I'm trying to create a Criteria query to select objects that are related via an association table. The following HQL works:

Code:
            String hql = "select distinct person from Person as person" +
                " join person.personLocations as personLocations" +
                " join personLocations.location as location" +
                " where nickName = 'Jim' and city like '%fran%'";
            Query q = getHibernateTemplate().createQuery(getSession(), hql);

..but when I try the following Criteria query:

Code:
            Criteria c = getHibernateTemplate().createCriteria(getSession(), Person.class)
                .add(Expression.eq("nickName", "Jim"))
                .createCriteria("personLocations")
                    .createCriteria("location")
                        .add(Expression.ilike("city", "fran", MatchMode.ANYWHERE));
            result = c.list();

..I get this error:

Code:
net.sf.hibernate.MappingException: collection was not an association: com.fweep.wombat.thelist.domain.Person.personLocations

Is it possible to form this kind of query using the Criteria API? I'd hate to have to build dynamic queries using HQL. The Criteria API is great for building dynamic queries from search forms. Hacking together HQL dynamically is pretty gross.

See mapping and exception details below.

Thanks,
Jim

Hibernate version:

Hibernate 2.1

Mapping documents:

Edited for brevity. Some irrelevent fields, and another relationship mapping (identical to personLocations, called personPhones) have been removed.

Code:
<hibernate-mapping package="com.fweep.wombat.thelist.domain">

</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():

Using Spring:

Code:
            Criteria c = getHibernateTemplate().createCriteria(getSession(), Person.class)
                .add(Expression.eq("nickName", "Jim"))
                .createCriteria("personLocations")
                    .createCriteria("location")
                        .add(Expression.ilike("city", "fran", MatchMode.ANYWHERE));
            result = c.list();
