The transaction attributes would be centralized though, in contrast to TransactionProxyFactoryBean that keeps them local per individual proxy definition.

Hi Juergen,

How do you see this being used (if at all) with the current 
TransactionInterceptor, since its TransactionAttributeSource property 
gets satisfied via a MethodMapTransactionAttributeSource instance (which 
needs definitions in the format 'FQN.methodName'). While this works fine 
when doing individual interceptors for use with ProxyFactoryBean, short 
of adding new code I'm at a loss as to how I could use 
TransactionInterceptor with BeanNameAutoProxy to do transactions on all 
methods in all the beans I feed to the auto proxy.

Just wondering if I missed something?

Colin
