I am using hibernate 3 annotations to annotate relationship between classes.

I have a class with name Person and below is the content

Class Person
{
Private Contact a;
Private Department b;
private String name;


@OneToOne(fetch=FetchType.LAZY, mappedBy="Person", cascade=CascadeType.ALL)
public Contact getA() {
return a;
}

@OneToOne(fetch=FetchType.LAZY, mappedBy="Person", cascade=CascadeType.ALL)
public Contact getB() {
return b;
}
}

I am using below statements to retrive person details like Contacts and Department which he belongs

DetachedCriteria searchCriteria = DetachedCriteria.forClass(Person.class)
.add(Restrictions.eq("name", "John"))
.addOrder(Order.asc("name"));
getHibernateTemplate().findByCriteria(searchCriteria);

But in this same even when i want only contact details and not Department, it is fetching data from both the table. I need to know how to add a filter or restriction in such a way only contact details are fetched and Department related details are not even queried.
