JavaEE - TomEE (Tomcat v9.0) - 尝试了无效的生命周期转换([before_destroy])

Question

我是 JavaEE 的新手，完全不知道这个问题。我尝试在 TomEE Plume 8.0.0 服务器上运行我的项目，但我就是无法让它工作。我尝试了很多不同的东西，主要是到处搜索，但我仍然对导致这个问题的原因感到困惑。这是我不断遇到的严重错误:

接着是一堆关于无法部署我的 sessionBeans 的错误，然后就告诉我它无法运行。

请问找出问题所在的最佳方法是什么？

我正在使用最新的 Eclipse EE (20180917-1800)，运行 Linux Mint 19 Tara，java-11-openjdk-amd64 链接到项目。

编辑:好吧，我尝试了各种版本的 OpenJDK，甚至是最新的 JRE，但在这个问题上我仍然一头雾水。任何帮助将不胜感激。

Answer 1

我知道这是一个老问题，但我通过谷歌搜索发现了同样的问题。

我只是通过在启动 TomEE 之前确保我的数据库正在运行来解决问题。如果没有正在运行的数据库，JPA 将无法工作。
