After upgrading to Java 17 and Spring Boot 3.0.1, jakarta is also replacing javax. You can add as many datasources as you like, as long as they share the same username/password and driveClassName.

Spring Boot configure and use two data sources
What is the jakarta equivalent or how do we configure this?
