我正在尝试实现一个使用轴作为其库之一的 salesforce API。当我将所需的 axis.jar 文件部署到 lib/ext 目录时，我在启动时收到以下警告，当使用 API 时，它也失败并显示“无法初始化类 org.apache.axis.components.logger .LogFactory”运行时错误显示在屏幕上。

Liferay 包含axis.jar 并使用它。如果你把它放到全局类路径中，以便你的优先于 Liferay 已经交付/测试过的路径，那么它很可能不起作用。如果没有进一步的分析，我会说很有可能是这种情况。

您可以通过删除它来测试它。我不知道我建议在 Liferay 中升级轴的步骤。由于 Liferay 不包含最新版本，我认为更新并非易事，否则可能已经完成。

当您将axis.jar部署到您的webappWEB-INF/lib目录时它是否有效？
