我在 netbeans 中创建了一个 java 应用程序，它读取 csv 文件并使用休眠 ORM 将数据插入 SQL DB。当我从 IDE 运行应用程序时，Java 应用程序运行良好并将记录插入数据库。但是如果我将项目编译成 JAR 文件并在命令提示符下运行它，那么我会收到以下错误。非常感谢任何帮助，因为我是 Java 新手，所以我无法弄清楚是什么导致了这个问题。

这是会话的代码

    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();

这是我从命令提示符运行时遇到的异常

我发现了这个问题，我签署了 jar 文件并从命令提示符处执行它，这导致了问题。如果我在没有签名的情况下运行 jar 文件，它可以正常工作！
