Servlet Applet object communication problem???!!!

Question

Hy folks,
I need to validate the ability of complex Servlet Applet communication an run into my first pb right at the beginning of my tests. I need to have around 200 Applet clients connect to my servlet and communicate by ObjectInput and ObjectOutput streams. So I wrote a simple Servlet accepting HTTP POST connections that return a Java object. When the java Applet get instantiated, the Object Stream communication workes fine. But when the Applet tries to communicate with the servlet after that, I can not create another communication session with that Servlet, instead I get a 405 Method not allowed exception.
Summarized:
- Applet init() instantiate URLConnection with Servlet and request Java object (opening ObjectInput and Output Stream, after receaving object, cloasing streams).
- When I press a "get More" button on my Applet, I am not able to instantiate a new URLConnection with my servler because of that 405 exception, WHY???
Here my Servlet code:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
         ObjectInputStream inputFromApplet = null;
         ArrayList transmitContent = null;       
         PrintWriter out = null;
         BufferedReader inTest = null;
         try{               
               inputFromApplet = new ObjectInputStream(request.getInputStream());           
                 transmitContent = (ArrayList) inputFromApplet.readObject();       
                 inputFromApplet.close();
                 ArrayList toReturn = new ArrayList();                 
                 toReturn.add("One");
                 toReturn.add("Two");
                 toReturn.add("Three");
                 sendAnsweredList(response, toReturn);                 
         catch(Exception e){}        
     public void sendAnsweredList(HttpServletResponse response, ArrayList returnObject){
         ObjectOutputStream outputToApplet;    
          try{
              outputToApplet = new ObjectOutputStream(response.getOutputStream());          
              outputToApplet.writeObject(returnObject);
              outputToApplet.flush();           
              outputToApplet.close();              
          catch (IOException e){
                 e.printStackTrace();
}Here my Applet code:
public void init() {         
         moreStuff.addActionListener(new ActionListener(){
              public void actionPerformed(ActionEvent e){
                   requestMore();
         try{
              studentDBservlet = new URL("http://localhost/DBHandlerServlet");              
              servletConnection = studentDBservlet.openConnection();      
               servletConnection.setUseCaches (false);
               servletConnection.setDefaultUseCaches(false);
               servletConnection.setDoOutput(true);
               servletConnection.setDoInput(true);
               ObjectOutputStream outputToApplet;
             outputToApplet = new ObjectOutputStream(servletConnection.getOutputStream());          
             outputToApplet.writeObject(new ArrayList());
             outputToApplet.flush();           
             outputToApplet.close(); 
               ObjectInputStream inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
               ArrayList studentVector = (ArrayList) inputFromServlet.readObject();
               area.setText("Success!\n");
               for (int i = 0; i<studentVector.size(); i++) {
                    area.append(studentVector.get(i).toString()+"\n");
              inputFromServlet.close();
              outputToApplet.close();             
          catch(Exception e){
               area = new JTextArea();
               area.setText("An error occured!!!\n");
               area.append(e.getMessage());
        getContentPane().add(new JScrollPane(area), BorderLayout.CENTER);
        getContentPane().add(moreStuff, BorderLayout.SOUTH);
    private void requestMore(){
         try{              
              studentDBservlet = new URL("http://localhost/DBHandlerServlet");                             
              servletConnection = studentDBservlet.openConnection(); 
               ObjectInputStream inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
               ArrayList studentVector = (ArrayList) inputFromServlet.readObject();
               area.setText("Success2!\n");
               for (int i = 0; i<studentVector.size(); i++) {
                    area.append(studentVector.get(i).toString()+"\n");
          catch(Exception e){               
               area.setText("An error occured2!!!\n");
               area.append(e.getMessage());
    }Can someone help me solv this issue please, this is my first Applet Servlet work so far so I have no idea on how to solve this issue.

Sorry folks, just found my error. Forgot about the ObjectInputStream waiting on the Servlet side, so of course had a dead look...
Sorry!
