Pentaho錯誤 - ConnectionServiceImpl.ERROR_0009 - 連接數據庫[空]失敗

Question

我試圖建立與MySQL服務器（本地主機）pentaho連接。但是，此錯誤「ConnectionServiceImpl.ERROR_0009 - 連接數據庫[空]失敗」當我嘗試測試連接時出現。有關服務器的信息應該是正確的。 資料圖片：

[我在MySQL的root帳號沒有密碼]在Pentaho服務器lib文件夾已經insered和MySQL連接器文件。

連接器文件夾圖片：

我看了日誌文件，我發現這對我的連接測試：

我已經看了許多解決方案，但我還沒有找到任何東西。它缺少什麼？

Answer 1

這裏有幾件事情：

• 是您的MySQL服務器上運行localhost？它是否在端口3306上運行？
• 您確定這是您顯示的正確連接嗎？在日誌中說Cannot initialize org.gjt.mm.mysql.Driver（舊版本），但在連接窗口中提供了com.mysql.jdbc.Driver（新版本）。爲什麼區別=
• 這看起來對我來說你使用了錯誤的驅動程序類。連接是否在別處定義？

編輯

爲 「Pentaho的驅動程序jar目錄」 第一個結果是this page。它指出，外部罐必須進入該目錄

pentaho/jdbc-distribution 

之後一個文件被執行

distribute-files.bat <name of JDBC driver JAR> 

然後重新啓動服務器。此外，還有一個您使用的應用程序的文件夾列表。
