I’m trying to make Java JPA and Hibernate work in my project and i can’t figure it out. I have spent two days on this and I can’t figure it out, so if anyone could help here is github project repo link -> https://github.com/Elnur1337/RSProjekat

All I get is this error:

I tried using different versions of hibernate and javax.persistance APIs (.jar files). I tried different persistence links in persistence.xml.
