Load-time weaving without @Transactional annotation

Hello,

Working with SpringSource DM Server 2.0.0, I was used to use annotations to manage transactions, using <context:load-time-weaver aspectj-weaving="on" /> and <tx:annotation-driven mode="aspectj" /> to set up load-time weaving.

But one day I had to switch transaction management from @Transactional annotations to plain AOP interceptors (because of this problem).
And now I don't know how to set up load-time weaving. This section of the documentation says how to set up load-time weaving with AOP, but I don't know which aspects are used by the <tx:advice> tag, so I don't know how to configure my aop.xml file (if I need one).

This should be a quite common task so I guess I missed some obvious steps here.

Thanks,
GS
