so I generated a Luminus app using +war and +mysql; I was able to get it to connect to the database correctly locally. However, when I deploy it up to Elastic Beanstalk as the uberwar, I get the following issue where the correct JDBC driver can't be resolved:

Caused by: java.lang.RuntimeException: Failed to get driver instance for jdbcUrl=jdbc:mysql://<my-db-url>

@pc123 typically the app server should provide the jdbc driver, but you could also add it as a dependency

I'm not too familiar with elastic beanstalk environment myself though

@pc123 I would check if jdbc driver's jar is packaged in final war file. If not, you can try to add the desired dependency to project.clj
