I've encountered the same issue resently. I'm using linux, sun jdk1.6
and have tried undeploying a ear with the cli deployer both in 2.1.3 and
2.1.4-SNAPSHOT.

My ear contains a web app, some mdb:s and stateless ejb modules.

As far as I can tell the application is properly deployed and runs
fine. When I undeploy both the deploy.sh process and the undeploy
in geronimo seems to hang. In the log file, the last message is this

11:07:14 INFO  [startup] Undeploying app: /opt/geronimo-jetty6-javaee5-2.\
    1.3/var/temp/geronimo-deploymentUtil2956946420796194584.jar

I've found that if i shut down geronimo it is possible to do a offline
undeploy using deploy.sh -o undeploy, so no need to do it manually in
the repository direcotry like others in this thread.

Guess what? Before reading your reply, I re-installed geronimo, and
the very same ear that previosly refused to redeploy now redeploys
just fine.

I believe this is what has happened: At one stage my ear was severely
broken and failed to deploy properly. After offline undeploying at
that stage, geronimo was broken, but only just enough to still allow
new deploys, execution, and offline undeploys, but not allowing online
undeployment or redeployment anymore.

Yep, the unfortunate impression I've got is that geronimo can be a bit
brittle in deployment and undeployment when the application is not
well behaved (correct/spec compliant). I can understand that, but the
thing is, during development an application seldom is 100 percent correct,
so failed deploys is more or less bound to happen.

Now, I've had this happen on other geronimo deployed projects before,
so next time it happens I know what to look for and I'll raise a issue.

That would be great.

Probably, however I don't recall anybody actively working on them.  
Afraid the tendency is to fix the deployment problem, then never quite  
get back to fixing the undeploy problem (which is really a 'deploy'  
problem). If you or anybody else has specific instances where  
deployment can't be undeployed, please raise a jira. And if anybody is  
interested in pitching in with some coding/debuggnig, this might be an  
interesting area to look into...

I'm eager to help, of course. Let me see if I can pull togheter a ear
that hangs, and that I can share. Should I create a new jira issue?

Btw, are there any other "known issues" in this area? Like the one
David mentioned, that apps that are not properly loaded hangs on
undeployment.

Running offline undeploy is a good idea.

Would be really nice, however, to pin down the source of your online  
undeploy hang. Can you share the application that will illustrate the  
problem?
