<?xml version="1.0" encoding="UTF-8"?>
<entry xmlns="http://www.w3.org/2005/Atom" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xml:base="http://localhost:8080/odata/v2/">
   <id>http://localhost:8080/odata/v2/Orders(101)</id>
   <title type="text">Orders</title>
   <updated>2021-04-19T13:33:17.097+03:00</updated>
   <category term="org.apache.olingo.odata2.ODataOrders.OrdersType" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" />
   <link href="Orders(101)" rel="edit" title="OrdersType" />
   <content type="application/xml">
      <m:properties>
         <d:Id>101</d:Id>
         <d:Customer>John</d:Customer>
      </m:properties>
   </content>
</entry>

2. In the logs you should see the line:

which comes from the callback handler OrdersHandler.js, which is configured in the OData descriptor Orders.odata
