hi

if i have two table

table a {
id int primary key
content varchar
}

table b {
id int pk,
content varchar,
a_id reference a(id)
}

how can i do the mapping so that
a can a.getB
but b can not b.getA???

what should i specify in the hbm.xml file???

Try this one

<one-to-one name="person"
property-ref="address"/>
