问题描述

Situation: 情况：

I'm using PostgreSQL 9.1 and now I'm using Pentaho Report Designer to create reports from a data warehouse stored on a database. 我使用PostgreSQL 9.1，现在使用Pentaho Report Designer从存储在数据库中的数据仓库创建报告。 This database is named bd-datawarehouse . 该数据库名为bd-datawarehouse 。

The problem I have is when I try to create a connection from the Pentaho Report Designer to bd-datawarehouse database. 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。 I've configured all the settings and everything seems correct, like the next image: 我已经配置了所有设置，并且一切似乎都正确，如下图所示：

在此处输入图片说明

but when I click the Test button, it gives me the next error: 但是当我单击“ Test按钮时，它给了我下一个错误：

Hostname       : localhost
Port           : 5432
Database name  : bd-datawarehouse

You must know that all fields of settings are right (database name, port number, host name, user name and password). 您必须知道设置的所有字段都正确（数据库名称，端口号，主机名，用户名和密码）。

Seeing the error, I've thought that the problem could be that I haven't the jdbc driver to connect a PostgreSQL database, so I've looked for it and I've done like the accepted answer of this question said: I've downloaded the driver for my postgresql 9.2 from here and I've put it on ...\\biserver-ce\\tomcat\\lib\\ , but the problem persists. 看到错误后，我认为问题可能是我没有用于连接PostgreSQL数据库的jdbc驱动程序，所以我一直在寻找它，并且像已接受的这个问题的回答所说：从这里下载了我的postgresql 9.2的驱动程序，并将其放在...\\biserver-ce\\tomcat\\lib\\ ，但问题仍然存在。

I don't know how to solve it, because I don't understand so deeply which is the problem. 我不知道如何解决它，因为我不太了解这是问题所在。

Any help would be appreciated! 任何帮助，将不胜感激！

report-designer\\lib\\jdbc\\ or bd-datawarehouse\\lib\\jdbc\\ report-designer \\ lib \\ jdbc \\或bd-datawarehouse \\ lib \\ jdbc \\

You need to place the appropriate jdbc jar file to above path. 您需要将适当的jdbc jar文件放置在上述路径中。 then you need to restart the pentaho reporting tool. 那么您需要重新启动pentaho报告工具。 It might be work. 可能是可行的。 Its working for me. 它为我工作。

I've downloaded the last version of the PostgreSQL JDBC 4.2 Driver and input it on the lib folder of the Database connection program, it worked for me :) 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:)
