ich selbst [https://community.jboss.org/people/gris12] created the discussion "security interceptor no access to ejb" To view the discussion, visit: https://community.jboss.org/message/828132#828132 -------------------------------------------------------------- Hi i'm currently new to Jboss development. I have implemented some REST services and now I want to secure them. I have implemented a SecurityInterceptor, but my problem is, I can't access my EJB's in this class. Here ist the code of the interceptor:     @EJB     KryptoManager kryptoManager;     @Override     public boolean accept(Class c, Method method) {         if (c == null || method == null) return false;         //class implementing rest service         return method.getName().equals("restService");     }     @Override     public ServerResponse preProcess(HttpRequest request, ResourceMethod method)             throws Failure, WebApplicationException {         ServerResponse response = null;         String key = kryptoManager.getKryptoInformation();         ...         if (error) {             response = new ServerResponse(LOGINURL, 403, new Headers<Object>());         }         return response;     } The kryptoManager always is null. I also used this method to access bean Information in a servlet and a REST service, were it is working fine. The bean access the database info and delivers them to the controlers, but in securityinterceptor this is not working, why? Here is the rest my classes: The KryptoManager looks like: @Stateless public class KryptoManager {     @EJB     private KryptoDAO kryptoDAO;     public KryptoBean getKryptoInformation() {         return kryptoDAO.getKryptoInformation();     } } @Stateless public class KryptoDAO {      @PersistenceContext(unitName = "adb", type = PersistenceContextType.TRANSACTION)      private EntityManager entityManager;      public KryptoBean getKryptoInformation() {          Query query = entityManager.createQuery("SELECT k FROM KryptoBean k");          return (KryptoBean) query.getResultList().get(0);      } } And the Bean Class looks like: @XmlRootElement @Table(name = "krypto") @Entity(name = "KryptoBean") public class KryptoBean {     @Id     @Column(name = "idkrypto")     private int idkrypto;     @Column (name = "hmackey")     private String hmackey;     public int getIdkrypto() {         return idkrypto;     }     public void setIdkrypto(int idkrypto) {         this.idkrypto = idkrypto;     }     public String getHmackey() {         return hmackey;     }     public void setHmackey(String hmackey) {         this.hmackey = hmackey;     } } And the JaxRsActivator looks like: @ApplicationPath( "/rest" ) public class JaxRsActivator extends Application {     @Override     public Set<Class<?>> getClasses() {         // TODO Auto-generated method stub         return super.getClasses();     }     @Override     public Set<Object> getSingletons() {         // TODO Auto-generated method stub         return super.getSingletons();     } } -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/828132#828132] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
