Convert string to int in Hibernate order criterion

Question

Basically, my question is the same as this one, but for Java's (JBoss) Hibernate: How can we order a column as int using hibernate criteria API?

I want to create an order restriction with a cast to int from a string column. Something like

criteria.addOrder(Order.asc("cast(id as int)"));

The exception is "Could not resolve property: cast(id as int) of [Class]". I've tried both cast( as ) and convert(,) with int and integer.

Despite the topic is old and may be the problem were solved, I'll post solution. Maybe it will be helpful in future for someone.

criteria.addOrder(new org.hibernate.criterion.Order("anystring", true) {
            @Override
            public String toSqlString(Criteria criteria, CriteriaQuery criteriaQuery) throws HibernateException {
                return "cast(id as int)";
            }
        });
