【问题描述】：
我遇到了一个奇怪的问题。我已经为 JmDNS 3.1.6 创建了一个 OSGi 包，并且已经在 Equinox 中成功地使用它来发布服务近两年了。我最近迁移到 Apache Felix。不幸的是，相同的 JmDNS 捆绑包，即使安装没有问题，似乎也不再导出任何服务。这是我用来发布服务的代码
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() + ")");
}
}
在我的 Mac 上使用 Bonjour 浏览器，我可以看到没有发布任何服务，即使上面的代码执行时没有任何异常。以下是 Felix 对我已安装的捆绑包的评价。

我搜索了有关如何在 OSGi 中使用 JmDNS 的一般教程，但在网上没有找到任何内容。如果有人能就问题可能是什么给我提示或指出有用资源的方向，我将不胜感激。
提前感谢您的帮助和欢呼， 乔治
编辑：我现在已迁移到 maven 存储库中的 JmDNS 3.2.2 并在 Felix 中使用它。我不再直接使用 javax.jmdns.impl 中的类，如我之前的帖子所示（我已经更新了上面的源代码清单）。但是，仍然没有运气。 JmDNS 似乎以某种方式工作。我已将 JmDNS 的日志记录级别设置为最好 - 这是我得到的摘录。
