ColdFusion Component or Interface WebService

Does anybody knows why I have this error?

This is working in my development environiment, but I can make it works on my production server

Any help is very well come...

____________________________________________________________________________

Could not find the ColdFusion Component or Interface WebService.wsListaMaterial.

Ensure that the name is correct and that the component or interface exists.

The error occurred in C:\inetpub\wwwroot\virtual\SubRotinas\eConsultaLM.cfm: line 84
82 : <cfif Parm1 eq "LeLM" AND (Len(wPartNumber) GT 1)>
83 :     <cfinvoke component="WebService.wsListaMaterial" method="RevisaoAtual" returnvariable="Resultado">
84 :         <cfinvokeargument name="PartNumber" value="#wPartNumber#">
85 :     </cfinvoke>
86 :  <cfset wListaMaterialId = Resultado.ListaMaterialId>

This is the way I register the web service
