wsdl problem exposing a service with servicemi-http

[Raffaele Spazzoli]

I'm trying have the following configuration

corbaservant <---> corba BC <---> jbiesb <---> servicemix-http <--->
soap client

The call execution works so i think I have correctly configured the
servicemix-http service assemby.
When I try to get the wsdl document for that service I get this from
MC4J console:
<?xml version="1.0" encoding="UTF-8"?>

and if I try <serviceurl>/?wsdl

HTTP ERROR: 404
No wsdl is available for this service

RequestURI=/Service/EchoService/

Powered by Jetty://

if I enquire the endpoint defined for the corba BC I get the following
wsdl:
