fnReloadAjax is not reading fnPagingInfo

Hi everyone,

I am new to Datatable. I am unable to get the pagination for my datatable: I am getting an error :
WARN::/pm-new/appadmin/retriveAdminCode.do
java.lang.NumberFormatException: null

The scenario is I should get the data in datatable according to the selected dropdown, So I used "fnReloadAjax" once I select an option from the dropdown,

i.e, function GetSelectedItem(codeType) {
$('#getAdminCode').dataTable().fnReloadAjax('retriveAdminCode.do?codeTypeId=' +codeType);
};

And In my .js file I have added,
$.fn.dataTableExt.oApi.fnReloadAjax = function ( oSettings, sNewSource, fnCallback, bStandingRedraw )
{
if ( typeof sNewSource != 'undefined' && sNewSource != null ) {
oSettings.sAjaxSource = sNewSource;
}

// Server-side processing should just call fnDraw
if ( oSettings.oFeatures.bServerSide ) {
this.fnDraw();
return;
}

this.oApi._fnProcessingDisplay( oSettings, true );
var that = this;
var iStart = oSettings._iDisplayStart;
var aData = [];

this.oApi._fnServerParams( oSettings, aData );

oSettings.fnServerData.call( oSettings.oInstance, oSettings.sAjaxSource, aData, function(json) {
/* Clear the old information from the table */
that.oApi._fnClearTable( oSettings );

/* Got the data - add it to the table */
var aData = (oSettings.sAjaxDataProp !== "") ?
that.oApi._fnGetObjectDataFn( oSettings.sAjaxDataProp )( json ) : json;

for ( var i=0 ; i
