As I have mentioned before, I beginning to do some work with JPA. As such, I am watching a few videos to help expand upon what I have read.
This video covers exactly what it says in the title. While I do not see a way around it, a lot of these videos spend a good amount of time setting up the project. This video is no exception. The meet of the subject comes in the last third where you see how to create a join query and return object.
