Guice Persist provides abstractions for working with datastores and persistence providers in your Guice applications. It works in a normal Java desktop or server application, inside a plain Servlet environment, or even a Java EE container.

Guice Persist supports a simple approach to transactions and various unit-of-work semantics; both with the same declarative, annotation-based API. Switching between unit-of-work strategies is as simple as changing a configuration option.

It also follows the Guice idioms of using simple, expressive configuration and tries to remain type-safe as far as possible.
