| ==== Persistence (JPA) |
| |
| Apache Karaf provides JPA persistence providers (such as Apache OpenJPA) to be easy to use (in a OSGi way) and provide |
| container managed persistence for applications (using Blueprint). |
| |
| Apache Karaf embeds Aries JPA, providing a very easy way to develop applications that use JPA persistence. |
| |
| See the developer guide for details about developing applications that use JPA. |
