• 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.
  
  
• Injection des SessionContexts: hier gibt es drei Besonderheiten:
  a) das XML-Pflichtelement <resource-env-ref-name> kann hier einen beliebigen Wert haben, denn da wir uns den SessionContext nicht per JNDI-Lookup selbst holen wollen, ist es egal unter welchem Namen er im JNDI zur Verfügung gestellt wird.
  b) Der SessionContext steht automatisch im Environment Naming Context der Bean unter dem Namen java:comp/EJBContext zur Verfügung (auch wenn er nicht im JNDI-View auftaucht), auf diesen Namen verweist unsere <resource-env-ref> mittels des Elements <mapped-name>.
  c) Die Angabe des Elements <resource-env-ref-type> mit dem Datentyps des Elements (javax.ejb.SessionContext) ist optional, aber kann nicht schaden ;-).
