我在 Lotus Notes 中发送会议邀请时遇到了一些问题。我正在尝试以接受/拒绝功能格式查看，但它只是作为添加到日历功能中出现。所以如果有人可以帮助我解决这个问题，那就太好了.这是我的代码
Properties props = new Properties();
props.put("mail.smtp.host", SMTP_HOST_NAME);
props.put("mail.smtp.auth", "false");
Authenticator auth = new SMTPAuthenticator();
Session session = Session.getInstance(props, auth);
session.setDebug(debug);
MimeMessage msg = new MimeMessage(session);
msg.addHeaderLine("method=REQUEST");
msg.addHeaderLine("charset=UTF-8");
msg.addHeaderLine("component=VEVENT");
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
if (!(recipients == null)) {
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
log.debug("setting to recipients");
msg.setRecipients(Message.RecipientType.TO, addressTo);
}
if (!(recipientCC == null)) {
InternetAddress[] addressCC = new InternetAddress[recipientCC.length];
for (int j = 0; j < recipientCC.length; j++) {
addressCC[j] = new InternetAddress(recipientCC[j]);
}
log.debug("setting cc recipients");
msg.setRecipients(Message.RecipientType.CC, addressCC);
}
msg.setSubject(subject);
