Ironically, that bit of code that were talking about regarding instantiating the object was borrowed from the CF documentation regarding handling complex types in CF web services.
Actually there is no documentation that indicates that you can pass a CFC as a web service argument but you can return it as a web service response. The WSDL is formed correctly to accept it as an argument so that's why I was led to believe that you could pass in the object as an argument. How CF handles structures and arrays of structures for web services is not very standard, in terms of interoperability. Yes, it can be done, but if another system or platform were to access the service, it would require some additional hand-holding on that system to create a request that CF would accept and be able to manipulate, which may not be possible in some cases. My goal is to come up with a WSDL that defines the structure of the request so that the arguments are self-explanatory and are not embedded inside of an XML argument. Thanks for your help and suggestions, Mike! -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ferris, Mike Sent: Monday, March 19, 2007 3:53 PM To: Dallas/Fort Worth ColdFusion User Group Mailing List Subject: RE: [DFW CFUG] Problem Invoking CF webservice with an arrayofcomplextype Rick, As a matter of best practice, if using a .cfc to create an object, I would specifically instantiate the object with an init() method. Again, as best practice, although ColdFusion dynamically type casts, the WSDL specifies double, so I would use a numeric rather than string representation of the value. A colleague suggested that the problem may be that you cannot pass a CF object when invoking a webservice. Could you create objOrderLine as a structure and send an array of structures instead? Or, maybe as an XML document?

I don't know if the instantiation is required. I've used this code before but not in cfscript syntax. I might try it as CFML instead of using cfscript. Regarding the double data type, ColdFusion actually converts the CF type of "numeric" to a double. When I invoke the submitOrder service in my CF page, CF automatically converts my argument value to the appropriate data type as defined in the WSDL. If there's something I've stated above that isn't right, please let me know.

You create the "objOrderLine" component, but don't invoke or instantiate an init() or any other method. You start assigning values to it as if it is a structure. Also, you define the Price to be double, but send a string - "19.99". Hope this helps.

I *think* I'm passing in the correct parameters and it appears that the WSDL is being generated properly, but for some reason it's not liking the complex type argument that I'm passing in. Here is an example of the WSDL: <element name="submitOrder"> <complexType> <sequence> <element name="customerNumber" type="xsd:string"/> <element maxOccurs="unbounded" name="orderLine" type="impl:OrderLineInput"/> </sequence> </complexType> </element> <complexType name="OrderLineInput"> <sequence> <element name="Quantity" nillable="true" type="xsd:double"/> <element name="Product" nillable="true" type="xsd:string"/> <element name="Price" nillable="true" type="xsd:double"/> <element name="Discount" nillable="true" type="xsd:string"/> </sequence> </complexType> This is my code to invoke the web service and pass in the arguments: <CFSET arrOrderLine = ArrayNew(1)> <CFOBJECT component="OrderLineInput" name="objOrderLine"> <cfscript> objOrderLine.Quantity = 1; objOrderLine.Product = "XYZ"; objOrderLine.Price = "19.99"; objOrderLine.Discount = "0"; ArrayAppend(arrOrderLine, objOrderLine); ws = CreateObject("webservice", "http://localhost/components/Order.cfc?wsdl";); result = ws.submitOrder(customerNumber="ABC123", orderLine=arrOrderLine); </cfscript> I'm getting this error: Web service operation "submitOrder" with parameters [EMAIL PROTECTED], ....could not be found. This usually indicates that I missed a parameter or it didn't like the parameters I passed in. If anybody can help me clue in on what I'm doing wrong, I'd greatly appreciate it.
