JDBC驅動程序與PostgreSQL和Pentaho的

現狀：JDBC驅動程序與PostgreSQL和Pentaho的

我使用PostgreSQL 9.1，現在我使用Pentaho的報表設計器來創建存儲在數據庫中數據倉庫的報告。這個數據庫被命名爲bd-datawarehouse。

我遇到的問題是當我嘗試從Pentaho Report Designer創建連接到bd-datawarehouse數據庫時。我已經配置了所有的設定，一切似乎是正確的，像下一張圖片：

但是當我點擊了Test按鈕，它給了我一個錯誤：

Error connecting to database [conexion-dw-reporting] : org.pentaho.di.core.exception.KettleDatabaseException: 
Error occured while trying to connect to the database 

Exception while loading class

您必須知道設置的所有字段都是正確的（數據庫名稱，端口號，主機名，用戶名和密碼）。

看到的錯誤，我認爲這個問題可能是我沒有JDBC驅動程序連接PostgreSQL數據庫，所以我找了，我已經像this question接受的答案難啊：我已經從here下載了我的postgresql 9.2的驅動程序，並將其放在...\biserver-ce\tomcat\lib\上，但問題仍然存在。

我不知道如何解決它，因爲我不太瞭解這是什麼問題。

任何幫助，將不勝感激！

的excepion'java.lang.ClassNotFoundException'清楚地表明你把jar文件到錯誤的目錄。您的屏幕截圖似乎來自Swing GUI，而您聲明您將該驅動程序放入Tomcat目錄。我懷疑Swing GUI使用Tomcat安裝中的庫。 –

大師！我把驅動程序放在錯誤的文件夾中。我只是將它移動到正確的文件夾，它解決了我的問題。請把你的評論作爲答案，我想感謝你的幫助 – carexcer

報告設計師\ LIB \ JDBC \ 或 BD-數據倉庫\ LIB \ JDBC \

您需要將相應的JDBC JAR文件上面的路徑。那麼您需要重新啓動pentaho報告工具。這可能是工作。它爲我工作。
