Web Service Question

[Newsgroup_User]

I am hoping there is a simple fix for this. I created a web service that I
can get to work fine with a cfinvoke:
<cfinvoke
webservice =
" http://realitorToolBox/model/webservices/PropertySearch.cfc?wsdl"
method = "getCities"
refreshwsdl="true"
returnVariable = "listCities">

But when I switch to a function and use createObject:
<cffunction name="allCities" access="public" returntype="query" output="no"
hint="I display all Cities for the home page search engine">
<cfset CityGateway = createObject("webservice",
" http://realitorToolBox/model/webservices/PropertySearch.cfc?wsdl")>
<cfset allCities = CityGateway.getCities()>
<cfreturn allCities>
</cffunction>

I get this error:
Web service operation getCities with parameters {} cannot be found.

Any ideas why?

Here is the web function
<cffunction name="getCities" access="remote" returntype="query"
output="false" hint="I return all the cities in the database to search">
<cfquery name="listCities" datasource="datasource">
Select DISTINCT(City) FROM residential
ORDER BY City ASC
</cfquery>
<cfreturn listCities>
</cffunction>

Nevermind. I added the createObject to the controller and it worked fine
instead of pointing it to another function.
