Can I use ODL and OQL in Oracle ?

Hi,

Recently I read a database book, one chapter is about ODL (Object Definition Language) and OQL (Object Query Language). I still dont really get it :

1. Can I use ODL / OQL on Oracle ? Or it can only be implemented on 'pure ODBMS' only ? (while Oracle is not ODBMS, is it?)
2. If the answer is Yes, does it mean I can access Oracle, e.g : from Java, without any O/R Mapping or JDBC layer ?

Thank you for any help,
