        JsonObject json = new JsonObject();

        json.loadFile("qa_data/json/valuesAsNames.json");

        // Imagine we have JSON such as the following:

        // {
        //   "1680": {
        //     "entity_id": "1680",
        //     "type_id": "simple",
        //     "sku": "123"
        //   },
        //   "1701": {
        //     "entity_id": "1701",
        //     "type_id": "simple",
        //     "sku": "456"
        //   }
        // }
        //

        // This presents a parsing problem because the member names, such as "1680"
        // are not keywords.  Instead they are data values.  We don't know what they
        // may be in advance.

        // To solve, we iterate over the members, get the name of each, ...
        int numMembers = json.getSize();
        for (int i = 0; i < numMembers; i++) {
            String name = json.nameAt(i);

            System.out.println(name + ":");
            JsonObject jRecord = json.objectAt(i);

            System.out.println("entity_id: " + jRecord.stringOf("entity_id"));
            System.out.println("type_id: " + jRecord.stringOf("type_id"));
            System.out.println("sku: " + jRecord.stringOf("sku"));

            jRecord.close();
        }
    }
