Default column values with Annotations?

Is there some way to set the default column value for columns with Annotations? I see there is a way with both the Property tag and Column tag in XML configuration, but I see nothing like that with Annotations. What am I missing?

Hibernate version:
hibernate-3.2.0.CR2 hibernate-annotations-3.2.0.CR1

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

It can be done using a callback method:

Code:

@Entity
@EntityListeners({YourListener})
public class YourEntity {
    private String someProperty;
    // you know the rest
}

public class YourListener {
    @PrePersist
    public void prePersist(YourEntity e) {
        if (e.getSomeProperty() == null)
            e.setSomeProperty("some value");
    }
}

You can also annotate a method in the entity as @PrePersist and not create a listener.
