从glassfish服务器发送邮件时收到错误

Question

我有玻璃鱼服务器我试图通过该服务器发送邮件。但是收到错误。

代码如下

 import java.util.Properties; 
import javax.mail.*; 
import javax.mail.internet.*; 
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import javax.mail.Message;
 import javax.mail.MessagingException;
public class EmailService{ 

  public static void main(String[] args) { 

   String to="to@gmail.com";//change accordingly 
   String from="from@";//change accordingly 
   String password="password";//change accordingly 
   System.out.println("started");
   Properties props = new Properties(); 
   props.put("mail.smtps.host", "localhost"); 
   props.put("mail.smtps.socketFactory.port", "8080"); 
   props.put("mail.smtps.socketFactory.class", 
   "javax.net.ssl.SSLSocketFactory"); 
   props.put("mail.smtps.auth", "true"); 
   props.put("mail.transport.protocol", "smtps"); 
   props.put("mail.smtps.connectiontimeout", "90000");
   props.put("mail.smtps.timeout", "90000");

   Session session = Session.getDefaultInstance(props, 
   new javax.mail.Authenticator() { 
       protected PasswordAuthentication getPasswordAuthentication() { 
     return new PasswordAuthentication("username","password");
     } 
     }); 
    try { 
  System.out.println("started");
  MimeMessage message = new MimeMessage(session); 
  message.setFrom(new InternetAddress(from)); 
  message.addRecipient(Message.RecipientType.TO,new InternetAddress("to")); 
  message.setSubject("Nothing Special.."); 
  message.setText("Send Mail By Java Programmm...."); 
  System.out.println("started");
//send message 
 System.out.println(message);
 Transport.send(message); 
  System.out.println("started");
  System.out.println("message sent successfully"); 

  } catch (MessagingException e) {throw new RuntimeException(e);} 

   } 
   }

但是我收到了一个错误。我更改了端口详细信息。创建的Javamail会话也是glassfishserver。

 javax.mail.internet.MimeMessage@6daa8eb7
