General talk about software patterns

I agree, class loaders are the answer (in particular 
java.net.URLClassLoader). However, they are pretty low-level. For a more 
declarative way to deal with the problem check technologies like 
WebStart/JNLP or OSGi. In OSGi, bundles have an update URL and the OSGi 
runtime does the update for you.
