eXist-db installing MySQL connector - mysql

Question

Does anyone know the steps to correctly install the MySQL JDBC driver into eXist-db for MacOS? I’m following http://www.exist-db.org/exist/apps/wiki/HowTo/SQLDatabases/QueryingSQLDatabases, but am stuck at 1.2. Everything I try results in the error
exerr:ERROR sql:get-connection() Cannot find database driver class: com.mysql.jdbc.Driver [at line 4, column 20]
I’ve installed mysql-connector-java-8.0.22.jar into
/Applications/eXist-db.app/Contents/Java/
/Applications/eXist-db.app/Contents/lib/user/
/Applications/eXist-db.app/Contents/Resources/lib/user/
/Applications/eXist-db.app/Contents/Resources/etc/webapp/WEB-INF/lib/
And none of these locations resolved the error. I must be missing a step.

Answer 1

Are you working with eXist-db 5?
It is important to register the JDBC driver jar file in eXist-db. The jar file is placed in the $EXIST_HOME$/lib directory and the dependency on the jar file must be registered in eXist-db by adding an entry similar to the following in etc/startup.xml where the relativePath is the relative path to the jar file from the lib directory.
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.18</version>
<relativePath>jdbc/mysql-connector-java-8.0.18.jar</relativePath>
</dependency>
