Web Services Description Language (WSDL) is an XML format defined by the World Wide Web Consortium (W3C). Each WSDL file describes network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information.
A WSDL file describes a SOAP service. It includes XML schema information that describes the input parameter values that need to be sent in a SOAP request message, and the output parameter values that can be extracted from a SOAP response message.
It also specifies the delivery method (usually HTTP) and the URL of the PRPC servlet that processes the SOAP requests. Software tools are available that generate WSDL files from other representations of the service.
Use the Connector and Metadata accelerator to define a connector, classes, and properties from a WSDL file.
