Re: i am trying to connect to openfire using this code

you should set the username and password like this (smack 4.1.0):

configuration = XMPPTCPConnectionConfiguration.builder()

  .setUsernameAndPassword("username", "password")

.setServiceName("your.server")

.setHost("your.server.ip")

.setConnectTimeout(3000)

.setSendPresence(false)

.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)

.build();

connection = new XMPPTCPConnection(connectionConfig);

connection.connect();
