Functionally I don't think there is a difference between jars and classes. 

>From a management prospective however, the jar solution implies that
collection of classes has a separate development life cycle from the
webapp.  If you fix some problem in the classes, just rebuild and
distribute the jar file.  Provided you didn't make a breaking change,
customers should just be able to drop in the updated jar and restart the
webapp.  A collection of classes splayed out in the classes folder
creates a more challenging update scenario.

In the case you describe above, the jar solution makes it easy to update
a number of webapps with different configs.
