I'm working with wildfly as for a while and I cant get its mail subsystem working. I have seen many tutorials how to set it up whether through web console, CLI or directly in standalone.xml so I'm pretty sure that my config is right:
<subsystem xmlns="urn:jboss:domain:mail:2.0">
<mail-session debug="true" name="Gmail" jndi-name="java:jboss/mail/Gmail" from="MAILFROM">
<smtp-server outbound-socket-binding-ref="mail-smtp" ssl="true" username="MAILFROM" password="PASSWORD"/>
</mail-session>
</subsystem>
<outbound-socket-binding name="mail-smtp">
<remote-destination host="smtp.gmail.com" port="465"/>
</outbound-socket-binding>
And then in my Java file:
@Resource(mappedName = "java:jboss/mail/Gmail")
private javax.mail.Session gmailSession;
public void sendEmail(String to,String subject,String msg){
Message message = new MimeMessage(gmailSession);
message.setFrom(newInternetAddress("MAILFROM"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject(subject);
message.setContent(msg,"text/html");
Transport.send(message);}
And I get:

The weird thing is that it works with same properties when using javax.mail API directly like this:
public void sendEmail(String to,String subject,String msg){
Properties properties = System.getProperties();
String user = "MAILFROM";
String passwd = "PASSWORD";
properties.setProperty("mail.smtp.auth", "true");
properties.setProperty("mail.smtp.starttls.enable", "true");
properties.setProperty("mail.smtp.host", "smtp.gmail.com");
properties.setProperty("mail.smtp.port", "587");
javax.mail.Session gmailSession = javax.mail.Session.getInstance(properties,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, passwd);
}
});
Message message = new MimeMessage(gmailSession);
message.setFrom(new InternetAddress("MAILFROM"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject(subject);
message.setContent(msg,"text/html");
Transport.send(message);
I'm trying to solve this issue for two reasons:
The second thing i do not understand clearly is why am I getting this exception:

when trying to send email by the second method I mentioned. This error only occurs in case that I am running starting my wildfly server from console with standalone.bat command.. If I am runing it through eclipse "run on server" it works. Confused for a second time. I tried to solve this second problem by adding my selfsigned certificate to jdks cacerts but it didn't help.
What kind of class is your Java code with @Resource in? Most likely the resource is not being injected because your code is not in a managed bean/class of some sort. Check whether gmailSession is non-null to make sure the injection is working.
The cert path error is definitely a problem with certificates in your trust store. Normally the Gmail certificate should validate with the default trust store. Perhaps you have an anti-virus product that's intercepting the request? Did you check the JavaMail FAQ entry?
