Rafael,
You could use annotations to describe the mappings but if not use the
following. Since you are using Spring you can use their Hibernate
support to look for mapping files in a particular directory. This way
you don't have to call them out in the hibernate file. Lookup
org.springframework.orm.hibernate3.LocalSessionFactoryBean. Here is an
example:
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.cache.provider_class">
org.hibernate.cache.HashtableCacheProvider
</prop>
<prop key="hibernate.dialect">
org.hibernate.dialect.Oracle10gDialect
</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.format_sql">false</prop>
</props>
</property>
<property name="mappingDirectoryLocations">
<list>
<value>
classpath*:/org/myexample/server/dao/hibernate
</value>
</list>
</property>
</bean>
The mappingDirectoryLocations property tells spring to look for
hbm.xml files in the org.myexample.server.dao.hibernate package. Then
you need a *.hbm.xml for each table and the relationships are defined
in those files. You also need a datasource described in your
application context.
Hope this helps.
