send and receiving message using smack API
Solution 1
I had a similar problem, after following the tutorial here (http://www.javacodegeeks.com/2010/09/xmpp-im-with-smack-for-java.html) and this is what I found:
When you create the chat, you chat the user you want to connect to (eg in my case "user1@gbd038"). This works fine if user1 is using a GUI client such as Spark (which presumably has built-in support and/or error handling for this), and user1 will receive the message. This process attaches the messageListener to a chat now associated with "user1@gbd038". However, when I reply from Spark as user1, the chat that smack receives is actually coming through complete with the location tag, eg:
Received message 'hi' from user1@gbd038/Spark 2.6.3
So it creates a new chat that the application is not listening for (and therefore your application will not receive / print out). I have found two ways to solve this problem:
-
use the location tag when starting the conversation (although this doesn't seem very scalable or robust):
xmppManager.sendMessage("Hello mate", "user1@gbd038/Spark 2.6.3");
-
as Robin suggested, use a ChatManagerListener (which will create a new chat when receiving the reply from user1, which can be forwarded to the messageListener):
chatManager = connection.getChatManager(); messageListener = new MyMessageListener(); chatManagerListener = new ChatManagerListener() { @Override public void chatCreated(Chat chat, boolean createdLocally) { chat.addMessageListener(messageListener); } }; chatManager.addChatListener(chatManagerListener);
Hope that helps someone in the same position!
Solution 2
You are creating a chat and sending a chat message from both ends but not listening for a chat from either. Use a ChatManagerListener to listen for incoming chats from other clients.
Solution 3
Use below code for sending and receiving message
@Override
public void processMessage(Chat chat, Message message) {
// Print out any messages we get back to standard out.
System.out.println("Received message: " + message);
}
});
chat.sendMessage("How are you dear !!");
System.out.println(" Send Message succesfully");

I have setup my open fire(jabber server) on local machine with two user testuser1 and testuser2 .using Spark client both users perform chat without any issue,it's nice.
openfire IP -192.168.1.65
I want to use smack API(3.3.0) for send and receiving message. i have write sender side code to send message(with testuser1) and tested with Spark client(with testuser2) message received on testuser2 side,but when i try with java code to receive sender message ,i am not able to receive those publish messages.
Sender.java
import org.jivesoftware.smack.Chat; import org.jivesoftware.smack.XMPPConnection; import org.jivesoftware.smack.XMPPException; import org.jivesoftware.smack.packet.Message; import org.jivesoftware.smack.MessageListener; public class Sender { public static void main(String a[]) throws XMPPException, InterruptedException { XMPPConnection connection = new XMPPConnection("192.168.1.65"); System.out.println(connection); connection.connect(); connection.login("testuser1", "test123"); Chat chat = connection.getChatManager().createChat("testuser2@sameek", new MessageListener() { public void processMessage(Chat chat, Message message) { // Print out any messages we get back to standard out. System.out.println("Received message: " + message); } }); chat.sendMessage("Howdy test1!"); while (true) { Thread.sleep(50); } } }
Receiver.java
import org.jivesoftware.smack.Chat; import org.jivesoftware.smack.XMPPConnection; import org.jivesoftware.smack.XMPPException; import org.jivesoftware.smack.packet.Message; import org.jivesoftware.smack.MessageListener; public class Receiver { public static void main(String a[]) throws XMPPException,, InterruptedException { XMPPConnection connection = new XMPPConnection("192.168.1.65"); System.out.println(connection); connection.connect(); connection.login("testuser2", "test123"); Chat chat = connection.getChatManager().createChat("testuser1@sameek", new MessageListener() { public void processMessage(Chat chat, Message message) { // Print out any messages we get back to standard out. System.out.println("Received message: " + message); } }); chat.sendMessage("Howdy test2!"); while (true) { Thread.sleep(50); } } }
please help me and suggest if i am following wrong approach.
Thanks
