When I run the application (Hibernate, JPA) in IntelliJ IDEA, everything works without errors, but the jar file created by Maven when launched on the server gives an error:
java.lang.NoClassDefFoundError: jakarta/persistence/Persistence
I don't know much about running the application on the server, please tell me what I'm missing. Dependencies have been added, the configuration seems to be all there too.
Here is my code:

This is my project structure:

Is there's something wrong with my project structure or what am I missing?
