I'm trying to implement a simple jabber messenger on Android using asmack library. Here's 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;
}

Exception I get after connection.login() (connection looks fine):

service-unavailable(503)

What could be the mistake?

  • Hum could you please add more details? what server are you trying to connect to, are you sure to specify the right port/domain/host? service unavailable generally means that it can' be reached or that you specified wrong information. – Guillaume Jul 16 '11 at 11:02

It's working finally for me by this way :

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

I have used Android using Asmack library which I have downloaded from below URL:

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

Be careful about the userID.

Instead of using 

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

it's work for me only if I use connection.login("username",password);

Good luck...

Asmack is able to establish a new connection to the server, but it falls into Non-SASL mode for some reason ( The call of NonSASLAuthentication.authenticate(NonSASLAuthentication.java:77) ). I think that's what the server is trying to tell you with the "service-unavailable(503)" response, is that it does not support Non-SASL authentication.

Try to debug why smack does not try SASL authentication.

Note: The lines in the smack source viewer are a bit off because off different versions and the patches from asmack.
