[CONF] Apache Cayenne Documentation: JPA Introduction (page edited)

[confluence]

Page Edited : CAYDOC : JPA Introduction JPA Introduction has been edited by Ari Maniatis (May 11, 2009). Change summary: reflect JPA direction of Cayenne (View changes) Content: Apache Cayenne JPA Some parts of the Java Persistence API (JPA) specification (JSR-220), also known as EJB3, have been implemented in Cayenne. However a full implementation is not available and therefore Cayenne cannot be said to comply with JSR-220. Some more useful parts of the specification are available, such as lifecycle events and EJBQL. These will make the job of porting an application from a JSR-220 compliant ORM to Cayenne somewhat simpler, but it is not a matter of replacing your old jar with Cayenne and having everything just work. The Cayenne API is a powerful and intuitive way of interacting with your data, and in the developers' opinion a more flexible and powerful approach than sticking to a pure JSR-220 interface. There is no short term plan to complete the JPA integration of Cayenne.
