【中文标题】Pentaho Spoon 由于缺少驱动程序（jar 文件）而无法连接到 IBM DB2 数据库

【英文标题】：Pentaho Spoon unable to connect to IBM DB2 database due to a missing'driver (jar file)

【问题描述】：

我正在使用 Pentaho 的勺子。当我尝试连接到 IBM DB2 数据库时，出现以下错误

`找不到驱动程序类“com.ibm.db2.jcc.DB2Driver”，请确保安装了“IBM DB2”驱动程序（jar 文件）。 com.ibm.db2.jcc.DB2Driver

我在谷歌上搜索但找不到任何东西。

【参考方案1】：

IBM 数据服务器驱动程序可以从相关的support page 或overall download page 下载。可以通过 Google 或 DB2 Knowledge Center 找到这些链接。

【参考方案2】：

我今天遇到了同样的问题。 虽然错误消息说明了需要做什么：

Driver class 'com.ibm.db2.jcc.DB2Driver' could not be found, make sure the 'IBM DB2' driver (jar file) is installed. com.ibm.db2.jcc.DB2Driver

仍然需要更多信息来解决此问题。

从 Pentaho 的 JDBC drivers reference. 获取确切的驱动程序 一旦你下载它;把合适的.jars放到Pentaho工具的lib目录下。就我而言，我在 Windows 上使用 Spoon

所以位置是：

C:\PathToWhereSpoonIsRunningFrom\pdi-ce-8.2.0.0-342\data-integration\lib

文件将是：

db2jcc.jar db2jcc4.jar db2jcc_license_cu.jar
