我正在通過框架實現Felix 5.4玩OSGi。目前我想要將一個應用程序服務器作爲一個包安裝在OSGi框架上。我已經看過Pax-web，它對我來說似乎是最完美的解決方案。 然而，在成功啓動了所有需要的軟件包，軟件抱怨，出現以下錯誤：無法啓動Pax-web

通過查看錯誤，似乎有些碼頭配置不是在PAX-嵌入式碼頭版本。特別是maxErrorDispatches,blockingTimeout和persistentConnectionsEnabled會導致錯誤。然而，即使註釋掉那些3個屬性，PAX-網頁將無法啓動（不能連接到127.0.0.1）和一些登錄後，將只打印：
org.ops4j.pax.web.pax-web-jetty-bundle[org.ops4j.pax.web.service.internal.ConfigurationImpl] : Reading configuration property org.ops4j.pax.web.config.url has failed
我試圖解決這個問題問題，但既然我既不是OSGi和Jetty的專家，也不能提出解決方案。要添加一些上下文到我的方案，這裏有一些額外的信息：
- 我使用felix 5.4;
- 我使用Windows 10 64位;
- jetty.xml我在conf /，bin/felix文件夾的同一目錄下;
- 安裝經由
java -jar bin\felix.jar

你使用哪個碼頭版本？您的套餐清單不顯示碼頭。 –
@ChristianSchneider：現在我正在使用4.3.0版本的「pax-web-jetty-bundle」。通過查看罐子內部，我發現Jetty嵌入其中：所述束的清單包含一個Export-Package條目，它聲明：org.eclipse.jetty; version =「9.2.19.v20160908」。我推斷我正在使用9.2碼頭版本;我錯了嗎？ – Koldar
