Make javax.mail and impl as maven scope provided, as TomEE comes with geronimo mail implementation.
Also use resource injection of mail session:
https://dwuysan.wordpress.com/2016/02/17/sending-email-on-apache-tomee/
(If mail account is Gmail, turn ON ‘Allow less secure apps’)
In Tomee.xml:
<?xml version="1.0" encoding="UTF-8"?>
<tomee>
<!-- see http://tomee.apache.org/containers-and-resources.html -->
<!-- activate next line to be able to deploy applications in apps -->
<!-- <Deployments dir="apps" /> -->
<Resource id="tomee/mail/GMailSMTP" type="javax.mail.Session">
mail.smtp.host=smtp.gmail.com
mail.smtp.starttls.enable=true
mail.smtp.port=587
mail.transport.protocol=smtp
mail.smtp.auth=true
mail.smtp.user=<!-- your email address -->
password=<!-- your password, and not 'mail.smtp.password' -->
</Resource>
</tomee>
Injection of resource:
@Stateless
@LocalBean
@Path(value = "workline")
public class MailService {
@Resource(mappedName = "java:comp/env/tomee/mail/GMailSMTP")
private Session smtpSession;
public boolean sendMail() throws NamingException {
final Message message = new MimeMessage(this.smtpSession);
try {
message.setRecipients(Message.RecipientType.TO, new Address[]{
new InternetAddress("someone@gmail.com")
});
message.setSubject("Email from TomEE");
message.setSentDate(new Date());
message.setText("Email from TomEE");
Transport.send(message);
} catch (Exception e) {
Logger.getLogger(this.getClass().getName()).log(Level.SEVERE, null, e);
return false;
}
return true;
}
}
