        throws JSONException, org.codehaus.jettison.json.JSONException,
        IOException {
    Yaml.dump(Yaml.dump(JsonToMap.jsonToMap(json)), new File("config.yml"));
    BufferedReader br = new BufferedReader(new FileReader("config.yml"));
    String line;
    studioName = studioName.toLowerCase();
    File writeFile = new File("sudo /var/iprotecs/idns2.0","" + studioName + ".yaml");
    FileOutputStream fos = new FileOutputStream(writeFile);
    BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(fos));
    try {
        while ((line = br.readLine()) != null) {
            String line1 = line.replace(""", "");
            String line2 = line1.replaceAll("!java.util.HashMap", "");
            String line3 = line2.replaceAll("---", "");
            String line4 = line3.replace("|", "");
