public void send(String uniqueId, Date reviewDateTime) throws Exception

{

String from = "123@456.com";

String to = "456@456.com";

StringBuffer sb = new StringBuffer();

StringBuffer buffer = null;

Session session = Session.getDefaultInstance(prop, null);

Message message = new MimeMessage(session);



try {

prop.put("mail.smtp.host", "192.168.112.111");

prop.put("mail.smtp.port", "25");



// Define message

message.setFrom(new InternetAddress(from));

message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false));

message.setRecipients(Message.RecipientType.CC, InternetAddress.parse("123@456.com,456@456.com,789@456.com"));

message.setSubject("This is the subject of the Meeting Request");

message.setHeader("X-Mailer", "iQuest-Mailer");



// Create the message part

MimeBodyPart messageBodyPart = new MimeBodyPart();
