AJAX with WEB SERVICE (ASP.NET)

MagX8

I'm trying to connect ajax with ASP but i don't have results.

this is my web service:

[WebMethod]
public string getEmpresaTablas()
{
string sResult = "";

        try
        {

            int nDraw = Convert.ToInt32(HttpContext.Current.Request.Params["draw"]);
            List<Empresa> lst = Empresa.getEmpresa();

            ReturnData oResult = new ReturnData();
            oResult.draw = nDraw;
            oResult.recordsTotal = lst.Count;
            oResult.recordsFiltered = lst.Count;

            foreach (Empresa o in lst)
            {
                oResult.data.Add("[");
                oResult.data.Add('"'+o.idEmpresa.ToString()+'"'+",");
                oResult.data.Add('"' + o.razonSocial.ToString() + '"' + ",");
                oResult.data.Add('"' + o.nombre.ToString() + '"' + ",");
                oResult.data.Add('"' + o.email.ToString() + '"' + ",");
                oResult.data.Add('"' + o.fono.ToString() + '"' + ",");
                oResult.data.Add('"' + o.fecha_creacion.ToString() + '"' + ",");
                oResult.data.Add('"' + o.fecha_modificacion.ToString() + '"' + ",");
                oResult.data.Add('"' + o.rut.ToString() + '"' + ",");
                oResult.data.Add('"' + o.fecha_inicio.ToString() + '"' + ",");
                oResult.data.Add('"' + o.fecha_termino.ToString() + '"');
                oResult.data.Add("],");
            }

            sResult = oResult.ToString();

        }
        catch (Exception err)
        {
            string sMsg = err.Message;
            sResult = "";
        }

        return sResult;
    }

This is my ajax

$(document).ready(function () {
$('#tblData').dataTable({
"processing": true,
"ajax": "AdministrarEmpresa.aspx/getEmpresaTablas"
});
});

With "server side" parameter, don't conect to webservice

without "server side parameter" connect to webservice but throws an error (invalid format json)

http://es.zimagez.com/zimage/screenshot1493.php

I did ajax with txt file with json ,with the same format json that throws the method "getEmpresaTablas" perfect work. but connect to webservice throw error.

this is a txt file.
