And would you get the handle to the other Manager in the same way we do
for daos, using spring injection?
Yes.

Where is this set? I've tried to update my AppFuse1.9.4 based app to
use spring2, and I'm now thinking that I may have done that incorrectly...
The following line does this:
<aop:advisor id="managerTx" advice-ref="txAdvice"
pointcut="execution(* *..service.*Manager.*(..))" order="2"/>
It basically says, wrap any interface in the service package that ends
with "Manager" with a transaction. Because of this, it's important to
set your dependencies to interfaces, not to implementations.

My applicationContext-service.xml begins with:

</tx:advice>
This is definitely an area where I've not taken the time to read enough
to feel that this is anything other than magic, so any advice would be
appreciated...
