1.5.2. About Auditing Persistent Classes

Auditing of persistent classes is done in the JBoss Enterprise Web Server through Hibernate Envers and the @Audited annotation. When the annotation is applied to a class, a table is created, which stores the revision history of the entity.

Each time a change is made to the class, an entry is added to the audit table. The entry contains the changes to the class, and is given a revision number. This means that changes can be rolled back, or previous revisions can be viewed.
