Set the following tags. It will work.

props.put("mail.smtp.user","username"); 
props.put("mail.smtp.host", "smtp.gmail.com"); 
props.put("mail.smtp.port", "25"); 
props.put("mail.debug", "true"); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.smtp.starttls.enable","true"); 
props.put("mail.smtp.EnableSSL.enable","true");

props.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");   
props.setProperty("mail.smtp.socketFactory.fallback", "false");   
props.setProperty("mail.smtp.port", "465");   
props.setProperty("mail.smtp.socketFactory.port", "465");
