Hibernate manytoone not updating

In order to setup logging properly you will need JPA entities are plain POJOs. Their mappings are defined through JDK 5.0 annotations instead of files.

If you use Hibernate Core and its native APIs read on.

A good an complete set of working examples can be found in the Hibernate Annotations test suite itself: most of the unit tests have been designed to represent a concrete example and be a source of inspiration for you.

You can get the test suite sources in the distribution.

Hibernate Annotations support out of the box enum type mapping either into a ordinal column (saving the enum ordinal) or a string based column (saving the enum string representation): the persistence representation, defaulted to ordinal, can be overridden through the property example.

In plain Java APIs, the temporal precision of time is not defined.
