| Overview |
| |
| These notes describe the difference between OpenJPA release 1.2.2 and the |
| preceding release: 1.2.1. |
| |
| 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. |
