Payara – Mail Resources

Running an application in Payara you can use a Mail Resource to send mails via SMTP.

In your Java EE code you can inject a Mail Resource by its name:

@Resource(lookup = "mail/my.mail.session")
....
Transport trans = mailSession.getTransport("smtp");
trans.connect();
.....

The Mail resource can be declared in the Payra Web Admin Console in the section “Resources ->JavaMail Sessions”.

Or you can define a mail resource directly in the domain.xml file:

....
 <resources>
  ...
  <mail-resource auth="false" host="smarthost" from="info@foo.com" user="admin" jndi-name="mail/my.mail.session"></mail-resource>
  </resources>
  <servers>
    <server config-ref="server-config" name="server">
      ....
      <resource-ref ref="mail/my.mail.session"></resource-ref>
    </server>
  </servers>
....

If you define the mail resource directyl in your domain.xml file take care about the ‘resource-ref’ declaration in the seciton ‘<servers>’. If you miss this, than your application will not find the mail resource to be injected!
