JSON对象未在IDE外部创建

Question

我正在使用JSON对象发送HTTP Post请求。我的程序在IDE中运行得非常好，但是当我从桌面上的JAR文件运行它时，它会卡住。
代码

        if ((act.getSource() == sendAlertButton)) {

            JOptionPane.showMessageDialog(null, "Inside send alert button handler");

            //Creating JSON
            JSONObject mainObj = new JSONObject();
            JOptionPane.showMessageDialog(null, "Created main object");

            //Handles access token
            mainObj.put("access_token", *access token*);
            JOptionPane.showMessageDialog(null, "Created access token");

            //Handles file format
            mainObj.put("format", "json");
            JOptionPane.showMessageDialog(null, "Created format");

            //Handles alarm
            JSONObject alarmObj = new JSONObject();
            //Fill alarmObj
            JOptionPane.showMessageDialog(null, "Created alarm fields");

            //Handles event
            JSONObject eventObj = new JSONObject();
            //Fill eventObj

            JOptionPane.showMessageDialog(null, "Created event fields");                
            JOptionPane.showMessageDialog(null, "JSON Object created successfully");

            //Send Post
            Map<String, String> headerMap = new HashMap<String, String>();
            String bodyStr = mainObj.toString();
            InputStream body = new ByteArrayInputStream(bodyStr.getBytes());
            //System.out.println("Sending Post");
            post(*IP address*, headerMap, body);

            JOptionPane.showMessageDialog(null, "Alert sent successfully!");

        }

它永远不会输出＆＃34;创建的主要对象＆＃34; ，所以我知道它会卡在JSONObject mainObj = new JSONObject();上 线。任何想法为什么只有当我在IDE之外运行它时才会发生这种情况？
