酒井20.1与scorm需要帮助解决NPE和其他错误的堆栈跟踪问题

问题描述

好吧，我对此一无所知。我一直在尝试在具有几个子模块的测试服务器上部署Sakai 20.1。我非常有信心可以与评估和认证工具一起使用。然后，当我尝试添加SCORM时，一切都发生了。 Tomcat启动（我可以在localhost：8080看到tomcat主页），但是Sakai页没有启动。我回去删除了子模块，并使用干净的tomcat重新开始。一切都很好。然后再试一次，只是点了一下。仍然大致相同的问题。 启动Tomcat的Java窗口文本中有很多错误。 tomcat文件夹中的日志中有很多错误。太多了，我什至不知道从哪里开始。

以下是顶部的一些内容，其中包括似乎是表演停止因素的大内容。

我在其他地方发布了此消息，并被要求提供一些细节，因此我还将在这里分享：

• 您正在运行什么版本的Tomcat？ 运行tomcat 9.0.33

• 您将SCORM Player的哪个分支部署到了20.1实例？ 我从20.x分支的20.0标签创建了https://github.com/sakaicontrib/SCORM.2004.3ED.RTE.git的本地分支。唯一的本地差异是将pom.xml文件中的版本从20.0更改为20.1。

• 您是否尝试过清理Tomcat并进行完全重新部署？ 是的，我已经尝试过完全重新部署。那是我工具箱中很少的工具之一。

• 您是否已打开auto.ddl？ 我不知道。我必须调查一下然后再给您回复。

• 您正在使用MySQL还是Oracle？ 使用MySQL 5.6版

任何帮助将不胜感激。

我找不到附加日志文件的方法，但是应该可以访问它们here
