json - how to create insert new nodes in JsonNode?

Question

I have a new JsonNode that I created

JsonNode jNode = new ObjectCodec().createObjectNode();

with this node, how do I then add key value pairs within so that I can construct this new node with the new values? What I read in http://www.cowtowncoder.com/blog/archives/2011/08/entry_460.html mentioned about using

jNode.with("newNode").put("key1","value1");

But looking at the APIs for Jackson's JsonNode (v1.8) does not show any method as such.

Answer 1

These methods are in ObjectNode: the division is such that most read operations are included in JsonNode, but mutations in ObjectNode and ArrayNode.

Note that you can just change first line to be:

ObjectNode jNode = mapper.createObjectNode();
// version ObjectMapper has should return ObjectNode type

or

ObjectNode jNode = (ObjectNode) objectCodec.createObjectNode();
// ObjectCodec is in core part, must be of type JsonNode so need cast
