Applet和Servlet之间传递对象是，Applet出现java.io.EOFException,请问怎么解决?????

Question

给你个例子,看看吧
servlet端
/**
 * type class' function
 * 
 * @author Likestar
 */
public class ServletToApplet extends HttpServlet { protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
response.setCharacterEncoding("GBK");
try {
PrintWriter out = response.getWriter();
out.println(" ");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
protected void service(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
response.setContentType("application/octest-stream");
try {
ObjectInputStream in = new ObjectInputStream(request.getInputStream());
Object obj = in.readObject();
in.close();
ObjectOutputStream out = new ObjectOutputStream(response.getOutputStream());
out.writeObject("成功");
out.flush();
out.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//System.out.println(obj);
} public static void main(String[] args) {
}
}
