WSO2ESB: SOAP Action header not what expected on response - wso2

Question

Trying to figure out why my SOAP Envelope Action header is not what I expect. I am calling WSO2ESB and communicating with a another WCF service. I am using an NTLMmediator to authenticate to the backend service.
My input transaction looks like this
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

What my transaction looks like when I write it from inside my mediator and from the value of Envelope from logging in my Proxy Service after my mediator has executed. This is what I exepect the value of Action to be: GetProducesByCustomerNbrResponse
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing">
<s:Header>
<a:Action s:mustUnderstand="1">http://www.mycompany.com/services/GetProductsByCustomerNbrResponse</a:Action>
<a:RelatesTo>urn:uuid:448cb5ec-b2d8-4292-b245-5b0d42c0e52a</a:RelatesTo>

What it looks like in my wire logs is below. You can see the Action is now GetProductsByCustomerNbr instead of GetPRoductsByCustomerNbrResponse

I do not understand why I am seeing the input transaction action and not the action from the output. I am sure there is something I am missing or not doing right but I am struggling to find it. If anyone has any thoughts or can point me in the right direction I would appreciate it. If there is any information I failed to provide that would be useful please let me know and I will post it.

Answer 1

I had to add properties to my proxy in order to get this working. Below are the 2 properties I had to add.
disableAddressingForOutMessages so that the ESB was not adding WS-Addressing headers to outgoing messages
PRESERVE_WS_ADDRESSING so that the ESB will forward it on without altering the existing WS-Addressing headers
<property name="disableAddressingForOutMessages" scope="axis2" value="true"/>
<property name="PRESERVE_WS_ADDRESSING" scope="default" value="true"/>
