Prevayler is a lot simpler than that. Basically you extend this special prevayler class, and Prevayler periodically serializes all the state attached that class (e.g. a HashMap member). There's no built-in query mechanism or transaction support. The only thing it does (which is not a deficiency but rather a positve separation-of-concerns thing IMO) is guarantee that you won't lose info in a system crash due to the command pattern thing.
