kettle连接Oracle出现IO错误：Undefined Error

将Oracle的jar包拷到了kettle的lib下后报错如下，没头绪查找问题所在。后来将jar包又放到了C:\Program Files (x86)\Java\jdk1.8.0_131\jre\lib\ext目录下。成功连接oracle数据库。解决了困扰一周的问题。

 

后经过验证，jar包只需要放在JDK上述目录下就好，kettle的lib下在我这没用。

此外，我将kettle的安装目录F:\kettle\kettle\pdi-ce-8.1.0.0-365\data-integration设置为KETTLE_HOME系统环境变量，kettle竟然汉化了。不过这个并不影响连接问题。
