使用XPage休息服务连接到mysql时出错

Question

尝试通过xpages rest服务连接到mysql数据库时出现错误500“内部错误”。 Mysql ver 8，Domino Server 9.0.1 FP8。使用来自mysql的JDBC jar文件。任何人都可以帮我解决错误。

错误：

这是jdbc配置文件和驱动程序位置的组合。对于mysql，配置需要像下面的示例一样进行配置。感谢Henrik穿上写作轨道。

<jdbc type="simple">
    <driver>com.mysql.jdbc.Driver</driver>
    <url>jdbc:mysql://9900w7.int.natc-ht.com</url>
    <port>3306</port>
    <databaseName>weather</databaseName>
    <user>root</user>
    <password>password</password>
    <simple>
        <minPoolSize>10</minPoolSize>
        <maxPoolSize>20</maxPoolSize>
    </simple>
</jdbc>
