Ich habe den folgenden Code auf der Applet-Seite:

URL servlet = new URL(appletCodeBase, "FormsServlet?form=requestRoom");
URLConnection con = servlet.openConnection();

con.setDoOutput(true);
con.setDoInput(true);
con.setUseCaches(false);
con.setRequestProperty("Content-Type", "application/octet-stream");

ObjectOutputStream out = new ObjectOutputStream(con.getOutputStream());
out.writeObject(user);//user is an object of a serializable class
out.flush();
out.close();

ObjectInputStream in = new ObjectInputStream(con.getInputStream());
status = (String)in.readObject();
in.close();
if("success".equals("status")) {
    JOptionPane.showMessageDialog(rootPane, "Request submitted successfully.");
} else {
    JOptionPane.showMessageDialog(rootPane, "ERROR! Request cannot be made at this 
    time");
}

uf der Servlet-Seite erhalte ich den Code wie folgt:

    form = request.getParameter("form");
    if("requestRoom".equals(form)) {
        String fullName, eID, reason;
        UserRequestingRoom user;

        try {
            in = new ObjectInputStream(request.getInputStream());
            user = (UserRequestingRoom)in.readObject();
            fullName = user.getFullName();
            eID = user.getEID();
            reason = user.getReason();

            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/chat_applet","root","");
            PreparedStatement statement = con.prepareStatement("INSERT INTO REQCONFROOM VALUES(\"" + fullName + "\",\"" + eID + "\",\"" + reason + "\")");
            statement.execute();

            out = new ObjectOutputStream(response.getOutputStream());
            out.writeObject("success");
            out.flush();

        } catch (Exception e)  {
            e.printStackTrace();
            out = new ObjectOutputStream(response.getOutputStream());
            out.writeObject("fail");
            out.flush();
        }
    }

Wenn ich auf die Schaltfläche klicke, die den Code auf der Applet-Seite aufruft, wird folgende Fehlermeldung angezeigt:

Warum erhalte ich diesen Fehler? Ich habe gespült, als ich ausgegeben habe, ich habe die Verbindungen auch geschlossen, aber ich bekomme den Fehler. Irgendein Grund dafür?
