OpenJPA is an implementation of the Java Persistence API specification.
.
It is an object-relational mapping (ORM) solution for the Java language,
which simplifies storing objects in databases.
.
OpenJPA passes the JPA 2.0 TCK, while remaining backwards compatible
with prior releases based on the Java Persistence API (JPA 1.0 - JSR-220).
This package is needed to package Spring Framework 3.0.
