I am trying to inject a service into my bean but it is always null. I get the following error: WELD-001000 Error resolving property userBean against base null.

    Another alternative is use @PostConstruct method annotation.

    @SessionScoped
    public class UserBean implements Serializable {
        @Inject UserService service;
        private User user;
        public UserBean() {
    
        }
    
       @PostConstruct
        void init(){
            this.user = service.findUser("kaas"); 
        }
    
      }
