Glassfish で組み込み derby を使用するのは賢明ですか? はいまたはいいえの場合、その理由は何ですか?
Glassfish で組み込み derby を使用する場合、JDBC 接続プールを構成する必要がありますか? はいの場合、それについての良いチュートリアルはありますか? 私はそれを見つけようとしていますが、まだ運がありません。
Web アプリケーション Embedder Derby と通常の Derby のどちらをデータベースとして使用する必要があるかを理解しようとしています。
たとえば、リソース タイプ java.sql.Driverとデータソース クラス名 org.apache.derby.jdbc.EmbeddedDriverを使用して JDBC 接続プールを構成しようとすると、次のエラーが発生します。
