Hi,

Hibernate version: 3.2

Name and version of the database you are using: Postgres 8.1.4

reading doc I'm quite confused. I'm newbie to hibernate and I don't know exactly if and how is it possible customize id-sequence in a table. My own case is:

my id-sequence: 1byte-7bytes and so for example:
1-0...1
1-0...2
....
2-0...1
etc

this id-sequence must be safe-thread.

Is it possible customize a id-sequence with hibernate? is there doc about it?

Thanks,

Hibernate enables you to write an own key generator and use it. Check out http://www.hibernate.org/hib_docs/v3/api/org/hibernate/id/IdentifierGenerator.html

Ok, thanks.

I suppose I need to a kind of this:

public class MyGenerator implements IdentifierGenerator {

private IdentifierGenerator myid = ...;

public Serializable generate(SessionImplementor session, Object object)
throws HibernateException {

.....
return new Bytes( ( new Long(myid).toString()).getBytes() );
}

}

<id name="id" type="long" unsaved-value="null">
<generator class="MyGenerator"/>
</id>

Is it correct?
Is it automatically safe-thread????

Thanks,
Rand
