JQuery DataTables update cells

1) on client side,


var oTable2 = $('#example').dataTable().makeEditable({
sUpdateURL : "updateUser.do",
"aoColumns" : [ {}, null, null, null, null ]   // null means this column is not allowed to edit
});

2) on servlet side,


@RequestMapping(value = "/updateUser.do", produces = "application/json")
public @ResponseBody
String updateUser(@RequestParam String value, @RequestParam String id) {
String method = "updateUser";
info(method, "recieved updating record:[value]=" + value + ",[id]="
+ id);
                // update data in db
                 ...............
// if success, return the exact the same value back
// return value;
//if false, return error msg directly
return "failed to update";
}

3) actual result if failed to update
