Hello,
in Company class if I used @hibernate.set table="globalmkt_contact" lazy="true" and I got: Failed to lazily initialize a collection - session is disconnected.
and if I set lazy="false" I got "Illegal attempt to associate a collection with two open sessions" Exception.
Hibernate version:2.1.7

Mapping documents:
------------Company.hbm.xml--------------------------------------------
<hibernate-mapping>
<class
name="com.leoni.globalmarketdb.model.Company"
table="globalmkt_Company"
dynamic-update="false"
dynamic-insert="false"
>
<id
name="id"
column="company_id"
type="java.lang.Long"
>
<generator class="identity">
</generator>
</id>
<set
name="contacts"
table="globalmkt_contact"
lazy="true"
inverse="false"
cascade="all"
sort="unsorted"
>
<key
column="company_id"
/>
<one-to-many
class="com.leoni.globalmarketdb.model.Contact"
/>
</set>
</class>

</hibernate-mapping>

---------Contact.hbm.xml-----------------------------------------------------
<hibernate-mapping>
<class
name="com.leoni.globalmarketdb.model.Contact"
table="globalmkt_Contact"
dynamic-update="false"
dynamic-insert="false"
>
<id
name="id"
column="contact_id"
type="java.lang.Long"
>
<generator class="identity">
</generator>
</id>
<many-to-one
name="company"
class="com.leoni.globalmarketdb.model.Company"
cascade="none"
outer-join="auto"
update="true"
insert="true"
column="company_id"
/>
<property
name="contactName"
type="java.lang.String"
update="true"
insert="true"
column="contactName"
length="128"
/>
</class>

</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():
Transaction tx = session.beginTransaction();
Set contacts = company.getContacts();
contacts.add(contact);
company.setContacts(contacts);
session.update(company);
tx.commit();
I have also used company.getContacts().add(contact); and I got the same exception

If the above is correct, then contact is created/retrieved outside of the session that you are beginning. You have to synchronise the contact with the current session before using it with objects loaded in this session, e.g. with session.lock() or session.merge().
