该部分主要涉及Applet和服务器通信的解决方案
基于B/S的Applet与服务器通信，最直接的方法是采用Applet/Servlet方式，该方式可以支持字节流和对象流两种通信方式：
Applet端代码：

• 字节流方式

1. 输出流对象：OutputStream out = con.getOutputStream();
2. 输入流对象：InputStream in = con.getInputStream();
   

参数上传
java.io.BufferedWriter writerStream = new java.io.BufferedWriter(new java.io.OutputStreamWriter(out));
          try{
              writerStream.write("Nice to meet you!");           
          } finally{
              writerStream.flush();
              writerStream.close();
          }
结果获取
BufferedReader textStream =new BufferedReader(new InputStreamReader(in));        
          String line1 = textStream.readLine();  
          String line2 = textStream.readLine();
          textStream.close();

• 对象流方式

参数上传
 java.io.ObjectOutputStream ows = new java.io.ObjectOutputStream(out);
          ows.writeObject(wwd.getMousePosition());
          ows.flush();
          ows.close();
结果获取
 java.io.ObjectInputStream ois = new java.io.ObjectInputStream(in);
          Point p = (Point) ois.readObject();
          ois.close();
Servlet端

参数获取
 javax.servlet.ServletInputStream sis = request.getInputStream();
  java.io.BufferedReader br = new java.io.BufferedReader(new java.io.InputStreamReader(sis));
        String varString = br.readLine();
        br.close();
结果发送
  PrintWriter out = response.getWriter();       
        try {
            out.println(varString);
            out.println("you find me!");           
        } finally {           
            out.close();
        }

• 对象流方式

参数获取
 javax.servlet.ServletInputStream sis = request.getInputStream();
java.io.ObjectInputStream ois = new java.io.ObjectInputStream(sis);
  java.awt.Point p = null;
        try {
            p = (java.awt.Point) ois.readObject();
        } catch (ClassNotFoundException ex) {
            Logger.getLogger(test.class.getName()).log(Level.SEVERE, null, ex);
        }
结果发送
  java.io.ObjectOutputStream oos = new java.io.ObjectOutputStream(response.getOutputStream());
        oos.writeObject(p);
        oos.close();
