The common problem users have are adding values to the classpath AFTER the daemons had been
started. If you are getting ClassNotFound exception and are 100% sure you have correctly specified
path to the jar files and your jar files actually have the compiled class then simply restart
the daemons s that they can pick up new configuration.
