Question

这是我在线显示当前用户朋友的代码。

        final String me = "hieugioi@xxx.xxx.x.xx";
        connection.connect();
        connection.login(me, "123456");
        final Roster roster = connection.getRoster();

    final Collection<RosterEntry> entries = roster.getEntries();
    for(final RosterEntry entry : entries) {
        System.out.println("User: " + entry.getUser());
        System.out.println("Name: " + entry.getName());
        //System.out.println("Status: " + entry.getStatus());


        final Presence p = roster.getPresence(entry.getUser());
        System.out.println("====== Mode: " + p.getMode());
        System.out.println("====== Status: " + p.getStatus());
    }

事实上，用户hieutot和hieungoan在Openfire中在线，但它始终显示为NULL！我的代码出了什么问题？
