reverse engineer ActiveRecord data model to jpa

are there any tools which would read a data model exposed via ActiveRecord and generate equivalent data model using JPA?开发者_开发百科

note: We don't have any experience with ruby


To my knowledge, there is no such tool and I'd suggest to generate the physical model from your active records and then to reverse engineer the physical model into JPA entities. This would work (and is IMO the simplest solution).


Yes, as pascal Thivent mentioned, you can generate a schema in the DB, then you can use a tool like Middlegen to generate your Hibernate things, and from there - a short step to JPA, since JPA is largely based on Hibernate.
