Issue with receiving response from web application

Question

Hi,
I have configured B2B with business protocol as 'Custom document document over Internet', document exchange protocol as AS2-1.1 and transport protocol HTTPS1.1 to invoke a web application deployed in Oracle Application server. B2B is able to invoke the web application with HTTPS request which contains an xml.
I have set the acknowledgment mode as 'Sync' and 'Is acknowledgement handled by B2B' as true. But while receiving the response from web application which is an xml, B2B is showing the error as
Description: Unable to identify the document protocol of the message
StackTrace:
Error -: AIP-50083: Document protocol identification error
     at oracle.tip.adapter.b2b.engine.Engine.identifyDocument(Engine.java:3244)
     at oracle.tip.adapter.b2b.engine.Engine.processIncomingMessage(Engine.java:1665)

     at oracle.tip.adapter.b2b.data.MsgListener.run(MsgListener.java:400)
     at java.lang.Thread.run(Thread.java:534)
I have added headers as present in the wire message of the request. In B2B, it is showing the wire message for response as follows.

I am able to see the HTTP response in b2b_dc_transport.log. In transport log it is not showing any error. Please help me to fix this issue.

Hi,
Request and Response should be part of same agreement. I hope you are not confused between Acknowledgement and Response. Acknowledgement can be received in the same session (sync mode) but Response will always come in a different session and will be treated as a different document. If, for request, party A is initiator and B is responder then for response party B will be initiator and party A will be responder (as Requset and Response are two docs in case of Custom Document)
For configuring X-Path, please refer section 8.3.11 Configuring the XPath Expression for a Custom XML Document at below link -

Please let us know whether you are trying to receive a response or Ack?
