Issue in getting response back while connecting to Oracle DB in WSO2 esb

Question

I am working on sample application in WSO2 esb which connects to Oracle Database and return the response of a query. Below mentioned is my service. Issue I am facing is I am not getting the response back after execution of service.However I am able to see the value returned as a query response, but not able to render it in response document.

Can anybody suggest, what I am missing? DB credentials fields have been hashed.

You have to send back the message generated by your payloadFactory in your inSequence :

<header name="To" action="remove"/>
<property name="RESPONSE" value="true" scope="default" type="STRING"/>
<property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>
<send/>

Your mediation is "OUT_ONLY", so, your outSequence will never been executed
