Creating a Client from WSDL

To create a web service client that can access and consume a web service provider, you must obtain the information that defines the interoperability requirements of the web service provider. Providers make this information available by means of WSDL files. WSDL files may be made available in service registries or published on the Internet via a URL (or both). You can use a web browser or the Netbeans IDE to obtain WSDL files.

A WSDL file contains descriptions of the following:

Web Services Metadata Exchange (WS-MEX) is the protocol for requesting and transferring the WSDL from the provider to the client. This protocol is a bootstrap mechanism for communication. When the type of metadata desired is clearly known (for example, WS-Policy), a client request may indicate that only that type should be returned.
