I have tried many ways to do the server-side processing but still got this problem

The following is my code

JSON data packetTransmissionLogJsonData.web

{
  "iTotalRecords": 16,
  "iTotalDisplayRecords": 16,
  "aaData": [
    {
      "transmissionId": 1,
      "deviceId": "Vincent-iPhone6",
      "filename": "D://javasrc/abc/data/out/Apple.jpg",
      "packetId": "1",
      "dispatchtime": "Sep 25, 2014 4:00:10 PM",
      "receipttime": "Sep 25, 2014 4:00:11 PM",
      "chunklist": "1",
      "chunksize": 100000,
      "connectiontype": "wifi",
      "lat": 1.335507,
      "lon": 103.736957,
      "transmitterid": "null",
      "speed": 0.0,
      "cellid": "null",
      "signalstrength": 0.0
    },
    {
      "transmissionId": 2,
      "deviceId": "Noel-iPhone6",
      "filename": "D://javasrc/abc/data/out/Samsung.jpg",
      "packetId": "5",
      "dispatchtime": "Sep 25, 2014 4:00:01 PM",
      "receipttime": "Sep 25, 2014 4:00:11 PM",
      "chunklist": "5",
      "chunksize": 200000,
      "connectiontype": "wifi",
      "lat": 1.335482,
      "lon": 103.739845,
      "transmitterid": "null",
      "speed": 0.0,

    },
   ...
}
