public class Roles {    public static final String ADMIN = "admin";    public static final String USER = "user";}

2. Then, let's define a list of tasks to be done based on the role:

@Statefulpublic class UserBean {        @RolesAllowed({Roles.ADMIN})    public void adminOperation(){        System.out.println("adminOperation executed");    }        @RolesAllowed({Roles.USER})    public void userOperation(){        System.out.println("userOperation executed");    }    @PermitAll    public void everyoneCanDo(){        System.out.println("everyoneCanDo executed");    }}
