Some of the key features included in this distribution: * TBD... This early access distribution is based upon the contributions provided in development iterations 8 through [TBD], as defined in the JPA 2.0 Roadmap at: http://openjpa.apache.org/jpa-20-roadmap.html The JPA 2.0 Roadmap contains a complete list of implemented features and feature summaries, including what is on deck for future iterations.

Notices ------- Copyright 2006-2009 Apache Software Foundation This product includes software developed at The Apache Software Foundation (http://www.apache.org/). This is an implementation of an early-draft specification developed under the Java Community Process (JCP) and is made available for testing and evaluation purposes only. The code is not compatible with any specification of the JCP. The complete list of notices can be found in NOTICE.txt included in each assembly. Prerequisites ------------- In normal usage, OpenJPA requires Java 5 or higher and a relational database of some sort. 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!
