My application runs in tomcat and I can deploy and undeploy my app and
the database is fine and I'm able to reconnect.  Are you unloading the
database when you undeploy?

If you are using embedded derby, as far as I know, you can only have
one active connection to it at a time.

You might be able to get around this using JNDI data sources, which I
think ties the connection to tomcat and not to your application.  I
haven't confirmed this, but it is worth a shot if you're not already
doing it (and a better practice as well).

Good luck!
