無法從連接池中獲取/創建連接

我在glassfish 3上運行primefaces 3.1無法從連接池中獲取/創建連接

任何想法爲什麼我得到此異常？當我第一次創建數據源並運行時，它運行良好，但在某段時間後，此錯誤開始出現。

你正確地釋放你的連接解決問題？ – pcalcao 2012-02-24 12:33:39

@pcalcao我打開了一個連接，並最終關閉（connection，preparedStatement，resultSet）; \t \t}' – user75ponic 2012-02-24 12:46:52

我通過複製ojdbc14.jar到glassfish\domains\domain1\lib\ext
