无法将 SQL 服务器连接到 Jakarta 应用程序
Can'l connect SQL Server to Jakarta Application
我在雅加达世界还很陌生。我正在尝试做一个简单的 Rest API 连接到 SQL 服务器。应以 JSON 格式显示的简单实体。当我尝试使用 Glassfish 服务器应用程序部署应用程序时，出现以下错误：

我应该怎么做才能解决这个问题？
P.s.: 我忘了说我在 Intellij 上工作，我已经将 Intellij 连接到 sql 服务器
我通过重新创建 sql 服务器与 glassfish 应用服务器的连接、重新创建连接池和数据源解决了这个问题。那里出了点问题，但我不知道出了什么问题。
