Pentaho数据集成：连接到数据库时出错：使用类org.gjt.mm.mysql.Driver

Question

我得到这个错误，但我有我的mysql-connector-java-5.1.23-bin.jar在Pentaho \ data-integration \ libext \ JDBC。看起来连接器没有加载，因为它使用了默认的连接器。我已经尝试过不同版本的jdbc，我已经检查过MD5，并且在同一个文件夹中没有其他版本的相同驱动程序。我非常渴望做这个工作，任何建议表示赞赏。

这是当我尝试写入数据库输出：

你确定那不是在服务器端有问题？你可以使用相同的证书/驱动程序连接到该数据库，并使用SquirrelSQL或其他SQL工具手动截断该表？还要确保从运行PDI的相同主机连接，也许有一些主机特定的权限/限制。
