you need to add an Echo component, set the payload to the value you are looking for and add a HTTP Response Builder with status="200"
and contentType="application/json"
.
Add the following lines after </jdbc-ee:outbound-endpoint>
and before </flow>
<response>
<http:response-builder status="200" contentType="application/json" doc:name="HTTP Response Builder"/>
</response>
<response>
<set-payload value="{"Body":{"Datalist":{"Data":"Successfully Rows inserted"}},"Status":"200"}}" doc:name="Set Payload"/>
</response>
<echo-component doc:name="Echo"/>
