タペストリーで休止状態の継承を使用しようとしていることを除いて、すべてが正常に見えます。

ライブラリの場合、どちらを削除する必要がありますか？これは親子の継承が休止状態の問題になると思いますか？チュートリアルが言うように私はそれを正しくやったと思います

Hibernate は、3.5 として、および hibernate-support を介して説明のつかない 3.x (hibernate3.jar) として、クラスパスに 2 回あります (これは何ですか?)。クラスパスを修正すると役立ちます。

@Henning が暗示したように、ライブラリ間に競合があります。この特定のケースでは、休止状態ライブラリ (現在のタペストリー休止状態ライブラリでサポートされていないバージョン) で真のサポートを持たないタペストリー休止状態ライブラリであるため、DOCJARに移動して、真の休止状態ライブラリ(または、ライブラリでさえ、特定のタペストリー-休止状態ライブラリに必要なタップ-休止状態ライブラリの数がわからない場合があります。
