You're very close to having this challenge done. The jsonData object was already created for you in some hidden wrapper code, which is what the comments were referring to. All you need to do to finish this is to remove the line:

JSONObject jsonData= new JSONObject(data.json.string());

and you should be able to pass the challenge. Please let us know if this helps or not so we can help further if you need it. Also please try to provide updated code if you do need more assistance so we can help you from your current setup.
