 Post subject: How to restrict a Criteria to a subclass of a field?

Hi All,

I have the following entities:
Code:
public abstract class InformacaoFinanceira{...}

public class ContaBanco extends InformacaoFinanceira{...}

public class ContaCartao extends InformacaoFinanceira{...}

I'm using table-per-hierarchy mapping strategy.

So I have the following entity that has a relationship with InformacaoFinanceira:
Code:
public class Fatura {
...
   @OneToOne(cascade={ CascadeType.PERSIST, CascadeType.MERGE }, fetch=FetchType.LAZY)
   @JoinColumn(name="INFORMACAO_FINANCEIRA_ID")
   private InformacaoFinanceira informacaoFinanceira;
...
}


Well, what I want is create a criteria on Fatura where the informacaoFinanceira is of ContaBanco type sorting by a field of ContaBanco.

Is there a way to do this using Criteria? How?

Thanx
