JPA を使用して、Google App Engine (GAE) で grails アプリケーションの 1 対多の一方向マッピングのテストを実行しようとしています。私が定義しようとしている 1 対多の一方向マッピングは、User クラスと Role クラスの間です。残念ながら、私は立ち往生しています。ただ興味深いのは、それをうまく機能させることができる開発者がそこにいるということです。
以下は私の開発環境です：
- Windows XP プロフェッショナル
- アプリ エンジン SDK 1.2.2
- グレイルズ 1.1.1
- 使用プラグイン: app-engine 0.8.3、gorm-jpa 0.5
ソース コードは次の場所にあります。
完全なエラー スタック トレースは次のとおりです。
