Is it possible to create email templates outside the war file and use it to send email inside cuba.platform in runtime?
Place the templates files in the tomcat conf directory and use the CUBA Resources component to get the template content. In case of WAR deployment a path to conf directory will be something like this: app_home\app\conf.
“app_home” here is the application directory specified in the deployment settings of Studio, “app” is the application name.
