I am using EJB3-Cartridge to generate data access layer for my application. The domain model contains the datatype money, which I want to generate as Embedded Value Object. Money datatype should have additionally some methods like add() and changeCurrency(). EJB3-Cartridge generate this classes:

Code:

public abstract class Money
    implements java.io.Serializable
{
    ...
}

Code:

public class MoneyImpl
    extends Money
{
    ...
}

The entities using the money datatype reference the abstract class money

Code:

public class Bill
    implements java.io.Serializable
{
   ...
    @javax.persistence.Embedded
    public Money getAmount()
    {
        return _amount;
    }
}

If I try to get the entity from the database the following error occurs:

javax.persistence.PersistenceException: org.hibernate.InstantiationException: Cannot instantiate abstract class or interface: Money

Is it possible to generate, like by entities, an embedded abstract class MoneyEmbedded and embeddable class Money, where the additionally methods should be implemented?
