Unable to export the table as excel file

Hi,

I am using the latest stable version of data tables and table tools for my project. The UI is appearing as expected, also the pagination and search functionality is working too. However when I click the excel button no action is performed. I see no error on my browser console.

I have initialised the table as follows

$(document).ready(function(){
    $('#user_table').DataTable( {
        "dom": 'T<"clear">lfrtip',
        "tableTools": {
            "sSwfPath": "js/swf/copy_csv_xls.swf"
        }
    } );
});

This is first time I am using this plugin so I am unsure as to where the problem might be.

Kindly help.

Thanks
