JPAと統合しようとするGoogle App Engineアプリ（GAE/J）の実行に問題がありますが、私はGoogleの公式チュートリアル（http://code.google.com/appengine/docs/java/datastore/jpa/overview.html）の簡単な手順に従った。私は適切な場所にpersistence.xmlファイルを設定し、SDKからJARをダウンロードし、Eclipse SDKを使用して外部JARとしてプロジェクトに追加しました。私は現在Mavenを使用していないので、手動でやっています。Google App Engine（GAE/J）アプリをJPA（DataNucleus）に統合できません
私は、次の警告、エラーと例外が私のコンソール上に表示されGAEアプリケーションを実行すると：私は動作しません持って、このアプリが起動した後

Thanx！
混乱していることは、最初に想定される自動拡張が、クラスPersonが拡張されていることを私に伝えます。 EclipseのDataNucleusプラグインからDataNucleus Enhacerの出力を表示します。 DataNucleus Enhancerは1クラスで成功しました。タイミング：入力= 266ms、エンハンス= 153ms、合計= 419ms。詳細はログを参照してください –
DN eclipseプラグイン（実際に使用している場合で、拡張機能を備えたGAE Eclipseプラグインではありません）には、自動拡張ではなくリクエスト時に拡張するオプションがあります。それがあなたのクラスが実際に強化されることを保証する方法です。 GAE Eclipseプラグインには、毎回のコンパイル後に強化されないという問題がありました – DataNucleus
私はリクエストによって「強化」を行っています。同じことが起こった... –
