits, but also the technologies that underlie SOA: XML, WSDL, SOAP, XPath, BPEL, SCA, and SDO. And through it all, the authors provide business examples and illustrations, giving a practical meaning to abstract ideas.
SOA for the Business Developer
• Gives a detailed overview of Extensible Markup Language (XML), including namespaces and XML schema.
• Describes Web Services Definition Language (WSDL) and SOAP, the standard SOA technologies.
• Gives a clear tutorial on XML Path Language (XPath), a language for deriving data from transmitted messages and other sources. XPath is useful for working with a variety of other technologies, including several described in this book.
• Gives comprehensive details on BPEL 2.0, a language that coordinates services and whose preceding version is already in numerous products. Our coverage is sufficient for most of your work with BPEL and includes a quick-reference guide.
• Introduces Service Component Architecture (SCA), a proposed standard for composing and deploying applications. You’re sure to hear more of SCA, which is sponsored by 18 companies, including IBM, Oracle, and Sun Microsystems.
• Introduces Service Data Objects (SDO), a proposed standard for representing data in a single way, even if the data comes from different types of data sources. SDO is likely to accompany SCA into the limelight
Security for Web Services and Service-Oriented Architectures
July 17, 2009 by BPELworld.com · Leave a Comment
Web services based on the eXtensible Markup Language (XML), the Simple Object Access Protocol (SOAP), and related standards, and deployed in Service-Oriented Architectures (SOA), are the key to Web-based interoperability for applications within and across organizations. It is crucial that the security of services and their interactions with users is ensured if Web services technology is to live up to its promise. However, the very features that makes it attractive – such as greater and ubiquitous access to data and other resources, dynamic application configuration and reconfiguration through workflows, and relative autonomy – conflict with conventional security models and mechanisms. Elisa Bertino and her coauthors provide a comprehensive guide to security for Web services and SOA.They cover in detail all recent standards that address Web service security, including XML Encryption, XML Signature, WS-Security, and WS-SecureConversation, as well as recent research on access control for simple and conversation-based Web services, advanced digital identity management techniques, and access control for Web-based workflows. They explain how these implement means for identification, authentication, and authorization with respect to security aspects such as integrity, confidentiality, and availability. This book will serve practitioners as a comprehensive critical reference on Web service standards, with illustrative examples and analyses of critical issues; researchers will use it as a state-of-the-art overview of ongoing research and innovative new directions; and graduate students will use it as a textbook on advanced topics in computer and system security.
