URLArchive

public class URLArchive extends Object implements Archive
This is an implementation of {@link Archive} when container returns a url that is not one of the familiar URL types like file or jar URLs. So, we can not recurssively walk thru' it's hierarchy. As a result {@link #getEntries()} returns an empty collection.
