Estoy tratando de crear un prototipo de un código de Hibernate bastante simple que se origina en un tutorial y obtengo un error que no entiendo profundamente en cglib2 (el seguimiento de la pila completa se encuentra al final de esta publicación). Probablemente estoy tratando de crear 'productBoProxy' por mi simpleprincipal( y bean XML (abajo).

He probado muchas versiones diferentes de cglib en vano. Estoy muy agradecido con cualquiera que pueda ayudarme a encontrar el camino correcto para resolver esto.

App.java:

ApplicationContext appContext
    = new ClassPathXmlApplicationContext( "resources/config/BeanLocations.xml" );
...
productBo = ( ProductBo ) appContext.getBean( "productBoProxy" );
productBo.save( product, 100 );

Product.xml:

...
<!-- This is a proxy factory bean; see App.java -->
<bean id="productBoProxy"
      class="org.springframework.aop.framework.ProxyFactoryBean">
  <property name="target" ref="productBo" />
  <property name="interceptorNames">
    <list>
      <value>transactionInterceptor</value>
    </list>
  </property>
</bean>
...
