推荐答案
在同样的问题上浪费了半个小时，这是答案:
Wasted half an hour on this same problem, here's the answer:
从 http://dev.mysql.com/downloads/connector/j 下载连接器/
解压 JAR 文件.
编辑C:Program FilesWeka-3-6RunWeka.ini
将最后一行改为:
cp=%CLASSPATH%;c:/mysql-connector-java-5.1.16-bin.jar
您当然可以将 mysql-connector jar 保存到不同的路径，但请注意 正斜杠，不要介意在 Windows 上.
You may of course save your mysql-connector jar to a different path, but mind the forward slash, nevermind being on Windows.
