将对象传递给客户端调用的servlet

Question

我有一个桌面应用程序通过以下方法调用servlet：

    public int[] identify(String path) {

    try {

        URL url = new URL("http://localhost:8084/my-webapp/upload");
        URLConnection conn = url.openConnection();
        conn.setDoOutput(true);

        BufferedWriter out = new BufferedWriter(new OutputStreamWriter(conn.getOutputStream()));

        out.write("path=" + path);
        out.flush();
        out.close();
        BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));

        String response;
        while ((response = in.readLine()) != null) {
            int[] numbers = convertOutput(response);
            s.showOutput(numbers);
            return numbers;
        }
        in.close();
    } catch (MalformedURLException ex) {
        ex.printStackTrace();
    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        return null;
    }

我没有jsp文件。它由桌面应用程序执行，并且可以正常运行。但是现在当我调用我的servlet时，我需要将一个我之前实例化过的对象传递给servlet。我怎么能这样做？
