        //MsnMessenger support all protocols by default
        //messenger.setSupportedProtocol(new MsnProtocol { MsnProtocol.MSNP8 });

        //default init status is online,
        //messenger.getOwner().setInitStatus(MsnUserStatus.BUSY);

        //log incoming message
        messenger.setLogIncoming(true);

        //log outgoing message
        messenger.setLogOutgoing(true);

        initMessenger(messenger);
        messenger.login();
    }

    public static void main(String args) throws Exception {
        if (args.length != 3) {
            System.out.println("Usage: java messengerClassName email password");
            return;
        }
        BasicMessenger messenger = (BasicMessenger) Class.forName(args)
                .newInstance();
        messenger.setEmail(args);
        messenger.setPassword(args);
        messenger.start();
    }
}

Instead of:

 BasicMessenger messenger = (BasicMessenger) Class.forName(args[0])  .newInstance(); messenger.setEmail(args[1]); messenger.setPassword(args[2]);

just do this:

MsnMessengerFactory.createMsnMessenger(email,password);

@chnd, just pass three parameters. the class name BasicMessenger, username and password. it should work.
