Note

This topic pertains to a legacy technology. XML Web services and XML Web service clients should now be created using Windows Communication Foundation.

Web services are components on a Web server that a client application can call by making HTTP requests across the Web. ASP.NET enables you to create custom Web services or to use built-in application services, and to call these services from any client application. We suggest the following progression of documentation to help you navigate through the related topics.

This web service is using http://http://www.zjjv.com/// as its default namespace.

Recommendation: Change the default namespace before the XML Web service is made public.

Each XML Web service needs a unique namespace in order for client applications to distinguish it from other services on the Web. http://http://www.zjjv.com/// is available for XML Web services that are under development, but published XML Web services should use a more permanent namespace.

Your XML Web service should be identified by a namespace that you control. For example, you can use your company's Internet domain name as part of the namespace. Although many XML Web service namespaces look like URLs, they need not point to actual resources on the Web. (XML Web service namespaces are URIs.)

For XML Web services creating using ASP.NET, the default namespace can be changed using the WebService attribute's Namespace property. The WebService attribute is an attribute applied to the class that contains the XML Web service methods. Below is a code example that sets the namespace to "http://http://www.zjjv.com///webservices/":

C#[WebService(Namespace="http://http://www.zjjv.com///webservices/")]

public class MyWebService {

// implementation

}

Visual Basic<WebService(Namespace:="http://http://www.zjjv.com///webservices/")> Public Class MyWebService

' implementation

End Class

C++[WebService(Namespace="http://http://www.zjjv.com///webservices/")]

public ref class MyWebService {

// implementation

};

For more details on XML namespaces, see the W3C recommendation on Namespaces in XML.

For more details on URIs, see RFC 2396.
