私は奇妙な問題に直面しています。私は JmDNS 3.1.6 用の OSGi バンドルを作成し、それを Equinox で使用してサービスを公開してから約 2 年になります。最近、Apache Felix に移行しました。残念ながら、同じ JmDNS バンドルは、問題なくインストールされたにもかかわらず、サービスをエクスポートしていないようです。サービスを公開するために使用するコードは次のとおりです

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() + ")");
    }
}

私の Mac で Bonjour Browser を使用すると、上記のコードが例外なく実行されるにもかかわらず、サービスが公開されていないことがわかります。私がインストールしたバンドルについて、Felix は次のように述べています。

OSGi 内で一般的に JmDNS を使用する方法に関するチュートリアルを検索しましたが、ネット上で何も見つかりませんでした。問題が何であるかについてのヒントを教えてくれたり、役立つリソースの方向性を教えてくれたりしてくれたら幸いです。

助けてくれてありがとう、ゲオルク

編集: Maven リポジトリにある JmDNS 3.2.2 に移行し、それを Felix で使用します。以前の投稿で示したように、javax.jmdns.impl のクラスを直接使用することはもうありません (上記のソース コード リストを更新しました)。しかし、まだ運がありません。JmDNSは何とか動いているようです。JmDNS のロギング レベルを最高に設定しました。これは、取得した内容の抜粋です。

サービスが公開されているかどうかをどのように検出していますか? 別のバンドルからチェックしていますか、それとも Gogo シェルからチェックしていますか? 前者の場合は、サービスをフィルタリングするクラス スペースの非互換性が見られる可能性があります。後者の場合、私にはわかりません。まだ行っていない場合は、Gogo で「inspect sc 14」と入力して、バンドル 14 のサービス機能をチェックし、サービスが提供されているかどうかを確認します。

おそらく私は誤解しています.DNSサービスまたはOSGiサービスについて話しているのですか? DNS の場合、私のコメントは無視してください。

設定は確かですか？このタイプの問題の最も一般的な理由は次のとおりです。 ホスト名とファイアウォールの構成が不適切です。

  • ファイアウォールは診断が最も簡単です。ポート 5353/udp が開いていることを確認してください。
  • ホスト名の問題は Linux で最も一般的であり、公開しているサブネットとは別のサブネットでリッスンしていることを意味します。JmDNS インスタンスを作成するときに、ホスト名を修正するか、IP アドレスを指定することができます。
