Hibernate 2.1.1 compatibility with Oracle 12c

Hi
But I do not find answer. I am migrating from Oracle 9i to Oracle 12c.

Hibernate 2.1.1 does not support Oracle 12c, but connection is normally done.
Can I use the same dialect available with hibernate 2.2.1 org.hibernate.dialect.OracleDialect .

I’m Project jdk 1.4+ojdbc14.jar+hibernate 2.1.1+oracle 9i to jdk 1.6+ojdbc16.jar+hibernate 2.1.1+oracle 12c Compatible question?

If you have a problem, please Just let me know in advance.
