  Modified:    catalina/src/share/org/apache/naming/resources
                        DirContextURLConnection.java
  Log:
  - Add a new list call which returns an enumeration of names of the children of
    a collection. Since that call isn't part of the URLConnection methods, the
    URL connection returned by getResource(path).openConnection() needs
    to be typecast.
