Obtaining WSDL URLs

Every Web service is described by a Web Services Description Language (WSDL). The WSDL defines the format of the SOAP messages used to send requests to and receive responses from the Web service, the transfer protocol used, namespace declarations, and other information. Several vendors, such as IBM, Microsoft, and SAP, have established Universal Description, Discovery, and Integration (UDDI) registries, to make Web services publicly available.

You can locate WSDLs on your own, or you can use Stylus Studio to search UDDI registries for published Web services.
