Re: [keycloak-user] customize email themes with images

Hi, I now implemented a custom emailtemplateprovider and emailsenderprovider, packaged it (according to the doc) and deployed it. The problem: I am getting a nullpointerexception when keycloak tries to send a test mail. The exception throws in this line: ((EmailTemplateProvider)this.session.getProvider(EmailTemplateProvider.class)).sendSmtpTestEmail(settings, user); The stacktrace does not show any of my custom code, I also have debugger on and keycloak jumps to this line but not in my custom code, so I assume that it is some internal issue. But it must be somehow related with my custom provider, because as soon as I remove it from the deploy directory, email sending works. Any ideas? I don't know if it is useful but I get the following "warnings" when starting keycloak: 16:51:03,806 INFO [org.keycloak.services] (ServerService Thread Pool -- 57) KC-SERVICES0001: Loading config from standalone.xml or domain.xml 16:51:04,036 WARN [org.keycloak.services] (ServerService Thread Pool -- 57) KC-SERVICES0047: CustomDefaultMailSender (xxx.yyy.CustomEmailSenderProviderFactory) is implementing the internal SPI emailSender.

After reading a lot about email client support for image embedding in emails (e.g. the solution from Jérôme is blocked by Outlook), I think the best solution is to implement my own email sender provider and link the images to the attachments (using CID) . @Stian Thorgersen: My understanding is that I will have to override the EmailTemplateProvider based on the FreemarkerEmailTemplateProvider (or can I just extend from this one?) to fetch attachments from a path e.g. /attachments/ and pass them to the EmailSenderProvider, am I correct?

"/> It's not perfect as some email clients (like gmail) don't display this kind of image but it can do the trick before finding a better solution. BR, Jérôme.

Look at docs for details on creating custom providers (as well as quickstarts on examples). Then look at EmailSenderProvider and the implementations in our repo.
