SampleWebService Metadata

This topic contains the complete XML metadata for the Sample Web Service. As you know, it illustrates several complex Web service-related concepts in the Business Data Catalog. To better understand the sample, follow the walkthrough steps and review the comments in the SampleWebService metadata XML.

The source for the SampleWebService Web service is also included in the Microsoft Office SharePoint Server 2007 SDK download. Before importing the metadata, publish it on a Web server and update the WSDLFetchURL property accordingly.
