Ah, you are concerned about updates, a not-unreasonable concern. Well, you could get *really* fancy with classloaders and checking versions, then store the single jar, versionized, in /shared/lib, then declare your version in web.xml as a context param or within JNDI for that context.
Another option, probably easier, is to store the entire set in JNDI (either internal or external), and lookup the classes dynamically from JNDI. You would declare the JNDI context address in the web.xml, with the version part of the path.
