私は、Hibernate JPAで設定されたC3P0接続プールで、persistence.xmlで奇妙なケースがあります。C3P0プールが間違ったMySQLサーバに接続する
これは私のpersistence.xmlです：アプリのJARパッケージを構築した後

私はローカルマシン上で実行した場合、それは動作しますが、それはAAA.BBB.CCC.DDDでMySQLサーバに接続することができます。
私は、リモートサーバー上のJARアプリを実行する場合は、私はエラーを取得：

私はAAA.BBB.CCC.DDDでサーバーを構成しますがC3P0データソースは、MySQLサーバに接続しようとしている奇妙なことリモートホストではAAA.BBB.CCC.EEEです。
私はlocalhostまたはAAA.BBB.CCC.EEEでコード内の任意の場所を設定しません。
これを経験したことがありますか？
