I dont see any log messages at . I was assuming the interceptor would be called when i execute getHibernateTemplate().update(ffe) method in DAO class.




My session-factory.xml file looks like this
<bean id="freeFlagErrorSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource-etrans"/>
</property>
<property name="mappingResources">
<list>
<value>com/wmg/digital/esdc/freeflag/domain/FreeFlagError.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">

<property name="entityInterceptor">
