Earlier this month, the W3C\'s XML Protocol Working Group released a Working Draft of SOAP 1.2. This specification is notable for several reasons. First, it\'s the first version of the protocol produced inside the W3C, rather than being a submission from member companies. Second, the name \"SOAP\" has been retained, rather than changed to \"W3C XML Protocol\", as one might expect. To some people this will be welcome news. Not everyone agrees with the W3C choosing generic names like \"XML Schema\" and \"XML Protocol\" for their technology standards, as if there could only ever be one.

Exception handling is an important aspect in any software application development. An exception is an event that occurs during the execution of a program that disrupts the normal flow of instructions. When the exception occurs in a Web Service, it will be propagated to the client as a SOAP fault. This article will help you understand different types of exceptions that could be thrown inside the Web Service and how user defined exceptions can improve error handling in your Web Service.

Due to the industry\'s intense promotional activities most IT professionals have been exposed to the concept of web services. They know that a web service is a distributed application that exposes its functionality using a set of XML standards, most likely including SOAP, UDDI, and WSDL. They\'ve heard repeatedly that this model offers the opportunity to better leverage existing investment in Internet technology by allowing companies to orchestrate business applications using components from various platforms throughout their enterprise. However, one fact is commonly overlooked. As with any emerging technology, the web services model presents its own set of implementation, process, and organizational challenges.

In my last column I sketched out an alternative to WSDL. In my ongoing attempts to suggest useful ideas for others to implement, I now want to spend some time discussing an implementation of a real service. I\'m going to look at XKMS, the XML Key Management Service. (A separate document specifies bindings to SOAP and HTTP.) This is a recommendation that has finished its W3C Last Call phase and is unlikely to see anything other than editorial changes at this point.

In a real-world scenario, Web services do not always use primitive data types. The real-world objects may be made of complex, user-defined data types. This article explains in detail the procedure for creating and exposing a Web service with user-defined data types deployed in a Weblogic SOAP container on a BEA Weblogic Server 8.x application server.

Q: I can\'t validate a document using namespaces, can I? I\'m trying to validate an XML file. It uses XML namespaces, but I can\'t figure out how to express them inside the DTD. Here\'s a sample XML document.

Amazon has recently introduced a new Simple Queue Service. Well, they haven\'t introduced it yet; it is still in Beta. So take this article with a grain of salt as the final service provided by Amazon may differ from what I describe here. The reason I am so interested in the Amazon service is that it\'s billed as having both SOAP and REST interfaces. Unfortunately, it\'s not living up to its billing. Let\'s learn how to use their service, and in addition, figure out how far they are from RESTful.

Web service standards have made outstanding progress. However, let\'s take a quick step backwards to examine an older standard called Universal Description, Discovery and Integration of Web services (UDDI). The UDDI specification defines a SOAP-based Web service for locating Web services and programmable resources on a network. It offers a foundation for sharing information about internal services across the enterprise and public services on the Internet.1

This article describes a new system for networking dictionaries and translation services on the Web. Think of this as GNUtella for language services. While the system described in this article may appear to be a huge undertaking, it will be built from many relatively simple components that talk to each other via a common client/server interface based on SOAP .

This week the World Wide Web Consortium announced the formation of a Web Services Activity. Within the W3C, \"Activity\" is the name given to an ongoing focus of development encompassing one or more Working Groups. Until this time, the W3C\'s only participation in the web services world was through the XML Protocol Working Group, which is essentially tidying up SOAP.
