Hibernate version:
3.1 beta3
hibernate-tools 3.1 CVS version

Is it possible to map inheritance with tools.
(in my case InheritanceType.JOINED)
I am looking for something like

Code:

@Entity()
@Inheritance(strategy=InheritanceType.JOINED )
public class Boat implements Serializable { ... }

@Entity()
public class Ferry extends Boat { ... }

With build.xml having

Code:

How to generate

Code:

@Entity()
public class Trainer {
    @OneToMany
    @JoinTable(
            table=@Table(name="TrainedMonkeys"),
            joinColumns = { @JoinColumn( name="trainer_id") },
            inverseJoinColumns = @JoinColumn( name="monkey_id")
    )

    public Set<Monkey> getTrainedMonkeys() {
    ...
}

@Entity
public class Monkey {
    ... //no bidir
}

What do you mean "support inheritance" ?

If you mean from reverse engineering then no since we dont have enough information from a jdbc schema to deduce inheritance.

Yes I mean for reverse engineering.
I thought that it can be defined in hibernate.reveng.xml file or something like join.xml.

And for many-to-many association, the association tables could be declared in hibernate.manytomany.xml so hibernateTools could know what shoud be maded.

neither is possible and if they were going to be specified it should be reveng.xml which controls JDBCBinder/JDBCReader's interpretatin of the jdbc model into ORM model

How about adding something like "Vehicle:Car;Vehicle:Truck;Vehicle:Tank;Vehicle:Car:SportsCar" and the tool can deduce the tables Vehicle, Car, Truck, SportsCar, and Tank should be in a inheritance hierarchy. Then a switch to determine the type of inheritance mapping type.

might be ok - not a priority though....
