java - 如何从 apache derby 读取错误消息 'database not found'？

Question

我通常使用其他语言进行编程，但这几乎是我第一次接触 Java；我被要求理解以下错误日志，该日志来自使用 apache derby 的程序。

我发现问题出在线路上

java.sql.SQLException: Database '/infermeria' not found.

但是读完之后

• https://db.apache.org/derby/docs/10.6/getstart/cgstutorialintro.html
• How to read Apache Derby database log?
• Database not found error in Apache Derby

我仍然无法判断我面临的是纯粹的路径问题还是更深层次的错误。

所以我尝试了最幼稚的技巧，将 infermeria.jar 复制到每个目录中，但仍然不起作用。

因此问题来了:这样的日志足以检测问题吗？

感谢您的回复!!

它看起来与 this 非常相似问题。

尝试指定数据库的完整路径:“jdbc:derby:/path/to/my/db/infermeria”。
