org.apache.openjpa.persistence.query.QueryDefinition.addRoot()
Add a query root corresponding to the given entity, forming a cartesian product with any existing roots. The domain object that is returned is bound as a component of the given query. The argument must be an entity class. @param cls -an entity class @return DomainObject corresponding to the specified entity class.

        compare(jpql, q);
    }
    
    public void testOrderBy() {
        QueryDefinition q = qb.createQueryDefinition();
        DomainObject customer = q.addRoot(Customer.class);
        DomainObject order = customer.join("orders");
        DomainObject address = customer.join("address");
        q.where(address.get("state").equal("CA"))
        .select(order)
        .orderBy(order.get("quantity").desc(), order.get("totalcost"));
