  [quote]But i can see in firebug that the post to the web service was called[/quote]
  
  What does Firebug tell you about the response of the server?

  based on the values that i can see in the firebug, a newly set of data was returned based on the new parameters that was sent during the call back. also there is no error message displayed.
  
  thanks.

  Ok. It is quite difficult to see what goes wrong. The only thing I can think of is that in the original server side processing examples, it says:
  
  [code]
  "success": fnCallback
  [/code]
  
  whereas in your example, you call your own function, which then calls fnCallback
  
  [code]
  function(msg) {
  var json = $.parseJSON(msg);
  fnCallback(json);
  ....
  }
  [/code]
  
  If you do it like this, fnCallback gets different parameters than in the original examples, as jQuery itself will give 3 parameters
  
  [code]
  function success(data, textStatus, jqXHR)
  [/code]
  http://api.jquery.com/jQuery.ajax/#jQuery-ajax-settings
  
  so yo might want to change your code into
  
  [code]
  function(data, textStatus, jqXHR) {
  fnCallback(data, textStatus, jqXHR);
  ....
  }
  [/code]

  My guess is that you are always returning sEcho as 1 rather than giving DataTables back what it sends (cast as an integer for security). If it isn't that thought, then you'll need to give us a link for us to be able to off any help.

  thank you for all your suggestions. :)
  
  I was able to fix it.
  
  it turns out i was overriding a parameter that is defined by the plugin.
  
  i just cleaned up my jquery code to this:
  
  [code]
  var oTable = $("#dataTableCustom").dataTable({
  "iDisplayLength": 25,
  "bDestroy": true,
  "bProcessing": true,
  "bJQueryUI": true,
  "bAutoWidth": false,
  "bServerSide": true,
  "sAjaxSource": globalSource,
  "sPaginationType": "full_numbers",
  "fnServerData": function (sSource, aoData, fnCallback) {
  $.getJSON(sSource, aoData, function (json) {
  var parsedJSON = $.parseJSON(json);
  fnCallback(parsedJSON)
  });
  }
  });
  
  [/code]
  
  now my data table data is refreshing. :)
  
  i'm so happy. :) thank you very much for sharing your thoughts :)
