Below is the error i got from web service response.

javax.xml.soap.SOAPException: MTOM Attachments Processing Failed: Cannot de-serialize the input MIME Stream; value of the ‘type’ parameter of the ‘Content-Type’ header of the MIME message is not equal to ‘application/xop+xml’

Any idea on this?

I am thinking there is some mismatch with the content type.

Can you share your flow logic for this to better suggest you. Also which wM version ? Make sure you have updated fix levels on your IS.

Thanks,

Am checking the fix level and will comeback. Thanks Man.

The content-type for the MIME part of the attachment must be: application/xop+xml
The client application that’s creating the MIME need to be reviewed.
