如何从Gmail Ical4j API发送会议邀请

Question

我正在使用 Ical4j API 从我的 gmail id 发送会议邀请，但如何设置

VEvent meeting = new VEvent(startDt, dur, subject);

VEvent邮件 API 类的对象

    Message message = new MimeMessage(session);
    message.setFrom(new InternetAddress("[e-mail]"));
    message.setRecipients(Message.RecipientType.TO,    InternetAddress.parse("[e-mail]"));
    message.setSubject("Testing Subject");
    message.setText("Dear Mail Crawler," + "nn No spam to my email, please!");
    Transport.send(message);

我正在尝试这样的事情

message.setContent(meeting, "MyMeeting");

但它的投掷例外。知道我该怎么做吗？

这是一个解决方案

             try {
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress("[e-mail]"));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress("[e-mail]"));
        message.setSubject("Hello iCal4j Meeting Invitation");
        // create the message part
        MimeBodyPart messageBodyPart = new MimeBodyPart();
        // fill message
        messageBodyPart.setText("Hi Sir, Please see the demo example to send meeting invitaiton from iCal4j API.");
        Multipart multipart = new MimeMultipart();
        multipart.addBodyPart(messageBodyPart);
        // Part two is attachment
        messageBodyPart = new MimeBodyPart();
        DataSource source = new FileDataSource(calFile);
        messageBodyPart.setDataHandler(new DataHandler(source));
        messageBodyPart.setFileName(calFile);
        multipart.addBodyPart(messageBodyPart);
        // Put parts in message
        message.setContent(multipart);
        Transport.send(message);
    //  System.out.println(meeting);
    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }
