使用Adobe Experience Manager的Ne tdiagnostics Java代理启动错误

问题描述 投票：0回答：1

[我们正在使用Adobe Experience Manager，我需要通过javaagent对其进行设置（我们有一个称为netdiagnostics的用于Java应用程序监视的特殊工具）。通常，为了启用监视，我只需要通过javaagent选项将netdiagnostics的参数传递给应用程序。但是将javaagent选项传递给Adobe Experience Manager之后，它无法启动，并且我在日志中看到错误：

我发现了类似的问题，但与另一个代理商：https://discuss.elastic.co/t/apm-java-agent-startup-error-with-adobe-experience-manager/153451

如该问题中所述，我试图通过命令行传递sling.bootdelegation参数（“ -Dsling.bootdelegation.com.cavisson = com.cavisson。*”），但是没有运气。

而且，AEM在没有javaagent选项的情况下也成功启动了...

在sling.properties中设置启动代理属性无法正常工作。我也得到了与您相同的NoClassDefError。您应该尝试将此属性与javaagent选项一起设置。javaagent：agent.jar -Dorg.osgi.framework.bootdelegation = com.cavisson.ndutils -jar sling.jar希望这会有所帮助。
