HTTPConnection in mobiles

[feda alshahwan]

I created a code to set up RESTful web server and I tried using HTTpConnection to extract the HTTP headers but unfortunately I got Casting Exception error?
Does anybody know the reason ?

   public void run(){
            ServerSocketConnection scn =null;
            try{
                scn=(ServerSocketConnection) Connector.open("socket://:30000");

            }catch (IOException ex){
                ex.printStackTrace();
        }
            while (true)
            {
                try{
                    form.append("Waiting for Client Request........");
                    HttpConnection httpc;
                    httpc= (HttpConnection) scn.acceptAndOpen();
                    form.append("Request Accepted on host address :"+scn.getLocalAddress()+" And on Port number:" +scn.getLocalPort());
                    RequestHandler RH=new RequestHandler (httpc);

                }catch (IOException ex){
                    ex.printStackTrace();
                }
            }
    }
        public class RequestHandler extends Thread{
            HttpConnection httpc;
            String requestMethod;
            RequestHandler (HttpConnection httpc){
                httpc=this.httpc;
                start();
            }
            public void run(){
                InputStream is = null;
            try {
                is = httpc.openInputStream();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
                OutputStream os = null;
            try {
                os = httpc.openOutputStream();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
                try{
                    httpc.getRequestMethod();
                }catch (Exception e){
                    e.printStackTrace();
                }
            try {
                os.write("WelCome Client".getBytes());
            } catch (IOException ex) {
                ex.printStackTrace();
            }
            try {
                os.flush();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
            try {
                os.close();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
            }
        }
