Soap-proxy :soap content error from NET client

Hi Expert,

We created an SOAP-Proxy scenario and everything is tested in SOAPUI tool

successfully. But when .NET client try to send SOAP message with

PDF attachment, it has error said:java.io.IOException: invalid content

type for SOAP: APPLICATION/DIME . I am not sure if there is something we need to change on our PI side to allow contect type "application/dime" or this is truly on client side problem. Please help us! Thanks in advance!

The error is:

java.io.IOException: invalid content type for SOAP: APPLICATION/DIME
