  So, short story is that you cannot make an AJAX call to a different domain. Look at http://stackoverflow.com/questions/3506208/jquery-ajax-cross-domain for some ways to get around this restriction.

  @aaronw .... first of all , thank you to answer at my question.
  Second, if I do this (a simple ajax call in the same script):
  [code]
  $.ajax({
  type:"GET",
  url:"http://46.37.13.177:7710/WebClinicalDataAPI/GetDocumentsToValidate",
  dataType:"jsonp",
  timeout:"20000",
  crossDomain : true,
  data: {format :"jsonp"},
  success:function(json) {
  console.log ("json");
  }}});[/code]
  it's work fine!! Why?

  ok.. I have found the problem. In second case , is set [code]crossDomain : true[/code],
  question : How I can set the same in DataTable??

  Currently you'd need to use a method like this: http://datatables.net/release-datatables/examples/server_side/jsonp.html .
  
  DataTables 1.10 will include an `ajax` option which makes this somewhat easier.

  Hi Alla, first of all thank you to answer me.
  I've done what you said me ..
  [code]
  $('#tab').dataTable( {
  "bProcessing": true,
  "bServerSide": true,
  "sAjaxSource": "http://46.37.13.177:7710/WebClinicalDataAPI/GetDocumentsToValidate?format=jsonp",
  "fnServerData": function( sUrl, aoData, fnCallback, oSettings ) {
  oSettings.jqXHR = $.ajax( {
  "url": sUrl,
  "data": aoData,
  "success": fnCallback,
  "dataType": "jsonp",
  "cache": false
  } );
  }
  } );
  [/code]
  
  but now the error is :
  [quote]Uncaught TypeError: Cannot read property 'length' of undefined at jquery.dataTables.js:2038[/quote]
  
  what's wrong?

  DataTables expects a property called aaData which contains the data. Your JSON object doesn't have that. It has the data in GetDocumentsToValidate.docs.doc. You might want to use sAjaxDataProp to change aaData to what you need.

  ok but I dont understand the meaning of :
  [quote]
  "url": sUrl,
  "data": aoData,
  "success": fnCallback,
  "dataType": "jsonp",
  "cache": false
  [/quote]
  
  I must to put the value of the field or the name???

  What value of what field?
  
  The parameters for the object you highlighted are for the jQuery Ajax call and don't really have that much to do with DataTables. See: http://api.jquery.com/jQuery.ajax/
