Question

なぜこの例外が発生するのですか？solutions.iがmail.jarとactivation.jarをクラスパスに正しくコピーしたことをお勧めします。

javax.mail.MessagingException: Could not connect to SMTP host: your.smtp.host, port: 25;

あなたのSMTP接続が正しいとは限りません。 認証でsmtpの設定を確認してください.. !!

最初の行はすべてそれを言う：

javax.mail.MessagingException: Could not connect to SMTP host: your.smtp.host, port: 25; 
    nested exception is: 

代わりのyour.smtp.hostがあなたがsmtp.gmail.comなど

ようeusing AR SMTPのURLがなければなりませんEDIT：サンプルGmail接続コード

Session session = Session.getDefaultInstance(mailProperties, new javax.mail.Authenticator() { 
      @Override 
      protected PasswordAuthentication getPasswordAuthentication() { 
       return new PasswordAuthentication(mailProperties.getProperty("mail.smtp.from"), "mail.smtp.password"); 
      } 
     }); 
     try { 

      Message message = new MimeMessage(session); 
      message.setFrom(new InternetAddress("xyz@gmail.com")); 
      InternetAddress address[] = new InternetAddress[4]; 
      address = InternetAddress.parse(toMail, false); 
      message.setRecipients(Message.RecipientType.TO, address); 
      address = InternetAddress.parse("reciepents@xyz.com", false); 
      message.addRecipients(Message.RecipientType.CC, address); 
      message.setSubject(subject); 

      BodyPart messageBodyPart = new MimeBodyPart(); 
      messageBodyPart.setText(body); 
      Multipart multipart = new MimeMultipart(); 
      multipart.addBodyPart(messageBodyPart); 
      Transport transport = session.getTransport("smtps"); 
      transport.connect("smtp.gmail.com", 465, "xyz@gmail.com", "pasword here"); 
      transport.sendMessage(message, message.getAllRecipients()); 
      transport.close(); 
     } catch (MessagingException e) { 
      e.printStackTrace(); 
     }
