Is there a specific version of the MariaDB JDBC driver that works bets with 8.3? I just tried the last three (3.5.7, 3.4.2, 2.7.13.) and got the same errors: Error - either required files are missing or classname is incorrect ---

What translator settings and main class name are you specifying? ---

I just downloaded the driver and tried to update it in the gateway. I downloaded the mysql jdbc connector and it worked fine. I couldn’t get the MariaDB ones to work. I am using docker, ill try to get them mapped and see if that changes it. ---

What's your docker setup look like? Are you using an orchestrator like compose, a custom docker image, etc? Out of the box, the 8.3.3 docker image works for me, because the MariaDB driver module is installed: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/5/253896d98a8e95a1e4d796b5b00a92e120b48742.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/9/993d13b7696ff4ff3e5321f3f93fa31e6f3e5357.png) If you want to override the jar file version for whatever reason, make sure you first create an override of the driver config into `core`: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/7/8719bd5e4ae0b97a041b467573a456e7efe3c19e.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/3/9343ddd6cc6c1630a218893245174fc591493f81.png) Then you can 'Manage JAR files', upload a new jar, and remove the old one: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/6/868c3cb542253b6f099261704548f01bcd53a52d.png) ---

Sorry for the long wait before responding, I have been traveling. I am using docker compose, I didn’t realize I needed to overwrite the core for MySQL, I just uploaded the MariaDB jar file and it was still throwing errors. When I get back, I’ll try out overriding the core with the MariaDB jar and let you know how it goes. Thanks! ---

To be pedantic: You're overriding the driver configuration provided in 'system' _with_ a configuration in 'core' (when you create the override). Then you're just mutating the definition in core by providing a different JDBC driver jar. ---
