json + idee api problem

Hello!

I try to get String data from JSON from multicolr, and I cannot seem to extract it. I was using this and this as my reference, but everything I try returns an error.

I include my JSON output lower down the post.

I also include a piece of JavaScript which works for that web which inspired me.

I guess the problem is that I dont adress the {objects} properly, but I am extremely new to this ( week of coding ) and i can't really use Java Docs or udnerstand how Java syntax for libraries applies for Processing.

import org.json.*;
color colorOne = color(int(random(1, 255)), int(random(1, 255)), int(random(1, 255)));
String col = ( hex( colorOne, 6 ));
String url = "http://labs.ideeinc.com/rest/?method=flickr_color_search&limit=60&offset=0&colors[0]=" + col + "&weights[0]=1";
void setup() {
getOJ();
};
void getOJ() {
try {
JSONObject idee = new JSONObject(join(loadStrings(url), ""));
//println(idee.toString(2));
JSONArray results = idee.getJSONArray("result");
//println("results: " + results.toString(2) );
String filepath = idee.getString("filepath");
// I also tried
// String filepath = results.getString("filepath");
}
catch (JSONException e) {
println ("json parsing error");
};
};

JSON:

{
"error": [],
"method": "flickr_color_search",
"result": [

json += line;

var data = Json.decode(json);
var i = 0;
for (n in data.result) {
url = new java.net.URL(data.result[n][1]);
var image = new PlacedFile(url);
image.bounds.width = 80;
image.bounds.height = 80;
image.bounds.center = new Point(i*81, Math.floor(i/10)*81);
document.redraw();
i++;

Got the fix from my friends, will paste it in case anyone has problems with JSON syntax

import org.json.*;
color colorOne = color(int(random(1, 255)), int(random(1, 255)), int(random(1, 255)));
String col = ( hex( colorOne, 6 ));
String url = "http://labs.ideeinc.com/rest/?method=flickr_color_search&limit=60&offset=0&colors%5B0%5D=" + col + "&weights%5B0%5D=1";
void setup() {
getOJ();
};
void getOJ() {
try {
JSONObject idee = new JSONObject(join(loadStrings(url), ""));
println(idee.toString(2));
JSONArray results = idee.getJSONArray("result");
String filepath = results.getJSONObject(0).getString("filepath");
println (filepath);
}
catch (JSONException e) {
println ("json parsing error");
};
};
