Applet can not read from servlet because of java.io.EOFException

Question

Hi all,
i try to communicate my applet with a servlet. i examine lots of codes from internet and i did lots of things to get a working sample but i couldn't sucess on this work for 2 days so if anyone can help me i will be very happy.
Anyway, here is the code snippets :
1- Applet side code to send data (serializabed object) to servlet :
   // Opening connection...
   URL urlServlet = new URL("http", "81.214.190.3", 8080, "/pwta/pwtax");
   URLConnection connection = urlServlet.openConnection();
   // Setting attributes...
   connection.setDoInput(true);
   connection.setDoOutput(true);
   connection.setUseCaches(false);
   connection.setDefaultUseCaches(false);
   connection.setRequestProperty("Content-Type",
                                                              "application/octet-stream");
   OutputStream outputStream = connection.getOutputStream();
   ObjectOutputStream objectOutputStream = new ObjectOutputStream (outputStream);
   objectOutputStream.writeObject(islem);
   objectOutputStream.flush();
   objectOutputStream.close();
   // Receiving result from servlet...
  // Exception is thrown at line 71! Detail is written at bottom of message!
  InputStream inputStream = con.getInputStream(); // line 71 is here!!!
  ObjectInputStream objectInputStream = new ObjectInputStream(inputStream);
  returnValue = (Sonuc) objectInputStream.readObject();
  objectInputStream.close();
  inputStream.close();
2- Server side code which read data and sendit after processing  to   applet  :
// Reading requirement... Implementation is done in doPost() method!
    InputStream in = request.getInputStream();
    ObjectInputStream inputFromApplet = new ObjectInputStream(in);
    Islem islem = (Islem) inputFromApplet.readObject();
    inputFromApplet.close();
    // Doing the required job!
   setMapperAndDoTheJob(islem);
   // Writing the result to user...
   OutputStream outstr = response.getOutputStream();
   ObjectOutputStream oos = new ObjectOutputStream(outstr);
   oos.writeObject(sonuc);
   oos.flush();
   oos.close();
//  *************************************************************************When i run my applet the following exception is thrown :
java.io.EOFException
at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source)
at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source)
at java.io.ObjectInputStream.readStreamHeader(Unknown Source)
at java.io.ObjectInputStream.<init>(Unknown Source)

Answer 1

get it working using a text transfer before you use and object transfer
