2. jboss envers (can this be used on any web server,tomcat,jetty, appengine) ?
3. any similar library like jboss envers that ease to do versioning?
JBoss Envers can be used always when you’re using Hibernate as the persistence provider. It’s actually bundled with the new Hibernate 3.5. Envers is a an excellent tool, but I has one drawback – you can version only entities that aggregate versioned entities. This means that if you want to version Entity A and it has fields of types B and C, which are also entities – B and C should be versioned by envers as well – if your entities have a tight coupling(which is bad design, but is fairly possible) you’ll have to version the whole project and there is some overhead to that.
We personally opted for a lighter custom versioning solution after we investigated Envers, but if it fits your bill – you should definitely use it. I’m not aware of other tools offering its capabilities.
