【问题描述】：
我遇到了服务器崩溃，正在尝试将 grails Web 应用程序重新部署到新服务器上。我已经安装了 Tomcat7 和 Java 并部署了 war 文件，但我的应用程序无法启动。
以下来自stacktrace.log：

虽然旧系统无法启动，但我确实有可用的硬盘驱动器，并且我检查了两个系统上的 spring jar 文件是否是相同的版本，从我可以告诉 tomcat 配置的情况来看，虽然不相同，但本质上是相同（主要是不同的 catalina 主目录和基本目录）。我相信旧系统是 Ubuntu 14，新系统是 Ubuntu 20.04
原来的开发人员不再和我们在一起了，当涉及到 java/grails 等时，我几乎只是一个系统管理员，所以任何适合新手的输入将不胜感激。
