Jarファイルがデータベース（Hibernate）で動作しません

Question

私は、Hibernateを使ってアプリケーションを作成しました... Netbeansを通して実行すると、データベースとうまく動作します。しかし、私がアプリケーションをビルドすると（クリーンツールとビルドツールを使用して）、データベースでは動作しません。

これはjarとは関係がありません。むしろデータベース接続権限の問題です。

1）あなたのhibernate設定のアドレスまたはアカウントの情報は、あなたの稼働中のnetbeansコードで使用されているものと比較して、不正確または不完全です。あなたのjarファイルで同じ設定ファイルを使用していますか？ネットビーンズ？

または

2）。データベースへの接続が許可されていないマシンからjarを実行しています。たとえば、root以外の権限のあるIPアドレスからrootとして接続しているとします。使用しているマシン上でjarファイルを実行していますか？ネットビーンズ？
