ClassLoaders in Embedded:
We just use the plain old super simple System Classloader. The web
container does its own fancy complicated class loading stuff which is
completely independent of embedded vs. non-embedded.
AFAIK you should never have to put a jar that is already inside a
deployed war into the System Classloader. You don't have more than one
web app accessing the jar - right? You aren't accessing any classes
from the jar "outside" of the webapp - right?
Jan - do you have any ideas about this?
Sorry to badger you (Jan) again but you are the Guru in this area!

That JAR file is indeed in the WAR file in the WEB-INF/lib directory. But if I do not include the same JAR file on the classpath used to start my java application (that starts the server) I get a NoClassDefFoundError exception.
