[keycloak-user] run code at login

i am using TomEE 7.0.3.  i am trying to execute code when the user first authenticates in order to log the ip address and username.  i tried implementing @WebListener public class SessionListener implements HttpSessionListener but the session is created before the redirect to the login system so KeycloakPrincipal<KeycloakSecurityContext> is not available at that point.
