Dispatcher has no subscribers: Not in IDE, only when deployed to Websphere?!
i have a junit test and a webapp which execute the same SI 2.0.5 (Spring 3.0.5) code successfully in STS and RAD
(war under tomcat in STS, ear under websphere in RAD),
but when i build the code into an ear using ant and deploy to websphere (6.1.x) "proper",
i get:
Code:
[1/19/12 12:58:08:690 EST] 0000004f SystemErr R Caused by: org.springframework.integration.MessageDeliveryException: Dispatcher has no subscribers.

there are some specific details about code, build scripts and websphere that i can look into,
but before i potentially go on a witch hunt, i figured i'd go bumming for suggestions as to what might lead to
this disparate behavior across environments (vs i just flubbed the configuration and it has never worked).
for instance, in my preliminary investigation, i came across some mention of SmartLifecycle. I'm not familiar with this,
so i haven't made use of it explicitly, could not paying attention to that cause subtle timing differences in different environments that could lead to this condition? if so, how might i hook into the SmartLifecycle to affect this?
any suggestions appreciated,
tony.
