<class name="Person" table="PERSON">
<id name="id" type="long" column="ID">
<generator class="sequence">
<param name="sequence">person_seq</param>

<one-to-one name="employee" class="Employee" cascade="true"/>
</class>
<class name="Employee" table="EMPLOYEE">
<id name="id" type="long" column="ID"/>
<property name="title"/>
</class>

===========
public class Person
{
private String name;
private Employee employee;
/* getter and setter methods */
}
============
I am hoping session.save(person) would insert a record into both PERSON and EMPLOYEE tables where PERSON.id = EMPLOYEE.id.. I think the mapping isn't quite correct..... Any help would be grateful.

Many Thanks.

i'm kind of surprised you don't get an xml parsing error on this... cascade="true" isn't valid... try changing the cascade value to all or save-update

<one-to-one name="employee" class="Employee" cascade="save-update"/>

I think your cascade setting is wrong in your one-to-one. Try cascade="all", not cascade="true"
