動作 Webコンテナを再起動するたびに、すべての処理が2〜3分かかり、このエラーがスローされます。私は何が欠けていますか？
EDIT：
は、今私は、同様のアプリケーションスコープのエンティティを使用し、同じエラーが国のエンティティのために発生します。ユーザーと国の両方が、persistance.xmlのクラスとして定義されています。さらに、exclude-unlisted-classesはfalseに設定されます。

今、このエンティティは、アプリケーションスコープで使用されているとエンティティは、このエラーをスローGlassfishのが完全に起動に失敗していること。
第2版： 現在の動作に基づいて、最初のホットデプロイメントまでWebコンテナが起動して正常に動作しているようです。
Netbeansを使用していると思いますか？おそらく関連しています：http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/metamodel_api#DI_101:_20100218:_Descriptor.javaClass_is_null_on_a_container_EM_for_a_specific_case – BalusC
Eclipse Indigo Service Release 1を使用していますが、それは私が得る正確なエラーです。 – TGM
わかりません。 JTAに取引タイプを設定しようとしましたか？これはJava EE Webアプリケーションの中でも最も賢明な選択です（そうしないと、トランザクションを開始、コミット、ロールバックするために、たくさんのボイラープレートコードを手動で作成/コピーしてしまいました）。最後のスタックトレースは、 'static'イニシャライザブロック内でJPAジョブをやっていることを伝えます。理論的にはうまくいくはずですが、これはEE環境では悪い考えです。代わりにアプリケーションスコープBeanの（ポスト）コンストラクタで行います。 – BalusC
