Cannot rollback tx when using TransactionProxyFactoryBean [Archive]

Hi all,
I have encountered a problem when using Spring Transaction Management feature.
The following sources are based on the example petClinic sources.
But the TransactionProxyFactoryBean seem go wrong (maybe) when I intentionally throw a DataAccessException in storeComposite method.
The transaction still commit instead rollback.
Please help me. Thank you
