Hy, guys!!I am starting with Hibernate , and have a noobie question.I get it that if I want to use a foreign key where the column is also the primary key of the table, I use a code like this:

<id name="id" type="long" column="CONTACT" >
<generator class="foreign" >
<param name="property">Contact</param>
</generator>
</id>

<one-to-one name="Contact" class="roseindia.tutorial.hibernate.Contact" />

but How should I do it when the foreign column is not the primary key column ??for example:

<id name="id" type="long" column="ID" >
<generator class="increment" />
</id>

//here I want to declare property , and one of them is also a foreign key

<one-to-one name="Contact" class="roseindia.tutorial.hibernate.Contact" />


how I do it??Thanks for the help.

You can look at:

This is a good implementation of all features of hibernate.

Have a look in the reference docs, section 6.1.11 "One-to-one". The last bit describes what you want: many-to-one unique="true".
