本文介绍了一种使用Java实现基于XMPP协议的即时通讯功能的方法。文中详细展示了如何通过XMPPConnection类完成服务器连接及登录验证，并发送消息给指定接收者。

public class SendMessage{

private XMPPConnection con;
private ChatManager chatmanager;

public XMPPConnection login(String messageProducer, String messageProducerPassword) {
        ConnectionConfiguration config = new ConnectionConfiguration(this.serverDomain,
                this.serverPort);
        XMPPConnection con = new XMPPConnection(config);
        try {
            con.connect();
        } catch (XMPPException e) {
            throw new RuntimeException("Connect xmpp server", e);
        }
        try {
            con.login(this.messageProducer, this.messageProducerPassword);
        } catch (XMPPException e) {
            throw new RuntimeException("login failed: " + e.getMessage() + " with "
                    + messageProducer + ":" + messageProducerPassword);
        }
        return con;

}

    private void sendMessage(String to, String message) {
        try {
            Chat newChat = chatmanager.createChat(to, new MessageListener() {
                public void processMessage(Chat chat, Message message) {
                }
            });
            newChat.sendMessage(message);
        } catch (XMPPException e) {
            log.error("Got error while sending message to " + to.getUsername(), e);
        }
    }

    private void layout() {
        if (con != null && con.isConnected()) {
            con.disconnect();
        }
    }

}
