if(buttonObj == searchButton)
     try
          String name = nameField.getText();
          URL url = new URL("http://www.kingsofchaos.com/battlefield.php?jump=&search_type=s&search=" + name);
          URLConnection connection = url.openConnection();
          BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
          // this isnt in my actual program but is just to show the output.
                line = in.readLine();               
          for(int i = 0; i < 20; i++)
               System.out.println(line);
     catch(Exception e)
          System.out.print(e);
}ok well thats the code the gets the urls information.
so when i keep the url the way it is i just get null, null, null, ect
however when i change the url to:
URL url = new URL("http://www.yahoo.com");i actually get some output besides null. any help is appreciated.
