Subject Re: Multicast, redelivery and error handlers
Date Thu, 13 Sep 2012 07:04:58 GMT
Thanks for the fast response Claus.  I figured that must have been the
case, which is why I then tried implementing the timeout method on a
TimeoutAwareAggregator.  I thought if I called setException there (just
with a plain new Exception) then that might trigger the error handler.

I should describe that what I want to happen is that either the whole
multicast tries again, or perhaps just the one that timed out.  Is there a
different way of achieving that?
Thanks again,
James
