Hibernate version: 2.1.3
Mapping document
Code:
<hibernate-mapping package="gr.forthnet.openseas.models">
<class name="Port" table="ports">
<id name="abbreviation" column="port_id" type="java.lang.String" unsaved-value="null" length="32">
<generator class="hilo"/>
</id>
<property name="name" column="port_name" not-null="true" />
<bag name="destinations" table="fromto" cascade="all" inverse="true" lazy="false">
<key column="originID"/>
<many-to-many column="destinationID" class="Port" />
</bag>
</class>
</hibernate-mapping>
Code:
