title: Transport.send(message) not working in the below code.. netbeans gets stuck at the running part. it doesn't proceed furthur.. it hangs there forever
body: <p>I have tried to write a code to send email using Java. But this code is not working. When the code is executed it gets stuck at transport.send(message). It's stuck there forever. Also I am not sure if the rest of the code is correct or not. </p>
  
  <pre><code>  //first from, to, subject, &amp; text values are set
      public class SendMail {
      private String from;
      private String to;
      private String subject;
      private String text;
  
  
      public SendMail(String from, String to, String subject, String text){
          this.from = from;
          this.to = to;
          this.subject = subject;
          this.text = text;
      }
  
      //send method is called in the end 
      public void send(){
  
          Properties props = new Properties();
          props.put("mail.smtp.host", "smtp.gmail.com");
          props.put("mail.smtp.port", "465");
  
          Session mailSession = Session.getDefaultInstance(props);
          Message simpleMessage = new MimeMessage(mailSession);
  
          InternetAddress fromAddress = null;
          InternetAddress toAddress = null;
          try {
              fromAddress = new InternetAddress(from);
              toAddress = new InternetAddress(to);
          } catch (AddressException e) {
