Lookup of Web Services: UDDI • Many possible ways to realize lookup with Web Services • UDDI is an automated directory service that allows one to register services and lookup services 138 • All UDDI specifications use XML to define data structures • An UDDI registry includes four types of documents: • A business entity is a UDDI record for a service provider. • A business service represents one or more deployed Web Services. • A technical model (tModel) can be associated with business entities or services. • A binding template binds the access point of a Web Service and its tModel. • UDDI allows a service provider to register information about itself and the services it provides Uwe Zdun, Markus Voelter, Michael Kircher - <strong>Remoting</strong> Patterns.
Other Web Service Frameworks Discussed • GLUE is a commercial Web Service implementation in Java that is optimized for ease-of-use and performance • Microsoft’s .NET Web Services: • .NET remoting • ASP.NET Web Services • IONA’s Artix • Tcl SOAP 139 Uwe Zdun, Markus Voelter, Michael Kircher - <strong>Remoting</strong> Patterns.
