On occasion I have need from my app to update the
web.xml and cause the app to get restarted. I tried
to do this using the manager application and found
that whenever the reload command is issued from a
servlet in the target app (the one to be reloaded) it
causes the manager and target apps to hang:
2001-10-22 16:32:34 StandardWrapper[/AGCW:Manager]: Loading
container servlet Manager
2001-10-22 16:32:34 Manager: init
2001-10-22 16:32:34 Manager: init: Associated with Deployer
'localhost'
2001-10-22 16:32:34 Manager: restart: Reloading web application at
'/AGCW'
2001-10-22 16:32:34 StandardContext[/AGCW]: Reloading this Context
has started
2001-10-22 16:32:34 StandardWrapper[/AGCW:Manager]: Waiting for 1
instance(s) to be deallocated
the last entry indicates the hanging servlet.
If I issue the command from somewhere other than the target app,
it completes normally:
2001-10-23 17:29:09 StandardWrapper[/manager:Manager]: Loading

2001-10-23 17:29:09 Manager: init

Allowing an app to restart itself seems like an important use of this
function.
I'd call this a bug.
