How to use different asmx in different sub-directories ?

Hi,

I try to create one application and different virtual sub-directories (?)
with their own webservices but I have this kind of error : unable to create
the type myNamespace

Ligne 1 : <%@ WebService Language="c#" Codebehind="myClass.asmx.cs"
Class="myNamespace" %>


When all the webservices are in the same web application (same directory)
it works ...

Has someone an idea?

Thanks
