私はすでにグーグルなどで多くの研究をしてきましたが、私の問題に対して良い答えを得ることができず、同じ問題またはほとんど同じ問題を抱える多くの人々を見てきました。

Anuj Patel · Answer

ビルドパスにjarファイルを追加する必要があります。

commons-dbcp-1.1-RC2.jar

またはそのバージョン.. !!!!

[〜＃〜] added [〜＃〜]：ビルドパスにcommons-pool-1.1.jarが含まれていることも確認してください。

[〜＃〜] added [〜＃〜]：申し訳ありませんが、jarの完全なリストが遅れました...バージョンの衝突があるかもしれません。単なる仮定。

nicholas.hauschild · Answer

スタックトレースによると、次の行のように、アプリがorg.Apache.commons.dbcp.BasicDataSourceを見つけられないという問題があります。

Java.lang.ClassNotFoundException: org.Apache.commons.dbcp.BasicDataSource

Jarのリストにcommons-dbcpがあるようですが、なんらかの理由で、アプリがBasicDataSourceクラスを見つけていません。
