I am using hibernate Envers (version 3.5.6) with JPA and Spring 3. I have below setting in my spring settings (applicationcontext.xml)

<bean id="enversListener" class="org.hibernate.envers.event.AuditEventListener"/>
<bean id="mySessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="packagesToScan" value="com.wipro.edo.entities" />
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
hibernate.connection.pool_size=10
hibernate.temp.use_jdbc_metadata_defaults = false
hibernate.show_sql = true
hibernate.hbm2ddl.auto = update
</value>
</property>
<property name="eventListeners">
<map>
<entry key="post-insert">
<ref local="enversListener"/>
</entry>
<entry key="post-update">
<ref local="enversListener"/>
</entry>
<entry key="post-delete">
<ref local="enversListener"/>
</entry>
<entry key="pre-collection-update">
<ref local="enversListener"/>
</entry>
<entry key="pre-collection-remove">
<ref local="enversListener"/>
</entry>
<entry key="post-collection-recreate">
<ref local="enversListener"/>
</entry>
</map>
</property>
</bean>

In the logs , I do see org.hibernate.envers.DefaultRevisionEntity getting called. I do not see the AuditEventListener getting initialized, the audit tables are also not getting created inspite of having hibernate.hbm2ddl.auto = update as mentioned above. In terms of the jars , I use :

1.hibernate-core-3.5.6-Final.jar
2.hibernate-entitymanager-3.5.6-Final.jar
3.hibernate-envers-3.5.6-Final.jar
4.hibernate-jpa-2.0-api-1.0.0.Final.jar

When I insert/update any @Audited entity, I do see the audited tables being mentioned as being binded by the hbmbinder :
19.04.2012 20:13:36 *DEBUG* HbmBinder: Mapped property: REVTYPE -> REVTYPE (HbmBinder.java, line 1335)
19.04.2012 20:13:36 *DEBUG* HbmBinder: Mapped property: REVTYPE -> REVTYPE (HbmBinder.java, line 1335)
19.04.2012 20:13:36 *INFO * HbmBinder: Mapping class: com.wipro.edo.entities.EDOPermission_AUD -> tbl_Permission_AUD (HbmBinder.java, line 348)
19.04.2012 20:13:36 *INFO * HbmBinder: Mapping class: com.wipro.edo.entities.EDOPermission_AUD -> tbl_Permission_AUD (HbmBinder.java, line 348)

I do not see the audit tables nor the entries in the database, would be great if anyone can offer a clue.Please do also let me know if more information is needed.
