Does Sun reference implementation given any Schema mapping tool.
The JDO RI is suitable for learning the JDO technology but should not be used in real applications. Althought it's a good implementation, you don't have offical support from Sun. At least, you should contact Sun for a contract support.
Instead, you should use one of the many JDO open source implementations supporting relational databases.
