Hi to all,   I'm trying to develope a custom AuthenticatorFactory with a custom Authenticator.   I would like to inject my custom Authenticator  as Spring Bean into my custom AuthenticatorFactory (because my authenticator should use an existing spring library).   My authenticator is like:   @Component public class MyAuthenticator extends AbstractUsernameFormAuthenticator implements Authenticator { [.]   To achieve it, I created an  ApplicationContextAware bean    @Service public class BeanUtil implements ApplicationContextAware {        private static ApplicationContext applicationContext;            public BeanUtil() {      }        @Override      public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {           this.applicationContext = applicationContext;      }        public static Authenticator getAuthenticatorBean() {            return applicationContext.getBean(MyAuthenticator.class);      }    }   My factory is:   public class MyAuthenticatorFactory implements AuthenticatorFactory, ConfigurableAuthenticatorFactory {        public static final String PROVIDER_ID = "aruba-alias-authenticator";        public static final String G_RECAPTCHA_RESPONSE = "g-recaptcha-response";      public static final String RECAPTCHA_REFERENCE_CATEGORY = "recaptcha";      public static final String SITE_KEY = "site.key";      public static final String NUMBER_KEY = "number.key";      public static final String SITE_SECRET = "secret";        @Override      public String getId() {           return PROVIDER_ID;      }        @Override      public MyAuthenticator create(KeycloakSession session) {           return BeanUtil.AuthenticatorBean();      }   [.]   Keycloak starts up correctly.    When I try to use myAuthenticator, i get:      16:46:48,484 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://0.0.0.0:9990/management sia-keycloak | 16:46:48,484 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://0.0.0.0:9990 sia-keycloak | 16:46:48,485 INFO  [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: Keycloak 4.5.0.Final (WildFly Core 5.0.0.Final) started in 23456ms - Started 943 of 1231 services (653 services are lazy, passive or on-demand) sia-keycloak | 16:47:12,357 WARN  [org.keycloak.services] (default task-3) KC-SERVICES0013: Failed authentication: java.lang.NullPointerException sia-keycloak |  at ...authenticator.alias.BeanUtil.getArubaAliasAuthenticatorBean(BeanUtil.java :22) sia-keycloak |  at ..authenticator.alias.AuthenticatorFactory.create(MyAuthenticatorFactory.jav a:35) sia-keycloak |  at ...authenticator.alias.AuthenticatorFactory.create(MyAuthenticatorFactory.ja va:1)     The reason in that the Spring Context is null.    Any idea about how to fix this issue?     Many thanks,  Tom         _______________________________________________ keycloak-user mailing list keycloak-user(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/keycloak-user
