只要只有您的applet与服务器通信，就可以使用序列化对象。您只需要在applet
jar和服务器上维护相同版本的对象类。它不是最开放或可扩展的方法，但可以快速达到开发时间，而且非常可靠。
这是一个例子。
实例化与Servlet的连接
URL servletURL = new URL("<URL To your Servlet>");URLConnection servletConnect = servletURL.openConnection();servletConnect.setDoOutput(true); // to allow us to write to the URLservletConnect.setUseCaches(false); // Write the message to the servlet and not from the browser's cacheservletConnect.setRequestProperty("Content-Type","application/x-java-serialized-object");获取输出流并编写您的对象
MyCustomObject myObject = new MyCustomObject()ObjectOutputStream outputToServlet;outputToServlet = new ObjectOutputStream(servletConnection.getOutputStream());outputToServlet.writeObject(myObject);outputToServlet.flush(); //CleanupoutputToServlet.close();
现在阅读回应
ObjectInputStream in = new ObjectInputStream(servletConnection.getInputStream());MyRespObject myrespObj;try{ myrespObj= (MyRespObject) in.readObject();} catch (ClassNotFoundException e1){ e1.printStackTrace();}in.close();在您的servlet中
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{ MyRespObject myrespObj= processSomething(request); response.reset(); response.setHeader("Content-Type", "application/x-java-serialized-object"); ObjectOutputStream outputToApplet; outputToApplet = new ObjectOutputStream(response.getOutputStream()); outputToApplet.writeObject(myrespObj); outputToApplet.flush(); outputToApplet.close();}private MyRespObject processSomething(HttpServletRequest request){ ObjectInputStream inputFromApplet = new ObjectInputStream(request.getInputStream()); MyCustomObject myObject = (MyCustomObject) inputFromApplet.readObject(); //Do Something with the object you just passed MyRespObject myrespObj= new MyRespObject(); return myrespObj;}只要记住，您传递的两个对象都需要实现可序列化
public Class MyCustomObject implements java.io.Serializable {
