带有PostgreSQL和Pentaho的JDBC驱动程序

Question

情况：

我正在使用PostgreSQL 9.1，现在我正在使用Pentaho Report Designer从存储在数据库中的数据仓库创建报告。此数据库名为bd-datawarehouse。

我遇到的问题是当我尝试创建从Pentaho Report Designer到bd-datawarehouse数据库的连接时。我已经配置了所有设置，一切似乎都正确，如下一张图片：

但是当我点击Test按钮时，它会显示下一个错误：

Error connecting to database [conexion-dw-reporting] : org.pentaho.di.core.exception.KettleDatabaseException:

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

看到错误，我认为问题可能是我没有连接PostgreSQL数据库的jdbc驱动程序，所以我已经找到它并且我已经完成了{{3的接受答案}说：我已经从this question下载了postgresql 9.2的驱动程序，我把它放在...\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！

Answer 1

报告设计者\ lib中\ JDBC \ 要么 BD-数据仓库\ lib中\ JDBC \

您需要将相应的jdbc jar文件放在上面的路径中。那么你需要重新启动pentaho报告工具。它可能是有用的。它为我工作。

Answer 2

我已经下载了最新版本的PostgreSQL JDBC 4.2驱动程序，并将其输入到数据库连接程序的lib文件夹中，它对我有用：）
