I can see that you are using reverse engineering to generate your model. Did you create the tables required by Hibernate Envers to store revision information?

Hibernate Envers requires a new entity RevisionLog to store general information about all revision (date, user, etc) which is stored in DB and one table per entity audited to store entity instance values for every revision.

gvNIX create this configuration for you but, as you are using Reverse Engineering tool, the hibernate.hbm2ddl.auto property should be set to none . So, required Envers tables will not be generated on DB.

A simple solution could be:

1. Create a temporal empty DB
2. Configure your project to use it
3. Set hibernate.hbm2ddl.auto to create
4. Start the application: Hibernate hbm2ddl will generate required tables
5. Stop application
6. Create all envers tables in original DB based on its definition of temporal DB
7. Restore DB and hbm2ddl settings in your project

Good luck!

PD: Don't forget exclude envers tables from Reverse Engineering configuration next time you execute it!.
