Netbeansの/永続化APIエラー

Question

私はこのチュートリアルを、以下の午前、私が使用しているのNetBeans http://www.netbeans.org/kb/docs/java/gui-db-custom.html

私はである私は、「データベースからの新しいエンティティクラス」を作成する部分に取得6.5.1」チュートイアルの「マスター/詳細ビューのカスタマイズ」セクションを参照してください。私はタスクリストにこのエラーが出るのでコンパイルできません（実行時にランタイムエラーが発生します）... Atleast私はこれら2つが関連していると思います。私は、すべてのデータベースから新しい>エンティティクラスを行う、とチュートリアルが言うように、正確に行うことである

ノート。チュートリアルの作者はアプリケーションが「部分的に機能的」でなければならないと言っているので、「追加ダイアログボックス」の見出しで停止しました。生成されたコードを、私が何をするように指示されたものの外に編集したことはありません。

これは、NetBeansの出力コンソールによって生成された出力です：

私はNetBeansのアプリケーションが誤って設定か何かでなければならない、私は自分自身と同じ問題を持つ人を見つけることができないよう考えています

Answer 1

ネットビーンズのバグだったようですが、私は新しくインストールしましたが、今はうまくいくようです。

Answer 2

私は同じ問題がありました。 再インストール - 同じ問題。 デフォルト設定のRan Revoアンインストーラ。 が再インストールされました。 今回は、新規プロジェクトウィザードの直後に、処理できるようになるとすぐに、国番号&の商品テーブルを作成しました。 違いがあるかどうかは分かりませんが、今回はすべてうまくいっています

Answer 3

Netbeans IDEのアップデートは私にとってはうまくいっています。私は新しくインストールする必要はありませんでした。

Answer 4

更新：このエラーは、Netbeans 7.4では引き続き発生しています。
エンタープライズアプリケーションの-war（Web - ）モジュール内の注釈付きエンティティでも、 "NamedQueriesを定義できるだけ..."というエラーが発生します。
ejb-Module内の同じクラスはそうではありません。
明らかに、Entity-Classesが存在するはずです。
JSF - Pagesを生成するためにWebモジュールに移動していましたが、この問題が原因で正しく動作しなかったため、
を再起動してください。 EJBモジュールから生成することもできます。
