Could not connect to google talk service

i am using Smack 3.0.2. I wrote a small test class but could not connect to the google talk. following is the code piece:

import org.jivesoftware.smack.*;

import org.jivesoftware.smack.sasl.*;

import java.util.*;

public class test1 {

/** Creates a new instance of test1 */

public test1() {

}

public static void main(String[] args) {

try {

ConnectionConfiguration config = new ConnectionConfiguration(“talk.google.com”, 5222, “gmail.com”);

config.setSecurityMode(ConnectionConfiguration.SecurityMode.required);

XMPPConnection conn = new XMPPConnection(config);

conn.connect();

} catch (Exception ex) {

ex.printStackTrace();

}

}

}

now the exception information

XMPPError connecting to talk.google.com:5222.: remote-server-error(502) XMPPError connecting to talk.google.com:5222.

Leave off config.setSecurityMode(ConnectionConfiguration.SecurityMode.required). If you look just a couple of threads down on the first page of the forum there is another google talk thread already where I posted a working example.
