Question

尝试将EAR文件部署到websphere 8.5.0.1时，我遇到了这个问题。 EAR仅包含其依赖项

共享记录-1.1.3.jar，的log4j-1.2.17.jar

和一个JSF页面。作为注释，默认情况下，类路径中必须是common-loggins副本，因此删除库不是一个选项。当初始化服务器提供myfaces库时需要进行公共日志记录。堆栈跟踪粘贴在底部。应用程序和我们的模块类加载器被设置为父级。

任何帮助都将受到高度赞赏

Answer 1

由于这个原因，WAS利用apache公共日志记录在您的EAR中使用它，使用Parent Last策略打破运行时一致性并获得该异常。

我建议您从应用程序中删除该jar以使用提供的WAS。有关详细信息： Configuring applications to use Jakarta Commons Logging

Answer 2

可能是你在类路径上有2个版本的commons-logging jar。删除其中一个。

在websphere 8.5.01上部署时，Log4JLogger不实现Log
