I need some example. It’s my first project with XMPP server. I need to create service which sendPresent(get) sendData(or message) and get some data. I need help. Thank!

This is my code :

XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
         .setUsernameAndPassword(mSettings.getXmppUserName(), mSettings.getXmppPassword())
         .setServiceName(mSettings.getXmmpDomain())
         .setHost("host")
         .setKeystorePath(mSettings.getXmppPath())
                 //.setPort(mSettings.getXmppPort())
         .setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled)
         .build(); JID = mSettings.getXmppUserName() + "@" + mSettings.getXmmpDomain(); try {
     conn = new XMPPTCPConnection(config);
     conn.connect();
     logger.error("Connect.......+++++++++++++");
     conn.login();
     logger.error("Connect.......+++++++++++++");
     Presence presence = new Presence(Presence.Type.unavailable);
     presence.setStatus("Online " + JID);      conn.sendStanza(presence);
     logger.error("Online " + JID);
     StanzaFilter myFilter = new StanzaFilter() {
         public boolean accept(Stanza stanza) {
             return true;
         }
     };
