Hi Chris,
I have been following this thread out of curiosity, and I think I
might be able to help in pointing you in the right direction.
The key bit here is the fact that the getIPAddress method has an input
parameter, identified in the dump of the stub as:
localhost.webservices.UsedCarWS.IPAddress
In the WSDL, this is defined as:
<s:element name="IPAddress">
<s:complexType/>
</s:element>
So it's a complex type, but has no child elements, which corresponds
to an empty CF structure. Therefore, if you change your code snippet
to:
<cfscript>
wsurl = "https://www.blackbookws.com/UsedCarWS.asmx?WSDL";;
portname = "UsedCarWSSoap12";
ws = CreateObject("webservice", wsurl, portname);
ip = StructNew();
</cfscript>
<cfdump var = "#ws#">
<cfdump var = "#ws.getIPAddress(ip)#">
The second dump will display the object returned by the method call,
which in turn has a getIPAddressResult() method that returns the IP of
the CF server calling the web service:
<cfscript>
wsurl = "https://www.blackbookws.com/UsedCarWS.asmx?WSDL";;
portname = "UsedCarWSSoap12";
ws = CreateObject("webservice", wsurl, portname);
ip = StructNew();
response = ws.getIPAddress(ip);
</cfscript>
<cfdump var = "#response.getIPAddressResult()#">
Hope that helps.
