You can use the following to check if you are online and that a specific URL is reachable.
import java.net.*;
import java.io.*;
public class URLChecker
     public static boolean checkURL(String s)
          boolean reachable = true;
          try
               URL url = new URL(s);
               URLConnection conn = url.openConnection();
               conn.setRequestProperty("User-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)");
               BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
               rd.close();
          catch (IOException ioex)
               reachable = false;
          return reachable;
}
