I have written the code for gtalk chat client using Smack API .

This code displays a frame which contains 2 textarea 1 for sending message and other which contains received and sent messages.

My code sends the message to the particular email and it also shows on the 2nd textarea but when the message is received from the other person i can not display on the 2nd textarea .

Note that I know nothing about the Smack API, but I do wonder how you will be able to process messages when your method for this looks like this:

   public void processMessage(Chat chat, Message msg) {
        // ???? is something supposed to go here ????
   }

I have to ask myself if this is in fact your code or if it is borrowed code.

Best of luck.

thanks for the reply

basically that function was for testing stuff

This is the listener set which will process messages

PacketFilter filter= new AndFilter(new PacketTypeFilter(Message.class),new FromContainsFilter(email));

           PacketListener myListener = new PacketListener() {
                public void processPacket(Packet packet) {
                    if (packet instanceof Message) {
                        Message msg = (Message) packet;
                        // Process message
                        String temp = msg.getFrom();
                        String emailid = temp.substring(0,temp.lastIndexOf("/"));
                        String mess=msg.getBody();
                        System.out.println(emailid+" "+mess);
                        jTextPane1.append(emailid+" "+mess);
                    }
                }
            };
            connection.addPacketListener(myListener, filter);

thanks
