Grailsを初めて使用しました。私はpostgresql 9.0データベースサーバとgrails 2.3.4を接続しようとしています。 postgresql-9.0-801.jdbc3.jarファイルをgrails applicationのlibフォルダに追加しました。私はIntellijエディタでアプリケーションを実行していて、その後エラーが発生しています。 どこが間違っているのですか？PostgresデータベースとGrails 2.3.4との接続方法

感謝:) をそれはあなたが私の答えをマークすることができ –
を働いたとして、[受理]（のhttp：/ /stackoverflow.com/help/accepted-answer）を参照してください。また、ログは現在の形式ではほとんど読み込みができません。最初は編集しようとしましたが、実際にはできません（次回はその点を覚えておいてください）。 –
私はそのような愚かな構成の不一致を信じることはできません。それも私のために働いたが、両方のために働くことは理にかなった –
