    {
        pw.instantiateReadObjects();
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    }

    try
    {
        String smtpHost=pw.getHostNameMail();
        String smtpPort=pw.getPortNumber();
        final String fromAddress=pw.getEmailSource();
        final String password=pw.getEmailPassword();

        String SSL_FACTORY="javax.net.ssl.SSLSocketFactory";


        Properties props=new Properties();

        props.put("mail.smtp.host", smtpHost);
        props.put("mail.smtp.auth", "true");
        props.put("mail.debug","true");
        props.put("mail.smtp.port", smtpPort);
        props.put("mail.smtp.socketFactory.port",smtpPort);
        props.put("mail.smtp.socketFactory.class",SSL_FACTORY);
        props.put("mail.smtp.starttls.enable","ture");
        props.put("mail.smtp.socketFactory.fallback","false");

        Session ses=Session.getDefaultInstance(props,new javax.mail.Authenticator()
        {
            protected PasswordAuthentication getPasswordAuthentication(){
                return new PasswordAuthentication(fromAddress,password);
            }
        });

        ses.setDebug(true);
        Message msg=new MimeMessage(ses);

        InternetAddress addressFrom=new InternetAddress(fromAddress);
        msg.setFrom(addressFrom);

        InternetAddress addressTo=new InternetAddress(emailId);
        msg.setRecipient(Message.RecipientType.TO, addressTo);

        msg.setSubject(subject);

         StringBuffer sb = new StringBuffer();
         System.out.println(mailBody);
            StringBuffer buffer = sb.append("BEGIN:VCALENDAR\n" +

    }

Try simply to add the message body first like this:

multipart.addBodyPart(messageBody);
multipart.addBodyPart(messageCalendar);

Instead of this:

multipart.addBodyPart(messageCalendar);
multipart.addBodyPart(messageBody);
