The web services architecture provides a new way to think about and implement application-to-application integration and interoperability that makes the development platform irrelevant. Two applications, regardless of operating system, programming language, or any other technical implementation detail, communicate using XML messages over open Internet protocols such as HTTP or SMTP. The Simple Open Access Protocol (SOAP) is a specification that details how to encode that information and has become the messaging protocol of choice for Web services.Programming Web Services with SOAP is a detailed guide to using SOAP and other leading web services standards--WSDL (Web Service Description Language), and UDDI (Universal Description, Discovery, and Integration protocol). You''ll learn the concepts of the web services architecture and get practical advice on building and deploying web services in the enterprise.This authoritative book decodes the standards, explaining the concepts and implementation in a clear, concise style. You''ll also learn about the major toolkits for building and deploying web services. Examples in Java, Perl, C#, and Visual Basic illustrate the principles. Significant applications developed using Java and Perl on the Apache Tomcat web platform address real issues such as security, debugging, and interoperability.Covered topic areas include:

The Web Services ArchitectureSOAP envelopes, headers, and encodingsWSDL and UDDIWriting web services with Apache SOAP and JavaWriting web services with Perl''s SOAP::LitePeer-to-peer (P2P) web servicesEnterprise issues such as authentication, security, and identityUp-and-coming standards projects for web servicesProgramming Web Services with SOAP provides you with all the information on the standards, protocols, and toolkits you''ll need to integrate information services with SOAP. You''ll find a solid core of information that will help you develop individual Web services or discover new ways to integrate core business processes across an enterprise.

Given Perl''s natural fit for web applications development, it''s no surprise that Perl is also a natural choice for web services development. It''s the most popular web programming language, with strong implementations of both SOAP and XML-RPC, the leading ways to distribute applications using web services. But books on web services focus on writing these applications in Java or Visual Basic, leaving Perl programmers with few resources to get them started. Programming Web Services with Perl changes that, bringing Perl users all the information they need to create web services using their favorite language.Programming Web Services with Perl steers clear of the hype surrounding web services and concentrates on what is useful and practical. The book introduces the major web services standards, such as XML-RPC, SOAP, WSDL, and UDDI, and shows how to implement Perl servers and clients using these standards. You''ll find detailed references on both the XML and SOAP toolkits, and learn when to use one technology in favor of the other. The book is rich with programming examples that you''ll find useful well past the learning stage. And, moving beyond the basics, the book offers solutions to problems of security, authentication, and scalability.Some of the topics covered in the book are:

HTTP and XML basicsXML-RPC and the toolkitsSOAP and toolkitsSOAP::LiteUsing SOAP with SMTP and other protocolsAdvertising and discovering with UDDI and WSDLThe REST methodologyThe future of web servicesProgramming Web Services with Perl was written for Perl programmers who have no prior knowledge of web services. You can pick up this book without any understanding of XML-RPC or SOAP and be able to apply these technologies easily, through the use of publicly available Perl modules detailed in the book.If you''re interested in applying XML-RPC and SOAP technologies to distributed programming applications, then Programming Web Services with Perl is a book you''ll want to have.
