與MySQL無法從Glassfish的
連接到JDBC連接池我正在運行的GlassFish Server開源版3.1.2.2（建5）我創建使用NetBeans JDBC連接池。
使用Google搜索這個問題我發現添加它是一個類路徑問題。 Connecting a MySQL database to Glassfish classpath is not set or classname is wrong 和 在目錄中添加了jar。
C:\Program Files\glassfish-3.1.2.2\glassfish\domains\domain1\lib
，並試圖在
C:\Program Files\glassfish-3.1.2.2\glassfish\domains\domain1\lib\ext
服務器重新啓動多次。重新創建連接池，但沒有成功。
我得到這個當我嘗試從管理控制檯ping來
Error An error has occurred
Ping Connection Pool failed for AffableBeanPool. Class name is wrong or classpath is not set for : com.mysql.jdbc.jdbc2.optional.MysqlDataSource Please check the server.log for more details.

'仍然沒有成功。「 - 你究竟在做什麼？你有沒有收到任何錯誤信息？ –
'請查看server.log瞭解更多詳情！什麼是server.log文件說的？我正在使用'com.mysql.jdbc.jdbc2.optional.MysqlXADataSource'的MySQL池，沒有任何問題。乾杯 – SimonSez
@Andreas請看看。增加了錯誤信息。 – karx
