私はHibernate/JPAで動作するようにしようとしている単純なクラス階層を持っています。2つのテーブル間でHibernateエンティティを分割する
基本的に私はMovementDataがデータベースの主車両テーブルの整数IDにFKを持つ独自のテーブルにあることを望んでいます。
何か間違っていますか？どのように私は同様の何かを達成することができますか？ 私はJPA仕様に従っていると確信しています。 （アクションでEJB3が、これは動作するはずの言葉：EJB3 In Action: @SecondaryTable
ここで私が取得しています例外の一部されています
SEVERE: an assertion failure occured (this may indicate a bug in Hibernate, but is more likely due to unsafe use of the session)
org.hibernate.AssertionFailure: Table MOVEMENT_DATA not found

はここでそれは...車に関連する休止状態からのログイン情報の一部でありますそれは罰金のすべてを認識しているように...そして、それはいくつかの理由のために例外をスローに見えます。
