Hi,

Now am trying with many-to-many mapping. I am getting an exception

org.hibernate.MappingException: An association from the table PERSON_EVENT refers to an unmapped class: events.EVENT

Here is my 3 xml files :

<hibernate-mapping>
<class name="events.Person" table="PERSON">
<id name="id" column="PERSON_ID" >
<generator class="increment"/>
</id>
<property name="age"/>
<property name="firstName"/>
<property name="lastName"/>

<set name="events" table="PERSON_EVENT">
<key column="PERSON_ID"/>
<many-to-many column="EVENT_ID" class="events.EVENT">
</many-to-many>
</set>
</class>
</hibernate-mapping>
-------------------------------------------------------------------------------
<hibernate-mapping>
<class name="events.Event" table="EVENTS">
<id name="id" column="EVENT_ID" >
<generator class="increment"/>
</id>
<property name="dt" type="timestamp" column="EVENT_DATE"/>
<property name="title" column="TITLE"/>
</class>
</hibernate-mapping>
-----------------------------------------------------------------------------------
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.url">jdbc:oracle:thin:@172.17.8.52:1521:IFHT03</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<!--property name="hibernate.connection.datasource"> java:comp/env/jdbc/HibAppDS</property-->
<property name="hibernate.connection.username">daweb_user</property>
<property name="hibernate.connection.password">daweb_user</property>
<property name="hibernate.connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.OracleDialect</property>
<property name="show_sql">true</property>
<!--property name="hibernate.hbm2ddl.auto">select</property-->
<property name="hibernate.hbm2ddl.auto">create</property>
<property name="current_session_context_class">thread</property>
<property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory
</property>
<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider
</property>

<mapping resource="events/Event.hbm.xml"/>
<mapping resource="events/Person.hbm.xml"/>

</session-factory>
</hibernate-configuration>
-------------------------------------------------------------------------------

Anybody see an error on these ? Please

should say
<many-to-many column="EVENT_ID" class="events.Event"

Yes, that worked. Thank you very much.

Silly me !!
