Служба Bonjour публикуется с JmDNS в Равноденствие, но не в Apache Felix

/ 03 августа 2011

У меня странная проблема.Я создал пакет OSGi для JmDNS 3.1.6 и успешно использовал его в Equinox для публикации сервиса уже почти два года.Я недавно перешел на Apache Felix.К сожалению, тот же пакет JmDNS, даже если он установлен без проблем, похоже, больше не экспортирует никаких сервисов.Вот код, который я использую для публикации службы 

private void publishBonjourService() {
    try {

        if (this.jmdns != null) {
            logger.config("deregistering existing service, first");
            jmdns.unregisterService(this.serviceInfo);  
        } else {
            logger.config("publishing service: \"" 
                    + bonjourServiceName + "\"");
            jmdns = JmDNS.create(InetAddress.getLocalHost(), 
                    bonjourServiceName);                
        }

        HashMap<String, Object> props = new HashMap<String, Object>();
        props.put("path", "index.html");

        this.serviceInfo = ServiceInfo.create(
                "_http._tcp.local.", 
                bonjourServiceName, 
                HttpService.WEB_SERVICE_PORT, 
                0, 
                0, 
                props);         
        jmdns.registerService(this.serviceInfo);
        logger.config("service " + bonjourServiceName 
                + " published via JmDNS");
    } catch (Exception e) {
        logger.warning("Caught exception when trying to register "
                + "Bonjour service! (" + e.getMessage() + ")");
    }
}

Использование Bonjour Browser на моем Mac. Я вижу, что ни одна служба не публикуется, хотя приведенный выше код выполняется без каких-либо исключений.Вот что говорит Феликс о моих установленных пакетах.

Я искал учебник о том, как использовать JmDNS в OSGi в целом, и не нашел ничего в сети.Буду признателен, если кто-нибудь подскажет мне, в чем может быть проблема, или укажет на полезный ресурс.

Заранее благодарю за помощь и приветствия, Георг

Редактировать: теперь я перешел на JmDNS 3.2.2, найденный в репозитории maven, и использую его в ФеликсеЯ больше не использую классы в javax.jmdns.impl напрямую, как показано в моем предыдущем посте (я обновил список исходного кода выше).Однако все равно не повезло.JmDNS, кажется, работает как-то.Я установил уровень протоколирования для JmDNS как лучший - вот выдержка из того, что я получаю.

Вы уверены в настройке?Наиболее распространенная причина проблем такого типа: Плохо настроенное имя хоста и брандмауэр.

  • Брандмауэр проще всего диагностировать, проверьте, открыт ли порт 5353 / udp.
  • Проблема с именем хоста наиболее распространена в Linux и означает, что вы прослушиваете другую подсеть, чемтот, который вы публикуете.Вы можете исправить имя хоста, указав IP-адрес при создании экземпляра JmDNS.

Как вы определяете, опубликован ли сервис или нет? Вы проверяете из другого пакета или вы проверяете из оболочки Gogo? Если первое, возможно, вы видите некоторую несовместимость пространства классов, которая фильтрует службу. Если последнее, то я не уверен. Если вы еще этого не сделали, введите «inspect s c 14» в Gogo, чтобы проверить сервисные возможности пакета 14 и посмотреть, предоставляет ли он какие-либо услуги.

Возможно, я неправильно понимаю, вы говорите о службах DNS или OSGi? Если DNS, то не обращайте внимания на мои комментарии.
