Ho joely.

Here u have an example function that obtain content from an URL page:

    public static StringBuffer getURLContent (String url) {
        StringBuffer sb = new StringBuffer ();
        URL URLcontent = new URL(url);
        URLConnection conn = null;
        BufferedReader data = null;

        try {
            conn = URLcontent.openConnection();
            conn.connect();
            data = new BufferedReader (
                       new InputStreamReader (
                           conn.getInputStream ()));
                               
        }
        catch (IOException e) {
            System.out.println("Problems opening URL");
        }

        boolean test = true;
        while (test)
        {
            String str;
            try {
                str = new String (data.readLine ());
            }
            catch (Throwable e) { str = null; }
            if (str != null)
            {
                sb.append (str);
                sb.append ('\n');
                str = null;
            }
            else { test = false; }
        }
        return sb;
    }

hai joely,
  Check  whether u have give correct url,
  ie. in server side u  use these function to get url,
 URL url=new URL(req.getScheme()+"://"+req.getServerName()+":"+req.getServerPort()+"/file path");
