I would suggest using a manager component:
@Name("currentUser")
| @Scope(SESSION)
| @Stateful
| public class CurrentUserManagerBean implements CurrentUserManager {
|
| private User currentUser;
|
| @Create
| public void create() {
| // Initialise the user e.g. get username from JAAS, load user from
Persistence Context
| currentUser = ...;
| }
|
| @Unwrap
| public User unwrap() {
| return currentUser;
| }
|
| }
Alternatively you could make the manager stateful and do all the work in
@Unwrap,
@Name("currentUser")
| @Stateless
| public class CurrentUserManagerBean implements CurrentUserManager {
|
| @Unwrap
| public User unwrap() {
| // Initialise the user e.g. get username from JAAS, load user from
Persistence Context
| User currentUser = em.find(User.class, username);
| return currentUser;
| }
|
| }
or implement a @Factory manager pattern.
@Name("currentUserManager")
| @Stateless
| public class CurrentUserManagerBean implements CurrentUserManager {
|
| @Factory("currentUser")
| public User unwrap() {
| // Initialise the user e.g. get username from JAAS, load user from
Persistence Context
| User currentUser = em.find(User.class, username);
| return currentUser;
| }
|
| }
