I have a requirement in my project that i want to retrieve data from a JSON url like
localhost:8080/gwt-console-server/rs/process/instance/258/activeNodeInfo
I am trying to get the data from the jBPM workflow part. When i load this url i got the window with some display like,
[{"width":932,"height":541,"activeNode":{"name":"id\u003d13","x":662,"y":123,"width":118,"height":40}}]
I believe the values are there in the array. I want to store each of the values in different variables.
i used the code like,
try {
List<string> result = new ArrayList<string>();
String url = "http://localhost:8080/gwt-console-server/rs/process/instance/258/activeNodeInfo";
String json = HttpUtil.decodePath(url);
JSONObject resultJsonObject = new JSONObject(json);
JSONArray jsonArray = resultJsonObject.getJSONArray("results");
System.out.println("jsonArray-->"+jsonArray);
String name = null;
for (int index = 0, total = jsonArray.length(); index < total; index++) {
final JSONObject jsonObject = jsonArray.getJSONObject(index);
name = jsonObject.getString("name");
result.add(name);
}
System.out.println("result-->"+result);
} catch (JSONException e) {
throw new RuntimeException(e+"here");
}</string></string>
But this is not working. How can i do this in liferay??

Try following code
String json = HttpUtil.decodePath(url);
JSONArray jsonArray = JSONFactoryUtil.createJSONArray(json);
for (int index = 0;index < jsonArray.length(); index++) {
JSONObject jsonObject = jsonArray.getJSONObject(index);
System.out.println("width"+jsonObject.getString("width"));
System.out.println("width"+jsonObject.getString("height"));
JSONObject activeNodeJsonObject = jsonObject.getJSONObject("activeNode");
System.out.println("Name"+activeNodeJsonObject.getString("name"));
System.out.println("X"+activeNodeJsonObject.getString("x"));
System.out.println("Y"+activeNodeJsonObject.getString("y"));
}
