Porting my enum type from Hibernate2 to Hibernate3

[Hussein Baghdadi]

Hi.
I'm port my own enumerated type in hibernate (a type like Rating class in Hibernat In Action) from Hibernate2 to Hibernate3.2.2
Well, I got tons of errors and a bunch of unimplemented methods.
I override these methods in this way :

    public Serializable disassemble(Object value) throws HibernateException {
        return (Serializable) value;
    }
 
    public Object assemble(Serializable cached, Object owner) throws HibernateException {
        return cached;
    }

But how to override replace( ) method (ofcourse I mean what is the required logic) ?
And more thing :
Does Hibernate3.2 support Java5 enum types ? or I still have to create my own enum types as Hibernate In Action suggests ?
