4.1 Overview of Web servicesAs you may already be well aware, Web services have gained tremendousinterest and coverage in the IT industry in recent years. There have been manybooks published on the topic, so we do not attempt to cover the completespectrum of Web services in this chapter. We do, however, give a briefintroduction, so you may gain an understanding as to why you may want to useWeb services.4.1.1 What is a Web service?A widely accepted definition for a Web service is:“A self-contained, self-describing, modular application that can be published,located and invoked across the Web.”Web services enable the creation of applications that navigate, discover, and useother applications, in much the same way that people navigate, discover, anduse Web sites and Web-based business applications.With Web services, any business system can expose its underlying functionalityin new ways. A Web services layer allows developers to easily and dynamicallyincorporate that system’s functionality in any application, regardless of thelanguage it is written in or the platform it runs on. Once a Web service isdeployed, other applications (and other Web services) can discover and invokethe deployed service. The Web services model shifts the focus to integratingapplications, independent of platform, language, or data structure.4.1.2 Web service fundamentalsWeb services are built on the foundation of two technologies:► XML: The universal language for data description. XML’s separation ofcontent and presentation allows data to be manipulated in a reliable,automated way. Instructions or content represented by XML can beunderstood by any application that supports XML.► SOAP: The Simple Object Access Protocol uses XML messages to invokeremote methods. A Web service could interact with remote machines throughHTTP’s POST and GET methods, but SOAP is much more robust and flexible.In a typical Web services scenario, a business application sends a request to aservice at a given URL using the SOAP protocol over HTTP. The service receivesthe request, processes it, and returns a response.84 Lotus Instant Messaging/Web Conferencing (Sametime): Building Sametime-Enabled Applications
On the server side, a Web server and, for Java-based Web services, a servletengine is all that is required. On the client side, a programming language withXML and HTTP client support is all that is needed. It is possible to create a Webservice from an existing application without writing a single line of code, as 4.4,“Creating the UserStatus Web service” on page 97 illustrates.Web services are self-describing: neither the client nor the server needs to knowanything besides the format and content of the request and response messages.How the actual service works at the application level is irrelevant to the client,and how the client generates the request and what it does with the response isirrelevant to the server.You can generate an XML-based description of the Web service that explainshow it can be accessed. The Web Services Description Language (WSDL)allows Web services-enabled systems to tell each other what capabilities theyhave, and how to programmatically interact with them. Once a Web service isdescribed in WSDL, developers can create Web service clients to interact with it.You can also publish the Web service to a directory of Web services so that itcan be discovered by other Web service clients. Universal Description,Discovery, and Integration (UDDI) is an XML-based directory or registry of Webservices. UDDI provides a place for you to list your Web service and to find outabout others. The combination of WSDL and UDDI means Web servicedescription and discovery can be automated, allowing clients to bind todynamically-discovered services.With SOAP, you can send a request to another application, for example, to returnthe status of an item from a shipping system. You get the results back in a setformat that you can then process. To publish the shipping system as a Webservice, you register the application with an application server that supports theSOAP protocol (which runs as an HTTP extension). You can generate a WSDLdescription of the application that explains how it can be accessed. You can thenpublish that description to a UDDI directory.This section has been deliberately brief: we encourage you to gain a morein-depth understanding of Web services by consulting the Redbooks WebSphereVersion 5 Web Services Handbook, SG24-6891 and Web Services Wizardry withWebSphere Studio Application Developer, SG24-6292.4.2 Sametime Web servicesA Sametime Web service is simply a Web service layer that exposes thefunctionality of a Sametime application. Once you expose a Sametimeapplication as a Web service, you give any client capable of submitting an HTTPChapter 4. Web services 85
