Connection refused exception

Question

I am getting this exception:

org.apache.http.conn.HttpHostConnectException: Connection to http://www.google.es refused

The code I am running is this one:

public class sdf {

static String url = "http://www.google.es";

public static void main(String[] args) {

    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(
                new DefaultHttpClient().execute(new HttpGet(url))
                        .getEntity().getContent()));
        String line;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
}

It doesn't matter what's the value of url, it won't work.

What am I doing wrong?

Did you have Manifest with right permission? This is an example of you have to do:

<manifest xlmns:android...>
 ...
      <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

Without this you won't be able to have internet connection
