I tested same classes/config using stand alone test program and they are working fine. But when i deploy same in jboss server, i am getting this problem.

I searched a lot in google and found lot of similar issues but somehow did not get solution.

Please help me.

Thanks

This issue is happening because session factory was created through jboss and used with spring services. Some class loader issue. I am not very sure about root cause. I got it working by setting up hibernate session factory through Spring's org.springframework.orm.hibernate3.LocalSessionFactoryBean.

Code:
   <jee:jndi-lookup id="myDS" jndi-name="java:/MYDS"/>
      
   <bean id="hibernateSessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
      <property name="dataSource" ref="myDS"/>
      
      <property name="mappingResources">
         <list>
            <value>com/adp/ebs/admin/crs/dvo/CRSAuditInfo.hbm.xml</value>
         </list>
      </property>
      <property name="hibernateProperties">
         <value>
            hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
            hibernate.show_sql=true
            hibernate.current_session_context_class=thread
         </value>
      </property>

   </bean>
      
   <bean id="AuditService" class="com.adp.ebs.admin.services.crs.AuditServiceImpl">
         <property name="sessionFactory">
            <ref bean="hibernateSessionFactory"/>
         </property>
    </bean>



Thanks
