The root of a jar, '/', doesn't actually exist as an entry in the jar. I added a "/" atom object in the jarentryinfo class. So now when you go to navigate the jar using the jarentryinfo class, the root element appears to exist. This allows for visiting a jar starting at the root. The jar entry test would have to be updated since it doesn't expect the root element to be there. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054021#...
