I ended up walking resource myself:
private void visit(Resource resource) {
//actually do something.. like, adding to sitemap.
}
public void walkBreathFirst(Resource resource) {
final Queue<Resource> toVisit = new
ConcurrentLinkedQueue<Resource>();
try {
toVisit.add(resource);
while (!toVisit.isEmpty()) {
final Resource visitedResource = toVisit.remove();
visit(visitedResource);
final Iterator<Resource> iter =
visitedResource.listChildren();
while (iter.hasNext()) {
toVisit.add(iter.next());
}
}
} catch (SitemapException e) {
}
}
