MTOM issue? : MIME part with Content-ID not found

Question

Hello.

I'm stacking on the problem that might be MTOM or Java-.Net Interoperability issue.
I found this thread asking same error "MIME part with Content-ID '...' not found"
http://forums.microsoft.com/msdn/ShowPost.aspx?siteid=1&postid=3768026

In the case of me, server isn't Cassini, but same problem happened.

Program called web service to download a file from server with MTOM.
Error message was "MIME part with Content-ID 'Content-ID 'cid:3a5779b3-3aec-4a80-89d5-6f6ece79522d@http%3A%2F%2Fcxf.apache.org%2F' not found.

 

Server : Apache CXF 2.1.2 - MTOM enabled
Client : Visual C# 2008 Express Edition sp1 - simply added service reference.

I removed annotations, @MTOM and  @XmlMimeType("application/octet-stream"),
from server-side program, then programs worked fine, it is not using then MTOM though.

 

I'm not .Net expert and I'm not sure which side, client-side or server-side, has problem.
I need to add any configrations in app.config?
Can anyone give me any suggestions about this problem?
 
Thanks.

 

Answer 1

this goes before the first part of the message,

Content-ID: http://tempuri.org/0

Then inside that XML it says something like:
<xop:Include href="cid:http%3A%2F%2Ftempuri.org%2F1%2F633928716725468750"

The content ID for the MTOM part must have the same tag:
Content-ID: <http://tempuri.org/1/633928690345781250>

Whatever the number is in the XOP string must match the following MIME part.
