Question

I’m building a WebService in ColdFusion 8 using CFCs with remote methods. I need to specify complex data types in the WSDL, so I’m creating CFCs for each of these types. For instance, let’s say I have a “Person” type. It includes an “age” property. This property needs to always be an integer. However, ColdFusion does not have “integer” as a valid type – only Numeric, which translates to “xsd:double” in the WSDL. How can specify that a property – or an argument, for that matter – has a type of “integer”?

FYI, Henry’s answer is very helpful, but I’m trying to return an Object from the function – not just an integer. I need one of the properties to be returned as an integer.

1. Write your own WSDL. Save your CFC and capture the RPC generated WSDL by pointing your browser at http://mysite/mypath/myCFC.cfc?WSDL
   Grab the source, or clean up all the – added by your browser. Make
   sure there is no white space before the <?xml version tag.
   Find the xsd:double in the Response message and change it to xsd:int.

2. Specify the WSDL in your component. Add the wsdlfile="mywsdl.wsdl" attribute with the filename and add the attribute style="document"
   which is required for user-defined WSDLs.

3. Bind the webservice to the WSDL ColdFusion does this automatically — but it caches them. When a WSDL changes, you need to restart the service or go to “Data & Services -> Web Services” in CF
   Administration and refresh the service.

4. Change your cffunction to return "Any" instead of "Numeric"

5. In your cfreturn, instantiate a Java Integer <cfreturn createObject("java","java.lang.Integer").init(JavaCast("int",myvalue))
   />
