                {
                    type: "text"
                },
                {
                    type: "text"
                },
                {
                    type: "text"
                },
                {
                    type: "text"
                },
                {
                    type: "text"

As your are using two urls one from Sajaxsource and othe inside ajax ,you dont have to use ajaxsource in this case

<script type="text/javascript">

//this is the datatable it brings data in json format from server
$( document ).ready(function() {
var selected=$("#mainschool_id option:selected").val();
//alert(selected);
$('#example').dataTable({
       "bProcessing": true,
             "ajax": {
            "url": "/nvs/system/modules/NVS.NLI/elements/trainingalldatatable.jsp",
            "data":{data:selected}

            },

               "search": {
                 "smart": false
               },
               "scrollX": true,
       "aoColumns": [
           { type: "text"},
           { type: "number"},
           { type: "text" },
           { type: "text" },
           { type: "text" },
                       { type: "text" },
                       { type: "text" },
                       {type:"text"},
                       { type: "text" },
                       { type: "text" },
                       { type: "text" },
                       {type:"text"},
                        {type:"text"}



              ]
      });
});
</script>

I hope it helps thanks.
