Hibernate, transactions and cglib

[n2000]

In my application i use Hibernate and Spring declarative transaction management. When i activate transactions Hibernate uses cglib which causes LazyInitializationException when i access simple properties (no lists!) in my Hibernate classes. When i disable transactions i don't get these errors.

How can i disable usage of cglib in hibernate when i use declarative transaction management?

Thanks for your help!


Some more details:

I tried these ways to disabled cglib in hibernate with no success:

I added hibernate properties to bean configuration:

<bean id="hibernateProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
  <property name="properties">
    <props>
    ...
    <prop key="hibernate.bytecode.use_reflection_optimizer">false</prop>
    <prop key="hibernate.cglib.use_reflection_optimizer">false</prop>
    ...                  
   </props>
  </property>
</bean>

I used the VM parameter:

-Dhibernate.bytecode.use_reflection_optimizer=false 
-Dhibernate.cglib.use_reflection_optimizer=false

I also created a hibernate.properties file in my classpath:

hibernate.bytecode.use_reflection_optimizer=false
hibernate.cglib.use_reflection_optimizer=false

There is an old related posting with no solution: forum.springsource.org/showthread.php?p=215797 (I am not allowed to post real URLs here...).

Versions:

• Spring-2.0.7
• Hibernate-3.2.6.GA

Here is my transaction configuration:

<tx:advice id="defaultTxAdvice" transaction-manager="txManager">
   <tx:attributes>
      <tx:method name="find*" read-only="true"/>
      <tx:method name="*"/>
   </tx:attributes>
</tx:advice>

<tx:advice id="noTxAdvice" transaction-manager="txManager">
   <tx:attributes>
      <tx:method name="*" propagation="NEVER"/>
   </tx:attributes>
</tx:advice>

<aop:config proxy-target-class="false">
   <aop:pointcut id="dictionaryHandlerTx" expression="execution(* com.carano.ml.handler.*HandlerImpl.*(..))" />
   <aop:advisor advice-ref="defaultTxAdvice" pointcut-ref="dictionaryHandlerTx" />
</aop:config>

<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
   <property name="dataSource" ref="fltutf8DataSource" />
</bean>
