Invoking the Web service method

SoapConnection is used to create the Soap_proxy object with connection options that you set using SoapConnection object methods. Once a proxy object for a Web service is created, the client application can begin accessing the Web service. To invoke a Web service method, the proxy object must contain the following information:

  • End point of service, obtained from a WSDL file

  • Namespace definition used in the SOAP method call

  • Any structure definition, when applicable

  • An instance variable for each returned structure array, since all returned arrays are any 

  • One or more SOAP methods and corresponding alias strings
