requirejs loading not work

[molyland]

I added x2js on my bower.json file

"x2js": "~1.2.0"

Then add in my main.js requirejs config file

paths: {
'x2js': '../vendor/x2js/xml2json.min'
....
}

shim: {
   'x2js' : {
          exports : 'X2JS'
        },
....
   'admin-lte' : {
          deps: [
            'jquery', 
            'jquery.bootstrap', 
            'toastr', 
            'bootstrap-datepicker',
            'jquery.transform',
            'x2js'
          ]
        }
}

In my script

var x2js = new X2JS();
var json_obj = x2js.xml_str2json(xml_str);
console.log('module [json obj]: ', json_obj);

I've this error:

ReferenceError: X2JS is not defined
