I have an EJB which expose some methods via WS

@Stateless
@WebService(endpointInterface = "com.icteam.loyalty.core.service.ProxyAdapterService", serviceName = "ProxyAdapterService", portName = "ProxyAdapterService",
targetNamespace = "http://www.icteam.it/loyalty", wsdlLocation = "/META-INF/wsdl/ProxyAdapterService.wsdl")
public class ProxyAdapter extends AbstractWebService implements ProxyAdapterServiceLocal, ProxyAdapterServiceRemote { ... }

This EJB implements those inner interfaces

@WebService(name = "ProxyAdapterService", targetNamespace = "http://www.icteam.it/loyalty")
@SchemaValidation
@SOAPBinding(style = Style.DOCUMENT, use = Use.LITERAL, parameterStyle = ParameterStyle.WRAPPED)
public interface ProxyAdapterService extends IWebService {

@Remote
public interface ProxyAdapterServiceRemote extends ProxyAdapterService {
}

@Local
public interface ProxyAdapterServiceLocal extends ProxyAdapterService {
}

@WebMethod
@WebResult(name = IResult.RESULT)
MemberInfoResult getMemberInfo(@WebParam(name = OPERATION_PARAM) OperationParam operationParam);
...
}

The EJB and the interfaces are in an ejb jar and a lib jar inside an ear.
The wsdl specified is in the directory META-INF/wsdl of the ejb jar file.
When I deploy the ear on jboss-as-7.1.1.Final I got this messages in the server.log

12:17:39,130 INFO [org.jboss.wsf.stack.cxf.metadata.MetadataBuilder] Add Service

The wsdlLocation is always null and the static wsdl provided isn't recognized by the AS, it still continue to deploy the dynamic wsdl.
I try to put the attribute wsdlLocation in the interface but still not working.
