    public static void main(String[] args) {
        // gets Twitter instance with default credentials
        Twitter twitter = new TwitterFactory().getInstance();
        try {
            ConfigurationBuilder cb = new ConfigurationBuilder();
            cb.setDebugEnabled(true)
              .setOAuthConsumerKey("***")
              .setOAuthConsumerSecret("***")
              .setOAuthAccessToken("***")
              .setOAuthAccessTokenSecret("***");
            TwitterFactory tf = new TwitterFactory(cb.build());
            Twitter twitter1 = tf.getInstance();
            List<Status> statuses;
            String user;
            if (args.length == 1) {
                user = args[0];
                statuses = twitter1.getUserTimeline("ATT");
            } else {
                user = twitter1.verifyCredentials().getScreenName();
                statuses = twitter1.getUserTimeline();
            }
            System.out.println("Showing @" + user + "'s user timeline.");
            for (Status status : statuses) {
                System.out.println("@" + status.getUser().getScreenName() + " - " + status.getText());
            }
        } catch (TwitterException te) {
            te.printStackTrace();
            System.out.println("Failed to get timeline: " + te.getMessage());
            System.exit(-1);
        }
    }
}

I suspect that if you reverted your change of:

statuses = twitter1.getUserTimeline("ATT");

to:

statuses = twitter1.getUserTimeline(user);

and invoked GetUserTimeline with ATT as a command line argument it should work.

It looks like the twitter4j examples come with utility scripts to execute them, so it seems you should be able to just run:

$ getUserTimeline.sh ATT
