JDBC驱动程序与PostgreSQL和Pentaho的

现状：JDBC驱动程序与PostgreSQL和Pentaho的

我使用PostgreSQL 9.1，现在我使用Pentaho的报表设计器来创建存储在数据库中数据仓库的报告。这个数据库被命名为bd-datawarehouse。

我遇到的问题是当我尝试从Pentaho Report Designer创建连接到bd-datawarehouse数据库时。我已经配置了所有的设定，一切似乎是正确的，像下一张图片：

但是当我点击了Test按钮，它给了我一个错误：

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

您必须知道设置的所有字段都是正确的（数据库名称，端口号，主机名，用户名和密码）。

看到的错误，我认为这个问题可能是我没有JDBC驱动程序连接PostgreSQL数据库，所以我找了，我已经像this question接受的答案难啊：我已经从here下载了我的postgresql 9.2的驱动程序，并将其放在...\biserver-ce\tomcat\lib\上，但问题仍然存在。

我不知道如何解决它，因为我不太了解这是什么问题。

任何帮助，将不胜感激！

的excepion'java.lang.ClassNotFoundException'清楚地表明你把jar文件到错误的目录。您的屏幕截图似乎来自Swing GUI，而您声明您将该驱动程序放入Tomcat目录。我怀疑Swing GUI使用Tomcat安装中的库。 –

大师！我把驱动程序放在错误的文件夹中。我只是将它移动到正确的文件夹，它解决了我的问题。请把你的评论作为答案，我想感谢你的帮助 – carexcer

报告设计师\ LIB \ JDBC \ 或 BD-数据仓库\ LIB \ JDBC \

您需要将相应的JDBC JAR文件上面的路径。那么您需要重新启动pentaho报告工具。这可能是工作。它为我工作。
