錯誤與mysql

Question

我想安裝ejbca使用mysql，但有問題。我不太確定有哪些錯誤或如何解決這些錯誤。錯誤是：

任何人都可以幫助我嗎？

Answer 1

我已經使用grep來獲取這些錯誤，如果日誌文件。我已經解決了這個問題。問題只是mysql連接器的位置。我已經將整個zip文件解壓縮到jboss/server/default/lib中。這創建了一個額外的文件夾，所以連接器是在〜/ lib/mysqlconnector/mysqlconnector.jar 我把.jar文件上移了一個級別，並且錯誤得到了解決。:)

這是完整的錯誤跟蹤？我懷疑你正在使用的是什麼AS錯誤的MySQL驅動程序（我假設JBoss）。
