Holy cow, this is a great talk! I've had so many questions about JPA the last couple of days and within an hour I feel so much confident. Thank you so much for doing this talk and publishing it on youtube.
Question: at 15:20 about the @ManyToMany, this lecturer only told the problem, but what is the solution? seems no solution for avoiding from creating two linking tables was given
Hmm...he starts talking about JPA but then in his examples he talks about Hibernate. I'm not sure, whether everything he talks about applies to JPA or it's an implementation behaviour of Hibernater.
the thing showed at 6:30 is not valid atm is it? i tried it in my local machine and did not update the price. I am new to JPA and trying to find a good resource to study.. If some of those things are obsolete could someone mention them?

You cant know those things unless you go through the 500 pages documentation of Hibernate
Worth persisting (no pun intended) with watching this. Knowing about this stuff is important.
Thank you . You are good teacher and good lexture
He reminds me of Borat sometimes :D Great success!

You have to use @JoinTable

JPA uses hibernate under the hood. You could say JPA is an API layer over hibernate.
@@reallylordofnothing No, Hibernate is the most popular implementation of the JPA specs! Eclipselink is a distant second!
Sincere thanks..

I use natural key for equals and hashCode not a uuid field.
A Very Nice talk
Thank you..
