Stephen, i know it is a spring xml file. i can tell that with the <bean id="transactionManager".../> element, they are defining a transaction manager. however, what does <tx:annotation-driven transaction-manager .../> do? to me, intuitively, it defines a transaction manager that will process by annotations.
the tutorial that gives this applicationContext.xml shows us how to get things working, but doesn't really explain in detail "why" we are doing what we are doing. that's kind of what i meant.
