You want to use sakai's specific way of doing this:
<bean id="ospPresentationHibernateMappings"
class="org.sakaiproject.springframework.orm.hibernate.impl.AdditionalHibernateMappingsImpl">
<property name="mappingResources">
<list>
<value>org/theospi/portfolio/presentation/model/impl/PresentationImpl.hbm.xml</value>
</list>
</property>
</bean>
For a full example see
https://source.sakaiproject.org/svn/osp/trunk/presentation/component/src/webapp/WEB-INF/components.xml
