An app can invoke the GlassFish REST interface to do this. However,
since the running app will be disabled as part of the operation, it
wouldn't be able to report results to the user. Another idea might be
to have a companion "upgrade" app. The main app could redirect the
upgrade request to the upgrade app, which would then upgrade the main
app and report the results. Essentially, the "upgrade" app is acting
like a mini-console. The main app could upgrade the upgrade app.
