Smack: Unable to send a message with a Chat created with “Chat chat = mgr.createChat(”winnenair“,listener);”

Question

MessageListener listener = new MessageListener(){
    @Override
    public void processMessage(Chat chat, Message message){
        println message.getBody()
    }
}
ConnectionConfiguration cfg = new ConnectionConfiguration("my-pc",5222);
cfg.setSASLAuthenticationEnabled(true);
XMPPConnection con = new XMPPConnection(cfg);
con.connect();
con.login("littlechild","secretpassword");
ChatManager mgr = con.getChatManager();
Chat chat = mgr.createChat("winnenair",listener);
chat.sendMessage("Hello!");
// con.disconnect();  

I am using this code to send a message to a user named " winnenair ".

My OpenFire Admin Console does show me (the code) and the user (Spark IM Client) as online. However, when I send a message from the code, it never appears in the IM Client. Both of them are on the same laptop.

Have I done something wrong?

Extra:
Both the users have been added to the roster

Answer 1

The problem is confined to this line:

Chat chat = mgr.createChat("winnenair",listener);  

The name " winnenair " needs to be " winnenair@my-pc ". One needs to append the domain to the username.
