consuming coldfusion webservices - web-services

Question

I am trying to build a web service. Here is my code for a simple web service which returns a string.
At the beginning i inserted some code from ben nadel
It refreshes the stubfile automatically because otherwise you get errors while passing parameters.
<cfcomponent
displayname="BaseWebService"
output = "false"
hint="This handles core web service features">
<cffunction
name="Init"
access="public"
returntype="any"
output="false"
hint="Returns an initialized web service instance.">
<cfreturn THIS />
</cffunction>
<cffunction
name="RebuildStubFile"
access="remote"
returntype="void"
output="false"
hint="Rebuilds the WSDL file at the given url.">
<cfargument name="Password" type="string" required="true" default="" />
<cfif NOT Compare(ARGUMENTS.Password, "sweetlegs!")>
<cfset CreateObject("java", "coldfusion.server.ServiceFactory"
).XmlRpcService.RefreshWebService(
GetPageContext().GetRequest().GetRequestUrl().Append("?wsdl").ToString()) />
</cfif>
<cfreturn />
</cffunction>
<cffunction
name="easyService"
access="remote"
returntype="any"
output="false">
<cfargument name="anyOutput" type="string" default="this and that" />
<cfargument name="xtype" type="string" required="yes" default="1" />
<cfif Compare(xtype, "1") EQ 0>
<cfset anyVar = "one" />
<cfelse>
<cfset anyVar = "two" />
</cfif>
<cfreturn anyVar>
</cffunction>
</cfcomponent>
Here I am trying to invoke the webservice.
<cfinvoke
webservice="https://[...]/Components/Webservice.cfc?wsdl"
method="RebuildStubFile">
<cfinvokeargument
name="Password"
value="sweetlegs!" />
</cfinvoke>
<cfinvoke
webservice="[...]/Components/Webservice.cfc?wsdl"
method="easyService"
returnVariable="anyVar" >
<cfinvokeargument
name="xtype"
value="2"
omit="true">
</cfinvoke>
<cfdump var="#anyVar#">
The first method of my web service component can be invoked but the second one always returns this error message:
coldfusion.xml.rpc.ServiceProxy$ServiceMethodNotFoundException: Web service operation easyService with parameters {xtype={2}} cannot be found.
at coldfusion.xml.rpc.ServiceProxy.invoke(ServiceProxy.java:149)
at coldfusion.runtime.CfJspPage._invoke(CfJspPage.java:2301)
at coldfusion.tagext.lang.InvokeTag.doEndTag(InvokeTag.java:454)
If i type in the url of the webservice, by adding
?method=easyService&xtype=2
it returns the right value. but this is like passing values with a GET method.
i have been searching for hours and don't know where the problem occures.

I think when using WebService call you need to specify all arguments and use omit="true" on the proper one (not on xtype).
<cfinvoke
webservice="[...]/Components/Webservice.cfc?wsdl"
method="easyService"
returnVariable="anyVar" >
<cfinvokeargument
name="anyOutput"
value=""
omit="true">
<cfinvokeargument
name="xtype"
value="2">
</cfinvoke>
