Overview

The Apache OpenJPA community is proud to release a 2.0.0 distribution of OpenJPA. This distribution is based on the final JSR 317 Java Persistence API, Version 2.0 specification and passes the JPA 2.0 TCK, while remaining backwards compatiable with prior releases based on the Java Persistence API (JPA 1.0) part of Java Community Process JSR-220 (Enterprise JavaBeans 3.0). Included in this release are many enhancements, fixes, and new functionality; giving developers access to all the new features of JPA 2.0, including:

• Access Types - expanded to allow specification on a per-persistent type basis or on individual attributes.
• Embeddables - expanded to include collections of embeddables, nested embeddables, and embeddables containing relationships to other entities.
• Enhanced Map Collections - expanded to support ElementCollection and new annotations for MapKeyColumn, MapKeyClass and MapKeyJoinColumn
• Derived Identities - enables the ID of an entity to be derived from another entity, which provides for parent-to-dependent relationships
• Query API - methods to get typed query parameters and results, supported and in-effect hints and lock mode getter/setter
• Locking - official support for Pessimistic locking (included in prior OpenJPA releases) along with LockModeType properties and hint
• JPQL Updates -
  • Embeddables support for path expressions to nested Embeddables and Embeddables with relationships
  • Enhanced Map Collection support for ElementCollection and new query expressions for KEY, ENTRY, VALUE
  • Support for CASE and TYPE expressions along with IN expressions for Collection parameters
  • Support for native date/time/timestamp literals
  • Support for INDEX expressions on an OrderColumn
• L2 Cache -
  • Provides cache operations such as entity eviction and cache mode behaviors to use, bypass or refresh items
  • Per-entity annotation to specify whether an entity should be cached
• Bean Validation - supports using a JSR 303 implementation for entity validation for persist and remove operations
• Metamodel API -
  • Provides API to dynamically retrieve metamodel information for a persistence unit
  • Used with Criteria API to generate and execute type safe queries
  • Supports dynamic or static generation of the metamodel
• Criteria API -
  • Provides programmatic construction of queries using an object based query graph
  • Operates on Metamodel objects to provide compile-time type safety enforcement
• EntityManagerFactory API - updated for new L2 Cache, Properties, Criteria and Metamodel APIs
• EntityManager API - updated for new Query and Query Result APIs, Hints, Properties, LockModeType, and Detach
• OSGi - support for the Persistence Unit Service Specification 1.0 in the OSGi Service Platform Release 4 Enterprise Version 4.2 specifications has been provided by integration with the Apache Aries JPA module
• And many more...

This distribution is based upon the contributions provided in all of the development iterations for 2.0, as defined in the JPA 2.0 Roadmap at: http://openjpa.apache.org/jpa-20-roadmap.html

Additional information on the OpenJPA project may be found at the project web site: http://openjpa.apache.org

Prerequisites

In normal usage, OpenJPA requires Java 5 or higher and a relational database of some sort. The metamodel generation and annotation processing features require Java SE 6 or higher.

Documentation

If you have questions about OpenJPA, a good source of information is the online product manual. You can find the manual for the current release as well as older releases of OpenJPA at http://openjpa.apache.org/documentation.html

If you can't find what you're looking for in the manual or would like more clarification you please post to the OpenJPA development mailing list. Information on all of the OpenJPA mailing lists may be found here: http://openjpa.apache.org/mailing-lists.html

Getting Involved

The Apache OpenJPA project is being built by the open source community for the open source community - we welcome your input and contributions!

What we are looking for:

• Source code and fixes contributions
• Documentation assistance
• Product and feature suggestions
