how to connect to openfire server using smack api 4.1.0

i am trying to connect to my openfire server by this code

String DOMAIN = "my server ip";
AbstractXMPPConnection connection;
try{
 XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();    config.setSecurityMode(SecurityMode.disabled);    config.setUsernameAndPassword("admin@"+DOMAIN, "my password");    config.setServiceName(DOMAIN);    config.setHost(DOMAIN);    config.setPort(5222);    config.setDebuggerEnabled(true);   connection = new XMPPTCPConnection(config.build());   connection.setPacketReplyTimeout(10000);   connection.addConnectionListener(this);     connection.connect();     AccountManager AM = AccountManager.getInstance(connection);     AM.createAccount("userName", "password");     connection.disconnect();     System.out.println(":)");    }  catch(Exception e){  System.out.println(":(");    }

my code is in try catch statement but still after running this code nothing gets printed and i get this errors:
