如何從apache derby中讀取錯誤消息“找不到數據庫”？

Question

我通常使用其他語言編程，但這幾乎是我第一次接觸Java。 我被要求了解以下錯誤日志，這些錯誤日志來自使用apache derby的程序。

我看到麻煩就到了

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

但是看完之后

• https://db.apache.org/derby/docs/10.6/getstart/cgstutorialintro.html
• 如何讀取Apache Derby數據庫日志？
• Apache Derby中找不到數據庫錯誤

我仍然無法確定我是否僅面臨路徑問題或更深層次的錯誤。

因此，我嘗試了所有方法中最幼稚的技巧，即在每個目錄中復制infermeria.jar，但仍然無法正常工作。

因此出現了問題：這樣的日志足以檢測到問題嗎？

感謝您的答復！

它看起來與此問題非常相似。

嘗試指定數據庫的完整路徑：“ jdbc：derby：/ path / to / my / db / infermeria”。
