These ...The goal of Autofetch is reduce the modularity penalty and programmer burden of specifying associations which should be loaded with an object query. These specifications are sometimes are called fetch profiles, prefetch directives, or joins. These specifications are an important performance optimization because they reduce the number of round-trips to a persistence store whether that be a relational database, object database, or flat file. Autofetch is a library which integrates with object persistence tools and automatically handles prefetching data. Using dynamic program profiling, Autofetch determines the right prefetch directives for each query a program executes.

Ebean is a Object Relational Mapping Persistence Layer written in Java (Open Source LGPL license).
* Providing the features of EJB3's JPA (and more)
* No container required
* JPA compatible ORM mapping (@Entity, @OneToMany, ...)
Why use Ebean?
Ebean provides a simpler approach to Object Relational Mapping. It does this by not requiring session objects such as JPA EntityManager, JDO PersistenceManager, Hibernate Session, Toplink ClientSession.

In this article, system architect Per Mellqvist presents a generic DAO implementation class based on Hibernate. He then shows you how to use Spring AOP introductions to add a typesafe interface to the class for query execution."

Persist and retrieve POJO and Map objects directly. Designed for developer productivity. Simpler, easy to learn, easy to configure as compared to Hibernate, JPA, etc.
jLynx generates JavaBean objects based on your database schema. For example if you have 24 tables and views in your database, jLynx will create 24 objects with properties that map to the field names in each table. The jLynx Generator creates the objects and compiles them. You can also use the generated source instead if you prefer to customize the objects. Using the API to persist objects is trivial.
jLynx Framework implements the Relational interface, which has all necessary methods to persist objects and fetch entire collections of objects.
jLynx leverages the strengths of SQL and the strengths of Java without having to write/maintain J2EE code. It is truly the best of both worlds.

XStream is a simple library to serialize objects to XML and back again.
Features
* Ease of use. A high level facade is supplied that simplifies common use cases.
* No mappings required. Most objects can be serialized without need for specifying mappings.
* Performance. Speed and low memory footprint are a crucial part of the design, making it suitable for large object graphs or systems with high message throughput.
* Clean XML. No information is duplicated that can be obtained via reflection. This results in XML that is easier to read for humans and more compact than native Java serialization.
* Requires no modifications to objects. Serializes internal fields, including private and final. Supports non-public and inner classes. Classes are not required to have default constructor.
* Full object graph support. Duplicate references encountered in the object-model will be maintained. Supports circular references.
* Integrates with other XML APIs. By implementing an interface, XStream can serialize directly to/from any tree structure (not just XML).
* Customizable conversion strategies. Strategies can be registered allowing customization of how particular types are represented as XML.
* Error messages. When an exception occurs due to malformed XML, detailed diagnostics are provided to help isolate and fix the problem.
* Alternative output format. The modular design allows other output formats. XStream ships currently with JSON support and morphing.

It supports persistence to all of the major RDBMS on the market today, persistence to the DB4O object datastore, supporting all of the main Object-Relational Mapping (ORM) patterns demanded by today's applications, allows querying using either JDOQL, SQL, or JPQL, and comes with its own byte-code enhancer. JPOX is available under the Open Source Apache 2 license, allowing access to not just a top quality Java persistence implementation but also to the source code, allowing you to contribute to the success story of the principal standards-compliant Open Source persistence implementation in the world today.
