JSON parsing error using JQuery-1.7.1.min.js

I am Using DataTable 1.7.5 along with JQuery-1.7.1.min.js and getting a JSON parsing ERROR. While looking through several Online forums it was suggested to upgrade the validator plugin of JQuery-1.5.1.min.js but nothing about the validator of JQuery-1.7.1.min.js.Does any body has any suggestion regarding this issue ?

Table HTML:
<table cellpadding="0" cellspacing="0" border="0" class="display" id="example" >
                    <thead>
                        <tr>
                            <th>#</th>                              
                            <th></th>
                            <th>Name</th>
                            <th>Shpr</th>
                            <th>Org</th>
                            <th>Cne</th>
                            <th>Dest</th>
                            <th>Dep Dt</th> 
                            <th>LR No</th>
                            <th>Asset No</th>
                            <th>Curr Dt</th>
                            <th>Spd km/h</th>
                            <th>Waypoint1</th>
                            <th>Waypoint2</th>
                            <th>SDA</th>
                            <th>DETA</th>   
                            <th>AMC</th>                                                        
                        </tr>
                    </thead>
                    <tbody>

                    </tbody>
</table>

Javascript:

var oTable = $('#example').dataTable({

                "aLengthMenu" : [[-1, 10, 25, 50, 100], ["All", 10, 25, 50, 100]],
                "iDisplayLength" : -1,
                "bProcessing": true,
                "bJQueryUI": true,
                "bAutoWidth": false,
                //"sScrollY": "300px",
                "sPaginationType": "full_numbers",
                "sAjaxSource": "ReportAction.do?process=home",
                "bDeferRender":true,
                "sDom": 'T<"clear"><"H"lfr>t<"F"ip>',
                "oTableTools": {
                    "sSwfPath": "<%=localrequestedURL %>media/swf/copy_csv_xls_pdf.swf"
                }       
            });

JSON Data:

result = session.createSQLQuery(sql_homepage).list();
String final_data = gson.toJson(result);
final_message = "{\"aaData\":"+final_data+"}";

1.The variable sql_homepage refers to a select query to the database. 2.The variable final_message is passed to the action class which passes the data to the JSP.

I had the same problem and it was from an invisible character that got saved to the database. It is best to use a json validator to see where your error is. I used this one: http://www.freeformatter.com/json-validator.html and this one http://jsonformatter.curiousconcept.com/

datatables is super finickey about the JSON it will parse. I has to be 100% perfect and I ended up needing to create a php function to make the JSON object string instead of just using php function json_encode
