Hi everyone,

Thank you for helping in advance,

I got an error when debugging my JavaScript code

"Failed to load resource: the server responded with a status of 404 (Not Found)"

on the line: "xmlHttpRequest.send();"

full code:

executeRequest: function (request) {
        var xmlHttpRequest = new XMLHttpRequest();
        var response = null;
        xmlHttpRequest.open("GET", OrgDataService.getRESTUrl() + request, false);
        xmlHttpRequest.setRequestHeader("Accept", "application/json");
        xmlHttpRequest.setRequestHeader("Content-Type", "application/json; charset=utf-8");
        xmlHttpRequest.send();
        return xmlHttpRequest.responseText;
    },

    getRESTUrl: function () {
        var serverUrl = Xrm.Page.context.getClientUrl();
        return serverUrl.substring(serverUrl.lastIndexOf("/")) + "/xrmservices/2011/organizationdata.svc";
    }

Thank you again!

I suggest installing www.fiddler2.com and looking at the request that is being sent and causing the 404 - it is most likely to be that you have the incorrect entity set name - e.g. it should be AccountSet for accounts.

Hi Chris,

Try the below code, just pass the Odata query which you want to execute to the method and get back the result.

function ODataCall(oData_query)
{
    var _result = null;
    var _serverUrl = Xrm.Page.context.getClientUrl();
    var _oDataSelect = _serverUrl + "/XRMServices/2011/OrganizationData.svc/" + oData_query;

    var _retrieveReq = new XMLHttpRequest();
    _retrieveReq.open("GET", _oDataSelect, false);
    _retrieveReq.setRequestHeader("Accept", "application/json");
    _retrieveReq.setRequestHeader("Content-Type", "application/json;charset=utf-8");

    _retrieveReq.onreadystatechange = function ()
    {

        if (_retrieveReq.readyState == 4) {
            if (_retrieveReq.status == 200) {
                var _retrieved = JSON.parse(_retrieveReq.responseText).d;
                if (_retrieved.results.length > 0) {
                    _result = _retrieved.results[0];
                }
            }
        }
    };
    _retrieveReq.send();
    return _result;
}

Let me know if you are still not able to perform Odata call, thanks.
