Question

I have this response from a Java web service:

HTTP/1.1 200 OK
Date: Mon, 23 Apr 2012 12:08:50 GMT

--MIMEBoundaryurn_uuid_14B7343BF98675BB5D1335182931028--

The exception from WCF is telling me The data at the root level is invalid. Line 1, position 1.

My app.config is as following:

<customBinding>
  <binding>
    <!--<messageModifier />-->
    <!--<mtomMessageEncoding messageVersion="Soap11" writeEncoding="utf-8" />-->
    <textMessageEncoding writeEncoding="utf-8" messageVersion="Soap11"   />
    <httpsTransport
      requireClientCertificate="false"
      transferMode="Buffered" />
  </binding>
</customBinding>

As you can see I already tried different settings like mtom/text encodig, soap11/soap12 for message version, buffered and responseStreamed for transferMode. I’m kind of stuck. When I strip some of the response with Fiddler I got it working:

Am I missing something? Is there a magic combination of config settings I need?

I also tried bot the IClientMessageFormatter and the IClientMessageInspector but they both seem to be too high in the stack because WCF already fails with the ProtocolException telling The data at the root level is invalid. Line 1, position 1..

I hooked in the ChannelMessageInterceptor from the WCF sample. I thought I got that working but now I’m getting exceptions from the java service:

At least it is telling me they’re using Axis? I’ve also seen exception messages telling me the content type of the response doesn’t match the type from the binding, but I cannot reproduce them at this time.

It looks a lot like this question. I also tried the WCF Soap With Attachments Encoder but it also keeps nagging the Data at the root level is invalid. Line 1, position 1. (but now directly inside a XmlException rather than a ProtocolException).

Update
I have the WCF SWA working!

An example message including an attachment:

At the moment I’m thinking about invoking the service with a HttpWebRequest because the parsing is much less error prone.

When using the default MTOM Encoder for this specific message it works :S Now I need to dynamically switch encoders?!

I finally got it working. Based on the WCF SWA sample I created a binding extension which uses the TextMessageEncodingBindingElement as default and for sending messages and a fallback mechanism using the MtomMessageEncodingBindingElement when receiving multipart/related messages.

Thank you all.

Answer 1

This soap is formatted like a mime message but in practice there are not attachments. If you have a sample that does contain attachment please publish. Otehrwise I assume tehre are never attachments and I would advise you build your own message encoder that simply strips everything except the soap envelope.
