## Welcome to the Apache OpenJPA project
  
Apache OpenJPA is a Java persistence project at [The Apache Software Foundation](http://apache.org)
 that can be used as a stand-alone [POJO](http://en.wikipedia.org/wiki/POJO)
 persistence layer or [integrated](integration.html)
 into any Java EE compliant container and many other lightweight
frameworks, such as Tomcat and Spring. 

The [3.x releases](downloads.html) targetting the [JSR-338 Java Persistence 2.2](http://jcp.org/en/jsr/detail?id=338) is the most current production ready release.
It is fully backward compatible compatible to our JPA 2.1, 2.0 and 1.0 releases.

The [2.x releases](downloads.html)
 (2.4.3 is the latest) are a production ready, compliant implementation of
the [JSR-317 Java Persistence 2.0](http://jcp.org/en/jsr/detail?id=317)
 specification, which is backwards compatible to the JPA 1.0 specification
and passes the Sun JPA 2.0 Technology Compatibility Kit.

The [1.x releases](downloads.html)
 (1.2.3 is the latest) are an
 implementation of the Java Persistence API (JPA) 1.0 part of the [JSR-220 Enterprise Java Beans 3.0](http://jcp.org/en/jsr/detail?id=220)
 specification.
 The development of this version is EOL.
