Jackson JSON: get node name from json-tree

Question

How can I receive the node names from a JSON tree using Jackson? The JSON-File looks something like this:

{  
    node

For Jackson 2+ (com.fasterxml.jackson), the methods are little bit different:

Iterator> nodes = rootNode.get("foo").fields();

while (nodes.hasNext()) {
  Map.Entry entry = (Map.Entry) nodes.next();

  logger.info("key --> " + entry.getKey() + " value-->" + entry.getValue());
}
