Answer 1

if you click on UnknownHostException: smtp.gmail.com, try ping smtp.gmail.com and make sure you have an answer (access to it). Often your connection may be blocked by your firewall or proxy server. Otherwise, you need javaee.jar and mail.jar in your classpath.

Please try these mail properties. Check the mail you must send successfully.

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