I am developing a Java App to chat with devices in XMPP.
Given the logs I am able to send messages but I can't receive them
Here is my code
XMPPListener.java
package messaging;
import java.io.IOException;
import org.jivesoftware.smack.AbstractXMPPConnection;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.ConnectionConfiguration.SecurityMode;
import org.jivesoftware.smack.SmackException;
import org.jivesoftware.smack.SmackException.NotConnectedException;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.chat.Chat;
import org.jivesoftware.smack.chat.ChatManager;
import org.jivesoftware.smack.chat.ChatManagerListener;
import org.jivesoftware.smack.chat.ChatMessageListener;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;
public class XMPPListener implements MessageListener {
AbstractXMPPConnection connection;
public XMPPListener(String host, int port, String serviceName){
XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder().
setHost(host)
.setServiceName(serviceName)
.setSecurityMode(SecurityMode.ifpossible)
.setPort(port)
.setDebuggerEnabled(true)
.build();
this.connection = new XMPPTCPConnection(config);
}
public void connect() {
try {
this.connection.connect();
} catch (SmackException | IOException | XMPPException e) {
e.printStackTrace();
}
}
public void login(String userName, String password) throws XMPPException {
try {
this.connection.login(userName, password);
} catch (SmackException | IOException e) {
e.printStackTrace();
}
}
public void sendMessage(String message, String to) throws XMPPException {
Chat chat = ChatManager.getInstanceFor(connection).createChat(to);
try {
chat.sendMessage(message);
} catch (NotConnectedException e) {
e.printStackTrace();
}
}
public void listenChat(String name){
ChatManager manager = ChatManager.getInstanceFor(this.connection);
manager.addChatListener(new ChatManagerListener() {
@Override
public void chatCreated(Chat chat, boolean createdLocally) {
System.out.println("Created chat");
chat.addMessageListener(new ChatMessageListener() {
@Override
public void processMessage(Chat chat, Message message) {
System.out.println(message.getBody());
}
});
}
});
}
public void disconnect() {
connection.disconnect();
}
@Override
public void processMessage(Message message) {
System.out.println("Received something: " + message.getBody());
}
}
Main.java
XMPPListener xmppListener = new XMPPListener("ajabber.me",5222,"ajabber.me");
try {
xmppListener.connect();
xmppListener.login(user, password);
xmppListener.listenChat(to);
while(true){
xmppListener.sendMessage("Spack me spack me, Ho !", to);
Thread.sleep(10000);
}
} catch (XMPPException e2) {
e2.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
In this code I connect to a random server i found here : list of servers. Then I try to send some messages I have the folowing logs

Given those logs, I guess the messages are sent and the chat is also created but it seems that I never receive the messages. Could you guys help me solve this problem ?
I run java 1.8 and Smack 4.7
EDIT
I have tried using Spark : I manage to talk with my application (in a Spark client), I also have edited my code as a new version
Here is the proof with a wonderful screenshot
However I still cannot retrieve my messages : I see them in the logs, but the method in the chat listener is not called

LAST EDIT
My code is working with the one above, a special thanks to MrKp
