Is there a reason that you are using 'java -jar' to run the deploy command, rather than the
bin/ (or .bat) shell script? It does set a few options (e.g. geronimo.home.dir and I don't think this is causing your error, but 'java -jar' would not be my
recommended technique for running the deploy command...

Well, the server should not be behaving this way. Clearly there's something in the ear file
which is causing a deployment failure. But even with this problem, the server should be a
bit more resilient and doing a better job indicating the cause of the problem to the deploy
command and cleaning up the application on the server...

Are there any errors in the server or deployer log files in var/log? I would expect something
to show up there... if you can post a test ear file that illustrates the problem, somebody
could look at it for you. I'm guessing you can't make the app available, however...
