• Deklaration der im Deployment Deskriptor verwendeten Rollen durch ein Element "security-role" (entspricht der Annotation @DeclaredRoles in der Bean).
• Festlegen der Methodenberechtigungen durch Elemente "method-permission" (entspricht der Annotation @RolesAllowed in der Bean). Hier muss man extrem vorsichtig sein da bei einem Tippfehler z.B. im Bean-Namen keine Fehlermeldungen kommen.
