Usage

From source file:examples.nntp.MessageThreading.java

public static void main(String[] args) throws SocketException, IOException {

    if (args.length != 2 && args.length != 4) {
        System.out.println("Usage: MessageThreading <hostname> <groupname> [<user> <password>]");
        return;//ww  w . ja  v a  2 s  .  c  o  m
    }

    String hostname = args[0];
    String newsgroup = args[1];

    NNTPClient client = new NNTPClient();
    client.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out), true));
    client.connect(hostname);

    if (args.length == 4) { // Optional auth
        String user = args[2];
        String password = args[3];
        if (!client.authenticate(user, password)) {
            System.out.println("Authentication failed for user " + user + "!");
            System.exit(1);
        }
    }

    String fmt[] = client.listOverviewFmt();
    if (fmt != null) {
        System.out.println("LIST OVERVIEW.FMT:");
        for (String s : fmt) {
            System.out.println(s);
        }
    } else {
        System.out.println("Failed to get OVERVIEW.FMT");
    }
    NewsgroupInfo group = new NewsgroupInfo();
    client.selectNewsgroup(newsgroup, group);

    long lowArticleNumber = group.getFirstArticleLong();
    long highArticleNumber = lowArticleNumber + 5000;

    System.out
            .println("Retrieving articles between [" + lowArticleNumber + "] and [" + highArticleNumber + "]");
    Iterable<Article> articles = client.iterateArticleInfo(lowArticleNumber, highArticleNumber);

    System.out.println("Building message thread tree...");
    Threader threader = new Threader();
    Article root = (Article) threader.thread(articles);

    Article.printThread(root, 0);
}
