CF10 web services not "invokable" from CF9

Question

Here's my situation:
1. first server with CF10 (just upgraded) running an application with this CFC making a wsdl web service:
<cffunction name="myWS" access="remote" returntype="boolean" output="false">
      <!--- stuff.... --->
</cffunction>
2. second server with CF9.0.1 (last hotfixes) running the web service invocation like this:
<cfinvoke webservice="http://www.firstserversite.xxx/api/folder/mycomp.cfc?wsdl" method="myWS" returnvariable="LOCAL.ret">
       <cfinvokeargument name="xxx" value="#xxx#" />
</cfinvoke>
Before upgrading first server to CF10, my two application servers talked each other the right way and that was working.
Now I see this error:
"Cannot generate stub objects for web service invocation"
ERROR: Missing <soap:fault> element inFault
It sounds like WSDL generated by cf10 is not compatible with what cf9-cfinvoke does expect!
How can I workaround this?
Many thanks to you, it's very urgent!!

Answer 1

Could the first bug referenced on this page have a hand in this:

Web Services defaults to Axis 2 methods despite setting the Axis version to Axis 1 in ColdFusion Administrator.
Sounds like CF10 only serves-up Axis 2 web services rather than serving up v1 ones when it's told to?
Sadly 10.0.3 has been pulled due to it being buggy, but there should be a replacement soon.
