public class Themail {

    public static void main(String[] args) {
        final String username="youremail@gmail.com";

        Properties prop=new Properties();
        prop.put("mail.smtp.auth", "true");
        prop.put("mail.smtp.host", "smtp.gmail.com");
        prop.put("mail.smtp.port", "587");
        prop.put("mail.smtp.starttls.enable", "true");

        Session session = Session.getDefaultInstance(prop,
      	new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(username, password);
          	}
    	});
      	try {
            String htmlBody = "<strong>This is an HTML Message</strong>";
            String textBody = "This is a Text Message.";
		    Message message = new MimeMessage(session);
		    message.setFrom(new InternetAddress("fromemail@gmail.com"));
            message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("toemail@gmail.com"));
	        message.setSubject("Testing Subject");
	        MailcapCommandMap mc = (MailcapCommandMap) CommandMap.getDefaultCommandMap();
	        mc.addMailcap("text/html;; x-java-content-handler=com.sun.mail.handlers.text_html");
	        mc.addMailcap("text/xml;; x-java-content-handler=com.sun.mail.handlers.text_xml");
	        mc.addMailcap("text/plain;; x-java-content-handler=com.sun.mail.handlers.text_plain");
	        mc.addMailcap("multipart/*;; x-java-content-handler=com.sun.mail.handlers.multipart_mixed");
	        mc.addMailcap("message/rfc822;; x-java-content-handler=com.sun.mail.handlers.message_rfc822");
	        CommandMap.setDefaultCommandMap(mc);
	        message.setText(htmlBody);
            message.setContent(textBody, "text/html");
        	Transport.send(message);

        	System.out.println("Done");

        } catch (MessagingException e) {
            e.printStackTrace();
