public void sendMail(String from, String to, String cc, String bcc, String subject, String body) 
	{	
		Properties props = new Properties();
		props.setProperty("mail.transport.protocol", "smtp");
		props.put("mail.smtp.host", SMTP_HOST_NAME);
		props.put("mail.smtp.auth", "true");
		props.put("mail.smtp.port", "465");
		
		Authenticator auth = new SMTPAuthenticator();
		Session mailSession = Session.getDefaultInstance(props, auth);
		mailSession.setDebug(true);
		Transport transport;
		try
		{
			transport = mailSession.getTransport();
			MimeMessage message = new MimeMessage(mailSession);
			message.setSubject(subject);
			message.setText(body);
			message.addRecipient(Message.RecipientType.TO,
