hello,
i used this code for jabber client

import java.util.*;
import java.io.*;
import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Message;

public class chat implements MessageListener{

XMPPConnection connection;

public void login(String userName, String password) throws XMPPException
{
//////////ConnectionConfiguration config = new ConnectionConfiguration("im.server.here",5222, "Work");
connection = new XMPPConnection("jabber.org");

connection.connect();
connection.login(userName, password);
}

public void sendMessage(String message, String to) throws XMPPException
{
Chat chat = connection.getChatManager().createChat(to, this);
chat.sendMessage(message);

}


public void displayBuddyList()
{
Roster roster = connection.getRoster();
Collection<RosterEntry> entries = roster.getEntries();

System.out.println("\n\n" + entries.size() + " buddy(ies):");
for(RosterEntry r:entries)
{
System.out.println(r.getUser());
}
}

public void disconnect()
{
connection.disconnect();
}

public void processMessage(Chat chat, Message message)
{
if(message.getType() == Message.Type.chat)
System.out.println(chat.getParticipant() + " says: " + message.getBody());
}

public static void main(String args[]) throws XMPPException, IOException
{
// declare variables
chat c = new chat();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String msg;


// turn on the enhanced debugger
XMPPConnection.DEBUG_ENABLED = true;


// Enter your login information here
c.login("hassan786@jabber.org", "bcsf08m018");

c.displayBuddyList();

System.out.println("-----");

System.out.println("Who do you want to talk to? - Type contacts full email address:");
String talkTo = br.readLine();

System.out.println("-----");
System.out.println("All messages will be sent to " + talkTo);
System.out.println("Enter your message in the console:");
System.out.println("-----\n");

while( !(msg=br.readLine()).equals("bye"))
{
c.sendMessage(msg, talkTo);
}

c.disconnect();
System.exit(0);
}
}

Problem is that

i have made account on jabber.org now if i run the this java programme so if i put my own username and password as well as on console when programme asked that to which user you wanted to connect if i put my own username again than this programme send message and also show on console the recieve message .But if on console i put some other jabber username to which i send message and this user is also online (means run this application on another laptop) but he never recieve the message on his console.

Also explain what parameters i put for jabber account there(new ConnectionConfiguration("im.server.here",5222, "Work")

reply to " swaqpoli " post

presence = roster.getPresence(r.getUser());
after above line try with presense.getStatus();
the same problem i have faced when i am running it on local
but when i run it on our site it runs perfectly. once u try with uploding application into your real website

Following is the used java class. It is able to connect but not able to login. I also tried setting XMPPConnection.DEBUG_ENABLED = true and config.setSASLAuthenticationEnabled(false), but in vain.

public class  ConnectionToLocalServer {
    private static String username =  "admin@localhost"; 
    private static String password =  "genespring123"; 
    ConnectionConfiguration connConfig;
    XMPPConnection connection;
 
    public ConnectionToLocalServer() throws  XMPPException {  
    	ConnectionConfiguration config = new ConnectionConfiguration("localhost",5222);        
        connection = new XMPPConnection(config);
        connection.connect();
        System.out.println("CONNECTED..");
        connection.login(username, password);
        System.out.println("LOGED IN..");
    }
 
    ...
   }
}

pamashree? do you already have an answer on this?
