Those are real world use cases, but there are as many use cases as Java developers... Self contained libs is the easiest way to deal with classloading stuff. We also realize that people do not want to copy/move libs around just to see an example running. You can share libs, but your different web apps may require different versions of the same libs. we decided to provide shared myfaces libs in JBoss AS, it's cool for some people, it's a pain for others who prefer to embed their own libs.
