Welcome to Apache OpenJPA

Welcome to Apache OpenJPA, a Java EE persistence project of the Apache Software Foundation. It aims to be a feature-rich implementation of the persistence part of Sun JSR-220 (Enterprise JavaBeans 3.0), which is known as the Java Persistence API (JPA). OpenJPA can be used as a stand-alone POJO persistence layer, or it can be integrated into any EJB3.0 compliant container and many lightweight frameworks.

Apache OpenJPA is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the DB PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
