Yes. JPA is just a specification. You still need a persistence provider (implementation) like hibernate. If you use hibernate as your persistence provider you can still set the hibernate property (hibernate.hbm2ddl.auto) to have it generate your ddl.

From what I recall ... (I usually do it the other way from DB -> Classes)


In Eclipse J2EE, start a new JPA project.

Import your annotated Java POJOs (Well I guess they're not plain anymore ;))

Click with right mouse button, and it should give you the option to generate DB object from Classes.

You may have to do some DB configuration, connection properties etc..
