如何通过我的XPages代码向外部电子邮件ID发送电子邮件

import javax.mail.*;
import javax.mail.internet.*;

public class SendEmail {
   public static void main(String [] args) {    
      // 配置SMTP服务器和端口
      String host = "smtp.example.com";
      String port = "587";
      
      // 配置发件人邮箱和密码
      String senderEmail = "sender@example.com";
      String senderPassword = "password";
      
      // 配置收件人邮箱
      String recipientEmail = "recipient@example.com";
      
      // 配置邮件主题和内容
      String subject = "Test Email";
      String body = "This is a test email.";
      
      // 设置邮件属性
      java.util.Properties props = new java.util.Properties();
      props.put("mail.smtp.auth", "true");
      props.put("mail.smtp.starttls.enable", "true");
      props.put("mail.smtp.host", host);
      props.put("mail.smtp.port", port);
      
      // 创建会话对象
      Session session = Session.getInstance(props, new javax.mail.Authenticator() {
         protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(senderEmail, senderPassword);
         }
      });
      
      try {
         // 创建邮件对象
         Message message = new MimeMessage(session);
         message.setFrom(new InternetAddress(senderEmail));
         message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipientEmail));
         message.setSubject(subject);
         message.setText(body);
         
         // 发送邮件
         Transport.send(message);
         
         System.out.println("Email sent successfully.");
      } catch (MessagingException e) {
         e.printStackTrace();
      }
   }
}
