Xmpp Smack Chat not able to send and receiving message - xmpp

Question

I have tried to establish chat connection between two users using xmpp and OpenFire. But i am not able to send and receive message. I have pasted my code below for reference. Any help will be very helpful.
I established a connection with Smack by
XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
config.setUsernameAndPassword("admin", "admin");
config.setServiceName("172.21.4.199");
config.setHost("172.21.4.199");
config.setPort(5222);
config.setDebuggerEnabled(true);
config.setConnectTimeout(50000);
XMPPTCPConnection connection = new XMPPTCPConnection(config.build());
XMPPTCPConnection.setUseStreamManagementResumptiodDefault(true);
XMPPTCPConnection.setUseStreamManagementDefault(true);
try {
connection.setPacketReplyTimeout(50000);
connection.connect();
Log.d(TAG, "SetupDefaults -- Connected");
} catch (Exception e) {
e.printStackTrace();
Log.d(TAG, "SetupDefaults -- Connection failed exc: "+e);
}
and its gets succesfully connected. And i try to send a chat by using
ChatManager chatManager = ChatManager.getInstanceFor(connection);
Chat chat = chatManager.createChat("user2#server.local", new ChatMessageListener() {
#Override
public void processMessage(Chat chat, Message message) {
System.out.println("processMessage -- Sent message: " + message);
}
});
try {
chat.sendMessage("Hai.. Lets we chat!");
}catch (Exception e){
Log.d(TAG, "sendChat Exc: "+e.toString());
}
But i couldn't find that processMessage gets triggered. Because that S.O.P doesn't gets triggered. But i gets
SMACK: SENT (0): Hai.. Lets we chat!
SMACK: RECV (0): Hai.. Lets we chat!
in my console while sending a chat.
Simillarly i use,
PacketListener packetListener = new PacketListener() {
#Override
public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
Message message = (Message)packet;
String from = message.getFrom();
String body = message.getBody();
System.out.println("Message from: " + from + " " + body);
}
};
connection.addPacketListener(packetListener, filter);
to receive the chat. But processPacket also doesn't gets triggered.

PacketListner it's something much more general to handle stanzas, it's not what you really need. You just need a ChatMessageListner
ChatManager chatManager;
chatManager = ChatManager.getInstanceFor(connection);
chatManager.addChatListener(
**new ChatManagerListener() {
#Override
public void chatCreated(Chat chat, boolean createdLocally)
{
if (!createdLocally)
{
chat.addMessageListener(new IncomingMessageListener());;
}
}
})**;
Basic implementation:
class IncomingMessageListener implements ChatMessageListener {
#Override
public void processMessage(Chat arg0, Message message) {
String from = message.getFrom();
String body = message.getBody();
if (body != null)
{
System.out.println(String.format("============ Received message '%1$s' from %2$s\n============", body, from));
guiUpdate.displayMessage(body); /* custom method */
}
else
{
System.out.println("SYSTEM: ping");
}
}
