import org.jivesoftware.smack.SmackException; 
import org.jivesoftware.smack.XMPPException; 
import org.jivesoftware.smack.tcp.XMPPTCPConnection; 
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration; 


public class Tests 
{ 

    public static void main(String[] args) throws SmackException,  IOException, XMPPException 
    { 

     XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder() 
     .setHost("127.0.0.1") 
     .setPort(5222) 
     .build(); 
     AbstractXMPPConnection conn1 = new XMPPTCPConnection(config); 

     try 
     { 
      conn1.connect(); 
     } 
     catch (XMPPException e) 
     { 
      e.printStackTrace();

Я использовал чмок в Maven проекта и здесь зависимостей, которые я определил.

<dependency> 
     <groupId>xpp3</groupId> 
     <artifactId>xpp3</artifactId> 
     <version>1.1.4c</version> 
    </dependency> 
    <dependency> 
     <groupId>xpp3</groupId> 
     <artifactId>xpp3_min</artifactId> 
     <version>1.1.4c</version> 
    </dependency> 
    <dependency> 
     <groupId>xpp3</groupId> 
     <artifactId>xpp3_xpath</artifactId> 
     <version>1.1.4c</version> 
    </dependency> 

    <dependency> 
     <groupId>org.igniterealtime.smack</groupId> 
     <artifactId>smack-tcp</artifactId> 
     <version>4.0.6</version> 
    </dependency> 
    <dependency> 
     <groupId>org.igniterealtime.smack</groupId> 
     <artifactId>smack-extensions</artifactId> 
     <version>4.0.6</version> 
    </dependency> 

и в коде:

ConnectionConfiguration config = new ConnectionConfiguration("IM_DOMAIN", 5222); 
    config.setDebuggerEnabled(false); 
    config.setSecurityMode(SecurityMode.disabled); 
    XMPPTCPConnection con = new XMPPTCPConnection(config); 

    try { 

     con.connect(); 
     con.login("USERNAME", "PASSWORD"); 

     Message msg = new Message("RECIPIENT_JID"); 
     msg.setBody("message"); 
     msg.setType(Type.chat); 
     con.sendPacket(msg); 

    } catch (SmackException | XMPPException | IOException | InterruptedException e) { 
     throw e; 

    } finally { 
     if (null != con) { 
      try { 
       con.disconnect(); 
      } catch (NotConnectedException e) { 

      } 

     } 
    }
