I’m runnining into an issue with Smack 4.0.0-SNAPSHOT:
//////////////////////////////////////////////////////////////////////////////// ////////////////////////////////////////////////////////
My code:
public class Test {
private static final Logger logger = LoggerFactory.getLogger(Test.class.getName());
public static void main(String[] args){
//XMPPService is a wrapper to obtain a XMPPConnection
XMPPService xmpp = new XMPPService(“USERNAME@HOSTNAME”, “PASSWORD”);
XMPPConnection connection;
try {
connection = xmpp.connect();
} catch (XMPPException e) {
logger.error(“Could not connect: XMPPException”, e);
return;
} catch (SmackException e) {
logger.error(“Could not connect: SmackException”, e);
return;
} catch (IOException e) {
logger.error(“Could not connect: IOException”, e);
return;
}
assert connection.isSecureConnection();
logger.debug(“connection established and authentication successfull!”);
MultiUserChat muc = new MultiUserChat(connection, “ROOMNAME@MUCSERVICE”);
muc.addMessageListener(new ConsumerMUCMessageListener());
try {
muc.join(“DirkJavaTest”);
} catch (NoResponseException e) {
logger.error(“Could not join conversation: IOException”, e);
} catch (XMPPErrorException e) {
logger.error(“Could not join conversation: IOException”, e);
} catch (NotConnectedException e) {
logger.error(“Could not join conversation: IOException”, e);
}
logger.debug(“joined conversation!”);
try {
muc.sendMessage(“Hello world!”);
} catch (NotConnectedException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
}
}
private static class ConsumerMUCMessageListener implements PacketListener {
private int messageCount=0;
public void processPacket(Packet packet) {
if (packet instanceof Message) {
Message msg = (Message)packet;
logger.info(“Received message number : " + (messageCount++)+”: "+msg.getBody());
}
}
@SuppressWarnings(“unused”)
public int getMessageCount() {
return messageCount;
}
}
}

The output:

My question:
Why would “muc.join(NICKNAME)” throw a NoResponseException? It appears the user has successfully joined the room, when I look at the server. Also, it takes ± 5seconds before the “join” call returns, but the user was in the room immediatly at the beginning. Am I doing something wrong?
