爲什麼我無法從JDBC連接池中ping數據庫？

我一直在關注this鏈接，爲glassfish服務器（位於Debian服務器機器上）設置MySql連接池。爲什麼我無法從JDBC連接池中ping數據庫？

當嘗試ping數據庫（位於CentOS的服務器上），我從GlassFish服務器以下錯誤：

Ping Connection Pool failed for MySqlTrace. Class name is wrong or classpath is not set for : com.mysql.jdbc.jdbc2.optional.MysqlDataSource Please check the server.log for more details.

我要強調，我在遠程訪問DB（從我的Windows筆記本電腦）與一個工作臺客戶端沒有任何問題，以及相同的憑據（我四重檢查！）。

我還張貼域1 /日誌/ server.log中

所以我在做什麼錯在這裏？

聽起來像是你的GlassFish服務器缺少MySQL JDBC驅動程序。將mysql_xxx.jar下載到glashfish_home/lib。

見https://dev.mysql.com/downloads/connector/j/

此博客似乎給一步步包括JDBC驅動程序https://computingat40s.wordpress.com/how-to-setup-a-jdbc-connection-in-glassfish/

這是它！非常感謝，我只在裏面有文件夾，你可以在編輯中看到。我忘了從它裏面取出.jar文件... – Vrankela
