Forum: strategy on remote server, how to send email?

thanks for your kindly reply.
i have read this topic before.

quotation:
@Library("mail-1.4.jar")
jar location:
mail-1.4.jar is located in /home/moggy/JForex/Strategies/files/ (my OS is Ubuntu)

add the permission in both files:
/etc/java-6-sun/security/java.policy
/etc/java-6-openjdk/security/java.policy

       // Allow connection to mail server using SMTP
       permission java.net.SocketPermission "*:25", "connect,resolve";
       // Allow connection to mail server using SMTPS
       permission java.net.SocketPermission "*:465", "connect,resolve";

       permission java.net.SocketPermission "*:994", "connect,resolve";

       // Allow connection to mail server using IMAP
       permission java.net.SocketPermission "*:143", "connect,resolve";
       // Allow connection to mail server using IMAPS
       permission java.net.SocketPermission "*:993", "connect,resolve";

       // Allow connection to mail server using POP3
       permission java.net.SocketPermission "*:110", "connect,resolve";
       // Allow connection to mail server using POP3S
       permission java.net.SocketPermission "*:995", "connect,resolve";

sendMail Function:

    public boolean sendMail(String from, String to, String subj, String text)
            throws Exception {
        Properties props = new Properties();
        props.put("mail.smtp.host", smtpServer);
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class",
                "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.port", "465");
        props.put("mail.smtp.auth", "true");
        Session session = Session.getDefaultInstance(props, new MailAuth(
                sendermailadd, senderpassword));
        Message msg = new MimeMessage(session);
        msg.setFrom(new InternetAddress(from));
        msg.setRecipients(RecipientType.TO, InternetAddress.parse(to, false));
        msg.setSubject(subj);
        msg.setText(text);
        Transport.send(msg);
        return true;
    }

I've searched through this forum and find out (Sending an email) that one should use RequiresFullAccess annotation to be allowed send email.
BUT RequiresFullAccess annotation is not allowed in remote strategy code (Remote Run)

In my opinion remote strategy environment is not suitable for such tasks as sending email. And it is not reliable as well (Delay in data feed on Remote Run).

Yeah,exactly,maybe it's commercial but not technical reason.

We plan to add mail sending functionality to API in order to facilitate the mail sending routine and enable its usage in the local run. Meanwhile consider broadcasting your message to a local strategy, which thereafter would send the e-mail:

Hi,

When doing Remote run on a strategy, what is the preferred way to:
- log (i.e., log to file or console so that I can look and/or retreive the log at any time in the future)? Also, are there any limitations on the log size?
- alert myself (e.g., sending myself an e-mail) when something goes wrong?

Thanks.

Regards,
Henrik

Be aware that:
Dukascopy does not guarantee you can retrieve the log - Remote Strategy Log is broken
Dukascopy does not guarantee the log will be complete - Remote Strategy Log suppresses output

Yes, there are. But Dukascopy keep silence about this - Remote Strategy Log size limits

Send e-mail & JFUtils.sendEmail
Broadcast message & IEngine.broadcast
Notification by SMS or email

Hi again,

Thanks hebasto.

Does Dukascopy provide a smtp server, or do I have to provide one myself? If so, can I use my gmail stmp server? If so, how?

Regards,
Henrik

The latter.
https://email.about.com/od/accessinggmail/f/Gmail_SMTP_Settings.htm

the new JDK have add an interface JFUtils.sendEmail to send mail in remote mode.
https://www.dukascopy.com/wiki/#Send_e-mail
it seems that jdk use mail-1.4.jar too~

Now the problem is,when i call myutils.sendMail(smtpServer, from, to, subj, text); it shows exception:
06:19:11 Exception：com.dukascopy.api.JFException: com.sun.mail.smtp.SMTPSendFailedException: 553 You are not authorized to send mail, ...

how to pass the password to JFUtils to authenticate the from mail account?

Hi,

How to use JFUtils.sendEmail(...) on Remote run? Should I specify the smtpServer string parameter as:

"<my_email>@gmail.com:<my_password>@smtp.gmail.com:465"

?

Thanks in advance.

Regards,
Henrik

PS. It would be really nice if Dukascopy could provide a smtp server... =)

The functionality is not working on Remote at the moment, it will be fixed as soon as possible.

Ok, I see.

Please provide a complete example of how to use the JFUtils.sendEmail(...) on Remote run once it works again.

Thanks.

Regards,
Henrik

Fixed with JForex-API 2.9.12.

Great. But how to configure the smtp server when running remotely?

Thanks.

/Henrik

2.9.12 seems to be unavailable from the website now.

It has not been released yet.
We are working on this, but it will not be available with 2.9.12.

Hi again,

Any progress regarding this matter? Please provide complete code example.

Thanks.

Kind Regards,
Henrik

See JavaDoc: https://www.dukascopy.com/client/javadoc/com/dukascopy/api/JFUtils.html#sendMail(java.lang.String,%20java.lang.String,%20java.lang.String)

This should work both local and remote. You don't need to provide smtp server or configure it.
