Hi.
I want to know how can I figure out the ID generated by the database after session.save() method.
I have a class that contains several fields, and I want the ID field to be populated after perssisting the object.
Is there a natural way for that to be done ?

I'm not really sure what you are asking, but hibernate id-field could perhaps be used. If you map the property as

<id name="id" column="id">
<generator class="native"/>
</id>

then hibernate will populate this column with a fresh id upon persisting the object. The id can be found using the getter from the persistence class.
