(a) Error sending message "service-unavailable (503)" at login ()

Question

I am trying to implement a simple jabber messenger on Android using the asmack library. Here is the code:

public boolean login()
{
    if (connection != null && connection.isConnected())
    {
        Log.i("XMPP", connection.getHost());
        try 
        {
            connection.login(USERNAME, PASSWORD);
        } 
        catch (XMPPException e) 
        {
            e.printStackTrace();
            return false;
        }
        return true;
    }
    return false;
}

I get an exception after connection.login () (the connection looks great):

What could be a mistake?

Answer 2

:

ConnectionConfiguration connConfig = new ConnectionConfiguration(host,port,host);
connection = new XMPPConnection(connConfig);
connConfig.setSASLAuthenticationEnabled(true); 
connection.connect();
connection.login(userID, password);

Android Asmack, URL:

https://code.google.com/p/asmack/downloads/detail?name=asmack-2010.05.07.jar

.

connection.login("username@ejabberdServerIP",password)

, connection.login( " ", );
