To assist in developing persistence applications OpenJPA works out-of-the-box with popular IDE's such as Eclipse and Netbeans. Additionally, plugin modules are available for the Apache Maven software project management and comprehension tool.The OpenJPA website also notes:
Many projects have adopted OpenJPA to provide the Object Relational Mapping for their needs, including Apache ActiveMQ, BEA Kodo, BEA WebLogic Server, Apache Camel, Apache Geronimo, Apache Ode, Apache OpenEJB, and IBM WebSphere Application Server. The community plans shortly to release version 1.0.0 of OpenJPA, reflecting the maturity and production quality of the code base.
Additionally, OpenJPA has been integrated with numerous other frameworks including Spring Framework, GlassFish, JOnAS Application Server, Sun Java System Application Server.
BEA Kodo: Kodo is the project from which the OpenJPA source code was derived. Kodo is now, in turn, based on the Apache OpenJPA project and is in production use in hundreds of mission-critical applications around the world. OpenJPA is included as part of Kodo 4.1 and higherOpenJPA recently graduated from the Apache Incubator to become a top-level project. The project's implementation of JSR-220 (Java Persistence API) also recently passed the JCP TCK at 100%, indicating full compliance with the standard.
WebSphere Application Server Version 6.1 Feature Pack for EJB 3 Alpha: The Alpha release of the IBM WebSphere Application Server Feature Pack for EJB 3.0 contains a preliminary implementation of the Enterprise JavaBeans Version 3.0 specification, commonly known as EJB3. Associated with the Enterprise JavaBeans Version 3.0 specification is the Java Persistence API specification, commonly known as JPA. The Alpha JPA implementation is powered by OpenJPA.
InfoQ last May reported on OpenJPA possibly becoming a viable competitor to Hibernate, it seems that the liberal Apache license and quality Kodo implementation is allowing the project to get significant adoption from most of the other players in the community, both commercial and open source. One notable exception is Sun's Glassfish server (the Java EE RI), which bundles Toplink Essentials from Oracle. Oracle announced in March that it will be contributing all of the commercial Toplink to the Eclipse foundation as part of the Eclipselink project, the first releases set to be available sometime in July.

How's the Spring support for additional functionality coming?

In that other thread linked from May 2006, Rod Johnson talked about implementing added functionality such as QBE or Criteria on top of JPA in a vendor-neutral way... How's that coming? I'm sticking with Hibernate APIs until Filters and Criteria are available elsewhere.
Congratulations!

Congratulations to Marc P. and Patrick L. :-)
I hope to soon drop Hibernate and replace it with OpenJPA for my Tudu Lists project. It will be interesting to see if there is any performance boost, and at least it will solve some ASM version incompatibility between Hibernate 3 and Spring 2...

I have no doubt that OpenJPA ist a great piece of software. I am using it for years :) Of course not directly but in the way of using Kodo. I am also thinking about using OpenJPA instead of Kodo, but due to the fact that i am still use the JDO interface of Kodo, i cant change that easily. So perhaps i will stick with BEA Kodo 4.x which is essentially OpenJPA + JDO.
I wonder if Abe White is still on board...
