java - Netbeans が Eclipselink モジュールを追加しているにもかかわらず、パッケージ javax.persistence が存在しない

Question

2 つの部分からなる質問:

最初の部分: どの JAR が必要ですか? javax.persistence-2.0.0.jar に必要なクラス、特に javax.persistence.* がありませんか?

ここに画像の説明を入力

スタックトレースは次のようになります。

質問の 2 番目の部分は、Netbeans の (潜在的に) 何が問題なのかということです。昨日まで、ここのように既存のデータベースから @Entity クラスを生成すると、IDE が必要なクラスをクラスパスに自動的に追加するように見えました。この特定のケースでは、Netbeans は JAR を追加しました。

ただし、それらはプロジェクトの外部から追加されるため、lib フォルダーはありません。残念ながら、私は build.xml に実際に飛び込んで何が起こっているのかを確認するのに十分な知識はまだありませんが、Library Manager からは次のように見えます。

thufir@dur:~$ tree netbeans-7.1.1/java/modules/ext/eclipselink/

└── org.eclipse.persistence.jpa.jpql_1.0.0.jar

以前は、欠落している JAR をダウンロードする追加の手順が必要だったという私の記憶とは一致しないようです。Netbeans の設定が間違っているか壊れている可能性がありますか?

違いは明らかに、プロジェクト13には./libフォルダーがあり、プロジェクト12は「外部」JARを使用していることです。

おそらく、Netbeansのインストールが壊れているか、設定が間違っているか、プロジェクト12へのアプローチが間違っていますか？ライブラリマネージャーなどのさまざまな機能の方がうまく機能するため、プロジェクト12と同様に、外部JARを使用してこれを実行したいと思います。
