Error while using oData update (415 Unsupported Media Type Error)

Hi,

I am trying to use oData Update functionality. Below is the code sample. I am trying to do this on HANA instance on AWS.

var saveModel = new sap.ui.model.odata.ODataModel("http://ec2-54-213-97-224.us-west-2.compute.amazonaws.com:8000/workshop/sessiona/01/services/MarketInfo.xsodata/", true,null,null,{"Content-Type": "application/json;charset=utf-8"});

                    var oTable = sap.ui.getCore().byId('tableid');

                    var oModel = oTable.getModel();

                    var ModelData = oModel.getData();

                    for(var i = 0 ; i < 1 ; i++)

                              {

                                        var id = ModelData[i].id;

                                        var oEntry = {

                                                    "FRACTION":"4.3",

                                                    "MARKETID" : "00001",

                                                    "YEAR":"2013",

                                                    "MONTH":"08",

                                                    "INDUSTRY":"ENTERTAINMENT"

                              };

                                        var oParams = {};

                                        oParams.fnSuccess = function (){};

                                        oParams.fnError = function () {};

                                        saveModel.update("/MarketInfo('"+id+"')", oEntry, oParams);

                              }

I have set the bJSON flag to true and also set the Content -Type. However when I run the application I get 415 Unsupported Media Type Error.

Below is the trace:

The content type for request header is only application / json and this seems to be creating the problem. Please let me know how I can override the content type.

Thanks,
