Come to think of it... Your point is really important. However, the
solution is a bit more drastic than I'd like it to be.
That is, I would like to use commit option A as much as possible.
Because it's more efficient for one thing!
Through the other application, I _know_ when the beans are to be
invalidated... I'd like to inform JBoss of that so that
all beans are flagged as needing a reload...
Can you suggest something closer to that "spec"? :)

I think you should look up "commit options" from the EJB spec, it
answers
your question :)
