Hi Ataraxus,

I think the way to solve this is 'tapping in' to the Wildfly module system. You need to add a module.xml to your provider jar under src/main/resources/modules/some/module/name/module.xml and include a reference to the java mail api there. That way you can tell Wildfly to include that on the classpath when it's loading your provider classes.

I'm sorry, but I'm not sure how exactly this works in detail with path names and module.xml contents. You can look at the keycloak sources for module.xml examples, read the Wildfly module system documentation or maybe someone else on the mailing list can answer you in more detail. Good luck!

Here is the code and the stacktrace just in case, maybe there is a better way to send email: 

private void send(UserModel user, AuthenticationFlowContext context, String subject, String textBody, String htmlBody) throws EmailException {
        try {
            String address = user.getEmail();
            Map<String, String> config = context.getRealm().getSmtpConfig();

            Properties props = new Properties();
            props.setProperty("mail.smtp.host", config.get("host"));

            boolean auth = "true".equals(config.get("auth"));
            boolean ssl = "true".equals(config.get("ssl"));
            boolean starttls = "true".equals(config.get("starttls"));

            if (config.containsKey("port")) {
                props.setProperty("mail.smtp.port", config.get("port"));
            }

            if (auth) {
                props.put("mail.smtp.auth", "true");
            }

            if (ssl) {
                props.put("mail.smtp.socketFactory.port", config.get("port"));
                props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
            }

            if (starttls) {
                props.put("mail.smtp.starttls.enable", "true");
            }

            String from = config.get("from");

            Session session = Session.getInstance(props);

            Multipart multipart = new MimeMultipart("alternative");

            if (textBody != null) {
                MimeBodyPart textPart = new MimeBodyPart();
                textPart.setText(textBody, "UTF-8");
                multipart.addBodyPart(textPart);
            }

            if (htmlBody != null) {
                MimeBodyPart htmlPart = new MimeBodyPart();
                htmlPart.setContent(htmlBody, "text/html; charset=UTF-8");
                multipart.addBodyPart(htmlPart);
            }

            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress(from));
            msg.setHeader("To", address);
            msg.setSubject(subject);
            msg.setContent(multipart);
            msg.saveChanges();
            msg.setSentDate(new Date());

            Transport transport = session.getTransport("smtp");
            if (auth) {
                transport.connect(config.get("user"), config.get("password"));
            } else {
                transport.connect();
            }
            transport.sendMessage(msg, new InternetAddress[]{new InternetAddress(address)});
        } catch (Exception e) {
            throw new EmailException(e);
        }
    }

Hey,

I'm writing my custum login provider which works great so far, but i 
stumbled upon a dependency issue:
I wan't to use mail in my authenticator, but when the authenticator gets 
actually loaded I get an class not found exception.
Somehow is java.mail.* not available in the classpath of providers which 
are dropped in the configuration/providers path.
How can i use these dependencies? I could include them into my jar, but 
i guess thats not the "right" way.

Thanks
