Hi
I am calling a web service using a proxy class generated using wsdl.exe
Does anyone know what the error I get means?
Is the namespace mentioned below part of the response I get from the web
service?

Exception:System.InvalidOperationException: Namespace prefix 'AWE' not
defined
at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadFaultCode(XmlReader
reader)
at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadSoapException(XmlRe
ader reader)
at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClient
Message message, WebResponse response, Stream responseStream, Boolean
asyncCall)
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String
methodName, Object[] parameters)
...

Thanks

Greg

Hi,

Can you send the code snippet?
Couldn't guess anything from your error message. :-(

Looks like the non .net web service returns a fault, but the response is
not a well-formed xml: the "AWE" alias is not defined in the
<soap:Envelope> scope.
Just to make sure that tat is the case we need to look at the SOAP trace of
the response received by the client.

Thanks,
Elena
