Java EE (Java Enterprise Edition) General Discussion

I'm using latest mail.jar, latest activation.jar, jdk6.

My JavaMail util uses authorization credentials and works fine with my test mail server, but it fails with "javax.mail.NoSuchProviderException: smtp" when I try using my production mail server. The only difference is the connection url and credentials. The production mail server works fine when I use an external pop3 mail client to send/receive (i.e Outlook). The util that sends the mail is contained in a web app running under Tomcat.

I did see earlier topics on this subject but none ever gave a conclusive solution.

I sincerely appreciate any help! - the code follows.

Thanks,

           Properties properties = System.getProperties();
           properties.put("mail.smtp.host", hostStr);

           properties.put("mail.smtp.auth", true);
           Authenticator auth = new PopupAuthenticator(userStr, passStr);
           Session session = Session.getInstance(properties, auth);
           session.setDebug(true);
           Transport tr = session.getTransport("smtp");
           tr.connect(hostStr, userStr, passStr);

           MimeMessage message = new MimeMessage(session);
           Address fromAddress = new InternetAddress(sndrAddr);
           message.setRecipients(Message.RecipientType.TO, toAddresses);
           message.setFrom(fromAddress);
           message.setSubject(msgSubj);
           message.setText(msgBody);

           Transport.send(message);

           ...

    static class PopupAuthenticator extends Authenticator {
        String username;
        String password;
        public PopupAuthenticator(String username,String password){
            this.username=username;
            this.password=password;
        }
        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username,password);
        }
    }
