在Websphere 8.5.01上部署時，Log4JLogger不實現日志

Question

嘗試將EAR文件部署到Websphere 8.5.0.1時遇到了這個問題。 EAR僅包含其依賴項

commons-logging-1.1.3.jar，log4j-1.2.17.jar

和一個JSF頁面。 請注意，默認情況下，classpath中的目錄必須是common-loggins副本，因此不能刪除庫。 初始化服務器提供的myfaces庫時出現問題，該庫需要公共日志記錄。 堆棧跟蹤粘貼在底部。 該應用程序和我們的模塊類加載器被設置為父級。

任何幫助將不勝感激

Answer 1

為此，WAS利用apache通用日志記錄在EAR中將其與Parent Last一起使用，從而破壞了運行時的一致性，並導致該異常。

我建議您從應用程序中刪除該jar，以使用WAS提供的jar。 有關更多詳細信息： 配置應用程序以使用Jakarta Commons Logging

Answer 2

可能是您在類路徑上有2個commons-logging jar版本。 刪除其中之一。
