Google アプリ エンジン -GAE を使用してサンプル GWT アプリを作成し、エンティティを作成してサービス レイヤーに永続化し、正常に動作し、データを保存しました。
そこで、EntityManager を作成しようとすると、サービス層にウィジェットとその他のクラスを追加し始めました。
org.datanucleus.exceptions.ClassNotResolvedException非エンティティ クラス、e,ga ウィジェットの場合、Datanucleus が @Entity アノテーションを持たないクラスを強化しようとしている理由がわかりません。
dto パッケージの Bean のみを強化し、/src エントリを削除するように、ORM の下で Google Plugin Eclipse を構成しました。
それは決して機能しません。DN に、CLASSPATH を参照するすべてのクラスだけを拡張しないように指示できるようにする必要があるだけです。
どんな助けでも感謝します。
私は GAE バージョン 1.7.5 と GWT 2.5 および GXT 2.5.5 を使用しています。
