jPersist is an extremely powerful
object-relational database persistence API that
manages to avoid the need for configuration and
annotation; mapping is automatic (A-O/RM). It uses JDBC, and can work with any relational database and any type of connection resource. It uses information
obtained from the database to handle mapping
between the database and Java objects, so mapping
configuration is not needed, and annotation is not
needed. In fact, there is no configuration needed
at all.
