Problems with reading information sent from a servlet to an applet

Question

Ihave just created an applet and servlet. i want the servlet to send some data back to the applet so i can read it and just check to see whether the servlet has done the required job.
here is part of the applet and servlet code.
applet:
url = "http://localhost:8080/servlet/Option1Servlet?Firstname="+firstname.getText()
               +"&Lastname="+lastname.getText()+"&Staffstudentid="+staffstudentid.getText()
               +"&Position="+position.getText()+"&Email="+email.getText();
          Vector servletInfo = new Vector();
          ObjectInputStream inputFromServlet;
          try{
               String inputLine;
               System.out.println(url);
               URL urlocation = new URL(url);
               URLConnection uc = urlocation.openConnection();
               BufferedReader in = new BufferedReader(new InputStreamReader (uc.getInputStream()));
                    while((inputLine=in.readLine()) != null) {
                         servletInfo.add(inputLine);
               System.out.println("recieved info from servlet about ot process!");
               inputFromServlet = new ObjectInputStream(uc.getInputStream(checking));
               checking = (int)inputFromServlet.readInt();
               System.out.println(checking);
               in.close();
          catch(java.io.IOException ex) {ex.printStackTrace();}
          if (checking == 0) {
          Regcomplete f5 = new Regcomplete();
          f5.setSize(500,400);
               this.setVisible(false);
          f5.setVisible(true);
          else if (checking == 1) {
               firstname.setText("ERROR HAS OCCURED! CLICK CANCEL");
               lastname.setText("");
               staffstudentid.setText("");
               position.setText("");
               email.setText("");
servlet:
public void sendCheckingValue(HttpServletResponse res, int checking) {
          ObjectOutputStream outputToApplet;
          try {
               outputToApplet = new ObjectOutputStream(res.getOutputStream());
               System.out.println("Sending int to applet ... ");
               outputToApplet.writeInt(checking);
               outputToApplet.flush();
               outputToApplet.close();
               System.out.println("Data transmission complete.");
               System.out.println("Checking value sent = " + checking);
          catch (IOException e) { e.printStackTrace(); }
i get this exception when i run the code: this exception is thrown in the applet when it attempts to read the input data that has been sent:
C:\My Documents\logina>appletviewer Login.html
http://localhost:8080/servlet/Option1Servlet?Firstname=nnnnnnnnn&Lastname=nn&Sta
