准备用Applet向Servlet提交对象，用对象流
请问这么些为什么会有问题？

Applet:

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
import javax.swing.*;
import java.net.*;
import java.io.*;


public class Applet1 extends JApplet {
        //Initialize the applet
        public void init() {
                try {
                URL url = new URL("http://localhost:8080/servlet1");
                URLConnection con = url.openConnection();
                con.setDoOutput(true);
                test tt = new test();
                tt.a1="dddddddddd";
                tt.a2="dddddfasd";
                OutputStream out = con.getOutputStream();
                ObjectOutputStream objStream;
                objStream = new ObjectOutputStream(out);

                objStream.writeObject(tt);
               }
                catch(Execption e){}

        }
  }

Servlet1:

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;



public class Servlet1 extends HttpServlet {
        private static final String CONTENT_TYPE = "text/html; charset=GBK";
        //Initialize global variables
        public void init() throws ServletException {
        }
        //Process the HTTP Get request
        public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
                response.setContentType(CONTENT_TYPE);

                        InputStream in = request.getInputStream();
                        ObjectInputStream objStream;
                        objStream = new ObjectInputStream(in);
                        test tt =  new test();
                        try{
                         tt = (test)objStream.readObject();
                        }
                        catch(ClassNotFoundException e)
                        {
                        }

                        System.out.println(tt.a1+tt.a2);
        }
        //Clean up resources
        public void destroy() {
        }
}

test:
public class test {
        String a1="aaaa";
        String a2="bbbb";
}

你用的是什么服务器?  tomcat?

可能是你的 servlet 路径设置不对吧, 没有联上.
