GlassFish 3.1.1を使用しています。およびNetBeans 6.9.1。 NetBeansでWebアプリケーションを作成し、エンティティクラスを生成しました。私が追加したのは@GeneratedValueアノテーションだけです。コードは次のとおりです。未知のBeanエンティティクラス - GlassfishとNetBeansのエラー

私のアプリケーションは、私はNetBeansの持続性ユニットによって生成された編集した、今私はこのようなSTHを持って、二つのデータベースと連携する必要があるので：

すべてがまで大丈夫です私はJSFで、このメソッドを使用しようとすると、今が、ビーン管理：

cfg.setBackuppath("foo");
CdrConfigJpaController cjc = new CdrConfigJpaController();
cjc.create(cfg);
Record rec = new Record();
RecordJpaController rjc = new RecordJpaController();
rjc.create(rec);
RecordColumn col = new RecordColumn();
col.setColumnname("foo1");
col.setRecord(rec);
RecordColumnJpaController rcjc = new RecordColumnJpaController();
rcjc.create(col);
} catch (Exception ex) {
Logger.getLogger(FileWorkerBackup.class.getName()).log(Level.SEVERE, null, ex);
}
}
私はエラーを取得以下：

私が知っているところでは、永続ユニットエディタで「モジュール内のすべてのエンティティクラスをインクルードする」にチェックを入れておくと便利なことがありますが、テーブル間のクロスdb参照に関するエラーが表示されます私はこれをやろうとしていない）。 私はまた、グラスフィッシュの再起動が（閉じられていない持続セッションのために）助けになることをGoogleでも発見しましたが、それは役に立ちません。 私に正しい方向を教えてください。
おかげで交尾する必要があります！ Dunnoはどこから間違ったパッケージ名を出したのですか？ありがとうございます。 – greenskin
