dotnet web services enhancements : The message must contain a wsa:To header

I am using WSE 2 SP3 and receiving the following error from my client calling
a secure service using client certificates. When I setup the policy, I
required signing and encryption for the request and response.

System.Web.Services.Protocols.SoapException: Server was unable to process
request. ---> The message must contain a wsa:To header.
at
System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)

methodName, Object[] parameters)

correlationId, String messageBody, String userName, String applicationName,
String instance, String postBackUrl)
at DellWSE2SP3.ConsumeDellMSS.Dispatch(String messageType, String

Hi Chris,

Did you check if the wsa:To header is being sent to the server ? (Using the
trace file).
Maybe, the client is not applying the WSE policy at all because of an
difference in the mapping.

My client app is not generating a trace file. In fact, I have been able to
create a service and a test client that consumes this service using WSE2 SP3
and client side certs and it works fine, but still no trace file in either
app. The web.config looks fine to me, and permission wise their should be no
problem. The event log is also empty. So I need to divert and fix that
problem before I can see if the header is missing in the trace....

.... <microsoft.web.services2>
<security>
<x509 storeLocation="CurrentUser" allowTestRoot="true" />
</security>
<diagnostics>
<trace enabled="true" input="InputTrace.webinfo"
output="OutputTrace.webinfo" />
<policyTrace enabled="true" input="ReceivePolicy.webinfo"
output="SendPolicy.webinfo" />
</diagnostics>
<policy>
<cache name="policyCache.config" />
</policy>
</microsoft.web.services2>
</configuration>

I would assume that my problem with the missing wsa header is that the
client is not setup the same way as the service (response/response
signing/encryption). I'll need to talk to the customer to understand what
options I should select while going through the WSE 2 wizard.

Off topic, but shouldn't all this information be part of the web service
contract (WSDL)? Be nice if I could just read my customer's WSDL to get all
this information.

How can I check that the WSE is running? My code is using the WSE2 assembly
and is successfully calling my service? I did install WSE3 first, then later
down the road had to install WSE 2 SP3...so both are running but that should
not be a problem. I also made sure that all my WSE2 code is running under
framework 1.1 in IIS.

Puzzled.

mmm, that is strange. If a trace file is not being generated, perhaps WSE is
not running at all.
No, WSDL does not say anything about the WS-* stack, that's why the
WS-Policy spec was designed. However, only WCF implements that spec for the
moment.

Pablo Cibraro.
