Getting data from Linkedin with Accesstoken using Java

Question

I already have auth token (I am confused that it is access token or authorization code) from linkedin OAuth popup. Here is the code to get the auth token

 <script type="text/javascript" src="//platform.linkedin.com/in.js">
        api_key:77ok0qpcsnr6z9
     </script>
    <script type="text/javascript">
        /*global IN*/
        IN.Event.on(IN, "systemReady", sysRed);
        function callbackFunction() {
            debugger;
            alert("oAuth Token: " +IN.ENV.auth.oauth_token);
        }
        function sysRed(){
            alert('system is ready');
            IN.User.authorize(callbackFunction);
        }
    </script>

Now I am using that token to grab the data. I am using scribejava api for the same https://github.com/scribejava/scribejava

And I ran into error when using that error.

Trading the Request Token for an Access Token...
