twitter4j oauth_token comes wrong, although what's listed on app-page works perfect

Question

Let me explain my question :

In the image we can see a twitter access_token & secret (present on twitter app details page)

when I use the above two and try to update the status it works.

Twitter twitter = TwitterFactory.getSingleton();
        twitter.setOAuthConsumer(Tweet.consumer_key, Tweet.consumer_secret);
        twitter.setOAuthAccessToken(new AccessToken(u.getTwittertoken(), u.getTwittersecret()));
        twitter.updateStatus("test");

But the oauth_token & oauth_secret that I get through using twitter4j callbackURL

don't work with the above code. I always get Invalid/Expired Token error.

I don't know what can be the error. Because it used to work once, but stopped suddenly (don't know exactly when)

Please help! It'll be great if someone can share their code for both - getting & saving the token into database & then getting it again from the db to update the status.

For those who face the same error, here's what I was doing wrong :

I was trying the token & secret received in twitter-response. Although the correct method is to retrieve them from accessToken which has to be retrieved using oauth_verifier being sent in twitter-response.

ConfigurationBuilder cb = new ConfigurationBuilder();
            cb.setDebugEnabled(true).setOAuthConsumerKey(Tweet.consumer_key);
            cb.setOAuthConsumerSecret(Tweet.consumer_secret);
            TwitterFactory tf = new TwitterFactory(cb.build());
            Twitter twitter = tf.getInstance();

            RequestToken requestToken = (RequestToken) mapSession.get("rtoken");

            AccessToken accessToken = twitter.getOAuthAccessToken(requestToken, oauth_verifier);

            System.out.println("Request Token : " + ToStringBuilder.reflectionToString(requestToken, ToStringStyle.SHORT_PREFIX_STYLE));
            System.out.println("Access Token : " + ToStringBuilder.reflectionToString(accessToken, ToStringStyle.SHORT_PREFIX_STYLE));


            System.out.println(accessToken.getToken());        //use this further
            System.out.println(accessToken.getTokenSecret());  //use this further
