jar file for persistence library
I'm currently learning to work with Hibernate. In an example I need to do the import of persistence.*;
When I'm doing this import there occurs an error like: "The import persistence cannot be resolved". I think I have to add a jar-file that contains the persistence library. But I don't have a clou witch library I have to add.
Does anyone here know how I can resolve this problem. Oh, I'm working with Eclipse as IDE.
Thank you in advance
