我正在尝试在新安装的 Apache Felix 容器中使用 pax 日志记录。安装了以下 bundle :

    lb

尝试启动 bundle 39(Pax 日志记录 - 服务)会导致:

我手动检查了 Pax Logging API 包 (pax-logging-api-1.8.3.jar) - 包含文件 org/ops4j/pax/logging/EventAdminPoster.class。我还检查了 API 包 (pax-logging-api-1.8.3.jar) 中的 Manifest.mf“Export-Package” 部分以 Export-Package 开头:

org.apache.avalon.framework.logger;uses:="org.apache.log ";version="4.3";provider=paxlogging,org.apache.commons.logging;uses:="o rg.osgi.framework,org.ops4j.pax.logging";version="1.1.1";provider=paxlo gging...

所以,我不知道为什么 Pax 日志服务包启动时会抛出 ClassNotFoundException。我错过了什么?

注意: bundle 26 和 33 是​​一些测试 bundle ,我在其中尝试通过 pax 日志记录使用 log4j。

最佳答案

重启felix后问题解决。现在可以启动 Pax 日志服务 bundle 了。
