| <h2><a name="Overview"></a>Overview</h2> |
| |
| <p> These notes describe the difference between OpenJPA release 1.2.2 |
| and the preceding release: 1.2.1. |
| <P> |
| OpenJPA is a feature-rich implementation of the persistence part of |
| Java Community Process 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. |
| This release of OpenJPA is 100% compliant with the JPA specification. |
| </p> |
