InvalidOperatio nException Calling a web service

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:Syste m.InvalidOperat ionException: Namespace prefix 'AWE' not
defined

Message message, WebResponse response, Stream responseStream, Boolean
asyncCall)

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:Envelop e> 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

On a client web services request, I have a SoapExtension that is adding a header to the message in the BeforeSerialize stage. If the Web Service request is for an operation with style="document"/use="literal", everything works fine - the header is added, message is serialized and all is ok. If the Web Service request is for an operation with style="rpc"/use="encoded":

Hello all, I have a project in Visual Studio, developing a .NET application for a Windows Mobile 2003 device.

Now I get the following Exception when running the app in an emulator: InvalidOperationException

Hello, I have a .NET client that accesses a Java webservice.

For most users, this new feature is actually very convenient. If you want to control the update process,...
